What is AC geared motor? AC gear motors are electric motors that drive machinery at a fixed speed. They consist of a stator, rotor, and a reduction gear train, also called a reducer. The stator's coils receive an alternating current and produce a rotating magnetic field or torque. Why geared motor is used? A geared motor is a component whose mechanism adjusts the speed of the motor, leading them to operate at a certain speed. geared motor have the ability to deliver high torque at low speeds, as the gearhead functions as a torque multiplier and can allow small motors to generate higher speeds. Electric Gear motors are used in applications that require high output torque and lower output shaft rotational speed, especially where space and available power are limited. This describes a wide range of common equipment applications across multiple industries

Bacterial flagellar motor
The bacterial flagellar motor (BFM) is a rotary molecular motor embedded in the cell membrane of numerous bacteria. It turns a flagellum which acts as a propeller, enabling bacterial motility and chemotaxis. The BFM is rotated by stator units, inner membrane protein complexes that stochastically associate to and dissociate from individual motors at a rate which depends on the mechanical and electrochemical environment. Stator units consume the ion motive force (IMF), the electrochemical gradient across the inner membrane that results from cellular respiration, converting the electrochemical energy of translocated ions into mechanical energy, imparted to the rotor.

Terms and definitions that you can maybe apply to your fan works
I don't know anything about computer or mechanical engineering (it's very funny to me that I am in the Transformers fandom and I don't even care about cars), but I do care about improving my writing. I have gathered a list of terms that sound very sciencey and applicable to mechs, some from Martha Wells's "Murderbot Diaries," some from fanfiction/fandom (shout-out to the Crime in Crystals series by Aard_Rinn and Baebeyza, they wrote Transformers better than any Transformers comic/TV show did), and a lot from just surfing through Google and going, "well, what the hell is this? Okay, but what the hell is THAT?".
Also, as I was writing this post, I ended up getting sucked into this article:
And this really bloated my already long list of terms. Very easy to read if you want to glance it over yourself.
It's not an exhaustive list and who knows if it will be useful to you - but maybe you can reblog with your own add-ons of terms and definitions you think make a Transformers fan work just that much better.
The list is below the cut:
100% CPU Load - CPU is fully occupied with too many processors/applications/drivers/operations - not necessarily synonymous with an overload.
Actuators* - A device that causes a machine or other device to operate (Ex: a computerized unit instructs the actuator how to move the tires on a vehicle); create linear and rotary movement (Ex: A hydraulic actuator on a valve will move that valve in response to a sensor/signal); Linear actuators "move a piston back and forth inside a cylinder to build pressure and 'actuate', or complete an action".
* Think of actuators as devices that help produce linear motion and motors as devices that help produce rotational movement. Hence, some consider actuators as a type of motor. But a motor is not a type of actuator (jhfoster.com).
Alternator - Converts mechanical energy to electrical energy with an alternating current. The stator and rotor inside the alternator work as magnets and rotate to generate the alternating current. Then the alternating current (AC) is transformed into a direct current (DC) that charges the battery.
Archive (Archive files) - used to collect multiple data files together into a single file for easier portability and storage, or simply to compress files to use less storage space.
Arithmetic Log Unit (ALU) - the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).
Augment - Make something greater; increase.
Auxiliary Battery - Designed to run as a backup to the starting battery and provide power to some essential equipment like engine start/stop and other systems that require power while the engine is off to put less strain on the main battery and alternator.
Bandwidth - A measurement indicating the maximum capacity of a wired or wireless communications link to transmit data over a network connection in a given amount of time.
Behavioral Coding - A term used in Martha Wells' Murderbot Diaries; essential, code for behaviors.
Branch Instructions - Use programming elements like if-statements, for-loops, and return-statements; used to interrupt the program execution and switch to a different part of the code.
Branch Predictors - Track the status of previous branches to learn whether or not an upcoming branch is likely to be taken or not.
Buffer - A region of memory used to store data temporarily while it is being moved from one place to another.
Cathodes vs Anodes - Cathodes are the positive electrode while the anode is the negative electrode; electrons flow from the anode to the cathode and this creates the flow of electric charge in a battery or electrochemical cell.
Catastrophic Failure - Complete, sudden and unexpected breakdown in a machine, indicating improper maintenance.
Central Processing Unit (CPU) - Primary component of a computer that acts as its "control center"; complex set of circuitry that runs the machine's operating systems and apps; the brains of the computer. * Components: Instruction Set Architecture (ISA), Control Unit (CU), Datapath, Instruction Cycle, Registers, Combinational Logic, the Arithmetic Logic Unit (ALU), etc...
Clock - Determines how many instructions a CPU can process per second; increasing its frequency through overclocking will make instructions run faster, but will increase power consumption and heat output.
Combustion Chambers - An enclosed space in which combustion takes place, such as an engine; jet engines also have combustion chambers.
Condition Codes - Extra bits kept by a processor that summarize the results of an operation and that affect the execution of later instructions.
Control Bus - Manages the communication between the computer's CPU and its other components.
Control Unit (CU) - Manages the execution of instructions and coordinates data flow within the CPU and between other computer components.
Cybermetal - Element native to Cybertron and Cybertron alone.
Datapath - The path where data flows as it is processed; receives input, processes it, and sends it out to the right place when done processing; datapaths are told how to operate by the CU; depending on instructions, a datapath can route signals to different components, turn on and off different parts of itself, and monitor the state of the CPU.
Diagnostic and Data Repair Sequence - Term used in Martha Wells' Murderbot Diaries; exactly what it sounds like.
Diode - A semiconductor device with two terminals (a cathode and an anode), typically allowing the flow of current in one direction only.
Discrete Circuit vs Integrated Circuit- Single device with a single function (ex: Transistor, diode) vs Devices with multiple functional elements on one chip (ex: Memories, microprocessor IC and Logic IC).
Drivers - A set of files that help software (digital components, such as Microsoft Office) interface/work with hardware (physical components, such as a keyboard); allows an operating system and a device to communicate.
Electromagnetic (EM) Field - A combination of invisible electric and magnetic fields of force; used in fandom by mechs to broadcast emotions to others.
Flags - A value that acts as a signal for a function or process. The value of the flag is used to determine the next step of a program; flags are often binary flags which contain a boolean value (true or false).
Full Authority Digital Engine Control (FADEC) - Consists of an electronic control unit (ECU) and related accessors that control aircraft engine performances.
Gestation Tank - Used in mech pregnancies, you can pry it from my cold, dead hands.
Heads Up Display (HUD) - A part of the user interface that visually conveys information to the player during gameplay.
Heat Spreader - Often used in computer processors to prevent them from overheating during operation; transfers energy as heat from a hotter source to a colder heat sink or heat exchanger.
HUB - A device that connects multiple computers and devices to a local area network (LAN).
Inductive Charging - How I imagine berths work; wireless power transfer (ex: Wireless charger or charging pad used for phones).
Instruction Cycle - Also known as fetch-decode-execute cycle; basic operation performed by a CPU to execute an instruction; consists of several steps, each of which performs a specific function in the execution of the instruction.
Instruction Set Architecture (ISA) - The figurative blueprint for how the CPU operates and how all the internal systems interact with each other (I think of it like a blueprint for the brain).
Irising - Term used in fanfiction (specifically the Crime in Crystals series) to describe the action of the of the spark chamber opening ("The Talk", chapter 6, my absolute favorite chapter out of the entire series). I just really liked how the word sounded in that context.
Life Codes - "For those of us who were forged, Primus, through Vector Sigma, generated a pulse wave. Each one a data-saturated life code faster than thought, brighter than light, racing across Cybertron, sowing sparks..." (~Tyrest/Solomus, Volume 5 of More Than Meets the Eye)
Memory Hierarchy - Represents the relationship between caches, RAM, and main storage; when a CPU receives a memory instruction for a piece of data that it doesn't yet have locally in its registers, it will go down the memory hierarchy until it finds it.
Levels: L1 cache (usually smallest and fastest), L2 cache, L3 cache, RAM, and then main storage (usually biggest and slowest); available space and latency (delay) increase from one level to the next
Depending on the multi-core (a core is usually synonymous with a CPU) system, each core will have its own private L1 cache, share an L2 with one other core, and share an L3 with more or more cores.
Motors* - Any power unit that generates motion; electric motors work by converting electrical energy into mechanical energy... when this happens within a magnetic field, a force is generated which causes shaft rotation.
Multitasking Operating System - Allows users to run multiple programs and tasks almost simultaneously without losing data; manage system resources (such as computer memory and input/output devices), allocate resources, enable multiple users, and eliminate long wait times for program execution.
Network - A set of computers sharing resources located on or provided by network nodes. Computers use common communication protocols over digital interconnections to communicate with each other.
Network Feed - The continuously updating stream of content that users encounter on networking platforms.
Neural Network - A type of machine learning process that uses interconnected nodes (like neurons) to teach computers to process data in a way similar to the human brain; a form of deep learning that can help computers learn from their mistakes and improve their time.
Nimbus - A luminous cloud or a halo surrounding a supernatural being or a saint; has been used in fanfiction synonymously or in junction with the corona of the spark.
Nodes - A connection point between devices that allows data to be sent and received between them.
Oil Sump/Oil Pan - Don't forget to change your mech's oil.
Out-Of-Order Execution - A paradigm used to minimize downtime while waiting for other instructions to finish; allows a CPU to choose the most timely instructions to execute out of an instruction queue.
Overload - Orgasm; an electrical overload occurs when too much electricity passes through a circuit, exceeding its capacity; an information overload is when a system receives more input than it can process, or a state of being overwhelmed by the amount of data presented for processing.
Pedes - Feet
Pipelining - A technique used in computer architecture that allows a processor to execute multiple instructions simultaneously, improving overall performance.
Processing Capacity - The ability and speed of a processor, and how many operations it can carry out in a given amount of time.
Program Counter - A special register in a computer processor that contains the memory address (location) of the next program instruction to be executed.
Programmable Nanobots/Nanites - Cybertronian microbots programmed to do work at the molecular level; used popularly for surface healing and pigment in mechs.
Protected Storage - Provides applications with an interface to store user data that must be kept secure or free from modification; a storage method; a function in mainframe hardware.
Protoform - Formed of an ultra-dense liquid metal and are extremely hard to damage; the most basic Cybertronian form of raw, free-flowing living metal; first stage of Cybertronian life cycle
To create a Cybertronian, you need the protoform, the life-giving spark, and alt-form information.
Register - A type of computer memory built directly into the processor or CPU that is used to store and manipulate data during the execution of instructions.
Ex: "When you run a .exe on Windows... the code for that program is moved into memory and the CPU is told what address the first instruction starts at. The CPU always maintains an internal register that holds the memory location of the next instruction to be executed [the Program Counter]"...
Resource Allocations - The process of identifying and assigning available resources to a task or project to support objectives.
Risk Assessment - Focus on identifying the threats facing your information systems, networks, and data and assessing the potential consequences should these adverse events occur.
Routine - A component of a software application that performs a specific task (ex: Saving a file).

*puts a water gun to your head and smiles sweetly* Crow/Amanda
It's my unwavering belief that proper Crow/Amanda MUST involve ship repair and maintenance. Do YOU want ME to write/draw something outside my usual body of work? Asks are open!
“It’s all ours,” Amanda Holliday beams, gloved hands on her hips, as she regards the abandoned jumpship. A true specimen of retro engineering locked in time by the desiccated atmosphere of 10 Pallas, they've been called out by its owner, who asks for nothing in payment except its removal.
“If we can get it to move,” Crow reminds. “Do you really think we can?”
“No ship’s bested us yet.” A determined smile spreads across her face as she opens the hood. "I don't intend for her to be the first!"
Crow approaches, already assessing the motor. Everything he knows about ship repair he learned from Amanda — an impromptu boot camp she insisted on after he almost blew up the Accipiter bringing it to jump-speed without sufficient coolant. So too had he gotten all his gear from her: the toolbelt and safety goggles and mechanic's jumpsuit all rummaged from her workshop. The heavy canvas garment is a smidge short on him and bears Holliday in red embroidery across the breast pocket. Somehow, the signs it's hers makes him cherish it even more.
"Looks pretty good, considering how long it's been here," he says, leaning into the engine bay. Amanda is already chest-deep into the compartment, fiddling around with … he can't see past the parts in front of him. "Maybe a little corrosion on the rotors."
"Stators," Amanda corrects.
"Stators, right."
"Gimme the wrench, would'ya? Blue handle," she specifies, and Crow rummages through the toolbox to find it. Hands it to her, their gloved fingertips brushing as he passes it off.
While she works on that, he tasks himself with cleaning rust, checking wiring against schematics sent to Glint, and sweeping out a long-abandoned bird's nest in the turbine. Hours of pleasantly monotonous work pass. Amanda eventually emerges, smudged in more grease than usual, and climbs into the cockpit to run system tests. Finds the power shot.
Crow rotates sternward, locating the fuel cell. Disengages the lock, and pulls the handle — nothing. He gives the block a second yank, two-handed this time, and still cannot move it.
"We might have a little problem," Crow hedges, and Amanda wanders out back. "The cell's stuck. Like, stuck-stuck."
"Ah, for the love of—" Amanda mumbles, bracing herself against the ship with one leg, and giving it a pull. She doesn't unseat it, but manages to budge it slightly.
"Maybe if we both pull. . ." Crow approaches behind Amanda, "May I?"
Amanda nods. There's no way not to press against as he wraps his chest around shoulders, gripping the pull on either side of her hands. She counts down, three-two-one, and they heave together. The flex of her muscular triceps against his sinuous arms flusters him enough that he has to remind himself to hold on —
There's a heavy mechanical clack as it slides from the receptacle, both giving a long exhale of relief.
When they finally replace it and finish diagnostics, the ship starts easily. Amanda excitedly springs from the cabin, practically jumping into Crow's arms with jubilation. "We did it!" She exclaims, as he swings her around in a hug.
"I'm so happy I could –" she looks into his eyes, and flicks her gaze away with a rosy blush. "Well, I could kiss y–"
He presses his lips to her forehead in a quick, sweet kiss. "I could too."

Torque in induction motor and relationship with power factor.
the torque in induction motor is proportional to the product of flux per stator pole and the rotor current one more term we will take in account is power factor of the rotor.
T → φ * I₂ * cos∅₂
Where φ - flux per status pole
I₂ - rotor current
cos∅₂ - rotor power factor
The induced rotor EMF E2 is proportional to flux per status φ.
Therefore T = K1 * E₂ * I₂ * cos∅₂
Where K1 is another constant.
∅₂ phase angle rotor current and rotorEMF.
From the above equation it is clear that when φ2 increases cos∅₂ decreases and vice versa.
due to the revolving stator flux EMF is induced in rotor conductor, and this EMI is also sinusoidal.
When rotor is non inductive.
φ₂=0
in this case rotor current is in phase with rotor EMF. So the instantaneous value of torque is product of instantaneous value of flux and current. It is seen that torque is always positive.
When rotor is inductive load.
in inductive load I₂ lags behind E₂ bY an angle φ2.
φ2 = tan-¹(X₂/R₂ )
R2 = rotor resistance per phase
X2 = rota reactance per phase at standstill.
Its clear from diagram that portion of torque is reverse direction and hence the total torque is difference of forward torque and reverse torque. When φ2 = 90 degree then reverse torque equals to forward torque and total torque is equals to zero so the motor will not run.

how is electric motor work
How they work
Motors have many different working parts in order for them to continually rotate, providing power as needed. Motors can run off of direct current (DC) or alternating current (AC), and both have their benefits and drawbacks. For the purpose of this article a DC motor will be analyzed, to read about AC motors,
The main parts of a DC motor include:
Stator: The stationary part of the motor, specifically the magnet. Electromagnets are often used in order to provide more power.
Rotor: The coil that is mounted on an axle and spins at high speeds, providing rotational mechanical energy to the system.
Commutator: This component is key in DC motors, and can be seen in Figure 3 and 4. Without it, the rotor would not be able to spin continuously due to opposing forces created by the changing current. The commutator allows the rotor to spin by reversing the current each time the coil does a half turn.
Power source: Supplies an electromotive force which causes current to flow in the system.
Brushes: These are connected to the terminals of the power source, allowing electric power to flow into the commutator.

TL;DR - This person has accidentally turned soup into an electric car.
I'm fairly sure this is the result of an induction hob causing a rotating magnetic field which is drawing the pan along like the dynamic core of an electric motor.
When you create a moving electrical current, it generates magnetic fields around itself. The fields are always perpendicular to the current, and so every electric field also generates a magnetic field at 90° like a pair of overlapping waves.
The induction loop in this hob is operating as a stator, and the super-high voltage current running through it clockwise is causing a powerful magnetic field. This is normal and is how induction hobs work.
Normally, this current isn't strong enough to move the pot: instead, the pot metal resists the pull of the magnetic field. Metals do not like being moved by magnetic fields, and when you try to move them they will instead try to NOT move and will turn that energy into a magnetic field that is opposing in direction. This generates a lot of heat. In an induction hob, we exploit that to generate a lot of heat INSIDE the metal of the pan, which is why an iron pot placed on an induction stove heats up without the glass hob itself generating any heat.
In this case, though, I'm guessing that there's a layer of lubricating oil or some other liquid under the pot, possibly from a spill out of the pot as it cooked, that is cushioning the pot's base and preventing the weight of it from generating any friction. This allows the magnetic fields, which are really rather powerful, to drag the pot around and around in the same direction as the current.
The induction hob is acting as a stator, and the pot is acting as a dynamic core. The two have become electromagnetically coupled together and are now operating as a brushless electric motor - which is the kind used in electric cars.
So yeah this person fucked up soup so bad that it turned their soup into an electric motor.

What Is The Main Rotor Function?
Introduction
The rotor is a crucial component in various mechanical and electrical systems, playing a pivotal role in their functionality. Understanding the main rotor function is essential for anyone involved in engineering, aviation, or motor technology. This article delves into the intricacies of the rotor, its significance, and its applications, particularly focusing on its role in high-speed motors.
Understanding the Rotor
The rotor is the rotating part of an electrical or mechanical system. It works in conjunction with the stator, the stationary part, to create motion or generate electricity. In essence, the rotor converts electrical energy into mechanical energy or vice versa, depending on the application.
Types of Rotors
There are several types of rotors, each designed for specific applications. The most common types include:
Squirrel Cage Rotor: Used in induction motors, known for its simplicity and durability.
Wound Rotor: Found in slip ring motors, offering better control over speed and torque.
Permanent Magnet Rotor: Utilized in synchronous motors, providing high efficiency and precision.
Rotor Construction
The construction of a rotor varies based on its type and application. Generally, it consists of a core made of laminated steel sheets, which reduces energy losses due to eddy currents. The core is surrounded by conductive bars or windings, which interact with the magnetic field to produce motion.
Main Rotor Function
The primary function of the rotor is to convert energy. In electric motors, the rotor transforms electrical energy into mechanical energy, enabling the motor to perform work. Conversely, in generators, the rotor converts mechanical energy into electrical energy, supplying power to various devices.
Energy Conversion
In electric motors, the rotor receives electrical energy from the stator's magnetic field. This interaction generates a force that causes the rotor to spin, producing mechanical motion. In generators, the rotor is driven by an external mechanical force, such as a turbine, to generate electricity.
Speed and Torque Control
The rotor plays a vital role in controlling the speed and torque of a motor. By adjusting the rotor's design and the type of motor, engineers can achieve the desired performance characteristics. For instance, a wound rotor allows for precise control over speed and torque, making it ideal for applications requiring variable speeds.
Rotor for High-Speed Motors
High-speed motors demand rotors that can withstand extreme conditions and deliver consistent performance. The rotor for high-speed motor applications is typically designed with advanced materials and engineering techniques to ensure reliability and efficiency.
Material Selection
High-speed motor rotors are often made from high-strength materials, such as carbon fiber or advanced composites, to endure the stresses of rapid rotation. These materials offer excellent strength-to-weight ratios, reducing the overall mass of the rotor and enhancing its performance.
Cooling Mechanisms
To maintain optimal performance, high-speed motor rotors are equipped with efficient cooling mechanisms. These may include air or liquid cooling systems that dissipate heat generated during operation, preventing overheating and ensuring longevity.
Balancing and Precision
Precision balancing is crucial for high-speed motor rotors to minimize vibrations and ensure smooth operation. Advanced manufacturing techniques, such as computer-aided design (CAD) and computer numerical control (CNC) machining, are employed to achieve the required precision and balance.
Applications of Rotors
Rotors are integral to a wide range of applications, from household appliances to industrial machinery and aviation. Some notable applications include:
Electric Vehicles: Rotors in electric motors drive the wheels, providing efficient and eco-friendly transportation.
Wind Turbines: In wind turbines, rotors convert wind energy into electrical energy, contributing to renewable energy generation.
Helicopters: The main rotor in helicopters generates lift and thrust, enabling vertical takeoff and landing.
Conclusion
In summary, the rotor is a fundamental component in various systems, responsible for converting energy and enabling motion. Its design and construction are tailored to meet the specific demands of different applications, from high-speed motors to renewable energy solutions. Understanding the main rotor function and its significance can provide valuable insights into the operation and optimization of these systems.
