Advantages of Frameless Direct Drive Rotary Motors! 

This article will discuss a type of motor desirable for various precision machines and other space-constrained applications since it is both small and very efficient. When choosing a frameless torque motor for a space-constrained assembly, size, and weight will be considered. Larger and heavier motors are frequently inefficient and can restrict the design options. After all, you will want to achieve the best motor performance within the confines of the area provided and trouble-free system integration. Choosing the incorrect motor might also be expensive. 

By doing away with the motor's housing, space can be saved. Due to the removal of the housing components, which take up space and frequently cause energy losses, the rotor, and stator can now be mounted directly to the assembly. The end result is a productive system that saves money and physical space.   

What Does Frameless Torque Motor Mean?  

A frameless motor does not have a frame, housing, bearing, or feedback mechanism. Because of this, system vendors may optimize the motor for their application and lower the total cost of ownership. Two elements make up the frameless torque motor. The rotor assembly containing the magnets that provide torque and the armature assembly (stator) with windings are incorporated into a customer-specific application. The ability to design and select the bearings, shafts, housings and sensors needed for the application is a significant advantage.  

Benefits of BMC Motor  

Compact Size: There are two sizes of these frameless motors. These units feature a generous inner bore size despite their compact stature. Due to their compact design, they are simple to incorporate while maintaining lightweight and minimal assembly sizes. Clients can select an 80-millimeter OD with a 20-millimeter stack height or an outside diameter of 50 millimeters with a 14-millimeter stack height.  

High Torque Density: Compared to similar frameless motors, our motors demonstrate a higher torque constant. These frameless motors are incredibly efficient due to their high torque density and efficient conversion of electrical to mechanical power.  

Cost Effectiveness: This motor family is less expensive than other rotary motors of comparable size, and the cost advantage grows as the quantity is increased. Also, consumers save on personnel expenses and time because of their simple integration.  

More Characteristics and Details: With these advantages, our motors have low cogging torque, a maximum operating temperature of 130°C, and compatibility with both low- and high-speed windings.   

Applications of Frameless Torque Motor  

Energy production: Production of wind power  

Industry of food and packaging: Conveyor belt propulsion  

High-precision and high-accuracy technologies in robotics and semiconductor  

HVLS fans are used in industrial or agricultural fan applications.  

Machine tool: Different devices and frameworks that significantly lower prices  

Uses for servo motors  

Conclusion  

Frameless torque motor is here to stay due to their higher production and less construction, size, and component count. Every circumstance is unique and needs to be considered. When variables like space are crucial, employing a frameless motor with much machining will still make sense, even in small quantities or one-offs.

Torque Motor Rotary Table: An Ideal Way to Increase Accuracy and Productivity!

Torque engines have been around since in any event 1970, and like most servomotors of that period, they utilized engines with brushes. As servomotors received brushless innovation, in any case, Torque Motor Rotary Table went with the same pattern and brushless torque engines presently overwhelm the market. They have a few points of interest over different engines.

But, the most obvious feature of torque engines is that they have generally huge distance across to-length proportions, and short pivotal measurements. Also, torque engines can have enormous external and internal measurements, bringing about an engine that is somewhat more than a dainty ring.

The huge breadth enables the engine to grow high torque levels. It gives the engine a huge switch arm to produce significant levels of torque. The enormous diameteralso gives adequate room along the outline for ground-breaking uncommon earth magnets.

Torque engines are also "frameless" engines. This implies they don't have housing, direction, or input devices. In this sense the engine is a unit and intended to be a piece of the machine structure. Torque engines can accompany a reusable gathering help called a "connect," which is set at the production line to guarantee the rotor and stator are adjusted for get together. The extension additionally keeps the attractive field inside the engine, accordingly wiping out the requirement for extraordinary nonferrous get together regions, and keeping harm to the rotor from metal pieces and free screws.

Torque engines are designed as Direct Drive Rotary Table. They kill the requirement for gearboxes, worm-gear drives, and other mechanical-transmission components and legitimately couple the payload to the drive. This makes potential drives with high unique reactions and no hysteresis.

In addition to this, we also offer a catholic range of premium quality CNC Rotary Tables including 4th Axis Rotary Table, 5th Axis Rotary Table and many more. If you want to purchase then contact us today!

Machine tool motor line expands

NUM has expanded its portfolio of motors for machine tool applications by launching a range of high performance brushless torque motors.

Employing optimised magnetics, NUM’s new TMX series direct drive motors have an extremely low cogging torque. They are ideal for applications that demand smooth and accurate rotation, especially at low speeds. Typical uses include direct drive machine tools, rotary tables and radial positioning units.

For direct drive applications, NUM has generally specified use of torque motors produced by IDAM. A member of the Schaeffler Group, this company specialises in direct drive technology and enjoys a tight business partnership with NUM. However, as Massimiliano Menegotto, General Manager of NUM’s main manufacturing plant in Milan, Italy, explained, “A growing number of our customers request customised motors, and prefer to deal with a single supplier for all their CNC machine tool requirements. We have developed the TMX series of torque motors specifically to address these needs. They complement those produced by IDAM and provide us with additional in-house configuration flexibility, enabling us to offer customers an even wider range of solutions.”

NUM is initially launching two TMX series frameless torque motors, with stator diameters of 140mm and 291mm, and intends expanding the range in the future. The motors’ hollow shaft rotors utilise high flux density neodymium-iron-boron (NdFeB) magnets and offer ample internal space for through-motor wiring or mechanical parts. The stator windings are fully protected against over-temperature conditions and are encapsulated within a thermally optimised enclosure that offers a choice of air-cooled and water-cooled configurations.

Like all direct drive motors, the TMX series units are capable of providing continuous torque even when stalled, and are designed for direct attachment to the load. This obviates the need for gearboxes or shaft couplings, to provide highly accurate, backlash-free rotary transmission. The rotor and frameless stator are supplied as component parts and are primarily intended for applications that require total integration of the motor within the servomechanism in order to reduce weight or volume.

NUM’s new TMX series motors can produce a very high S1 torque density and are available with a choice of stator and rotor lengths to best suit the motion requirements of the application. By way of example, a 140mm diameter motor with an active length of 70mm can produce a peak torque of approximately 82Nm at speeds up to 1,500rpm, and a continuous (stall) torque of approximately 50Nm. The motors can be driven by most industry-standard servo drives, including NUM’s MDLU3 and MDLUX drives, which form part of the company’s latest-generation Flexium+ CNC platform.

An Introduction to Frameless Motor Technology! 

The majority of the time, electric motors are viewed as separate parts. For instance, a brushless motor from a standard cordless drill is a self-contained device that can be held in your palm and is approximately the size of a lemon. Typically, it consists of a rotor and a stator that is put together in a housing. These are typically bolted into larger machinery to give the system a rotating motion. A frameless torque motor is devoid of the casing found in conventional electric motors. However, using a frameless electric motor may be helpful in some situations. The rotor and the stator are the two principal pieces that frameless motors have in common with their conventional counterparts. The rotor and stator are mounted directly into the machine assembly in a system using a frameless motor. 

What is a Frameless Torque Motor?  

A frameless motor's rotor and stator components are integrated into a machine assembly to impart torque to a load. In order to complete the servo system, it is often integrated with additional parts such as bearings, feedback devices, housing, shaft, and other elements.  

Pros of Frameless Torque Motor  

Although frameless motors have some specific advantages for some applications, they nonetheless perform the same function as conventional electric motors.  

Efficiency  

Since frameless motors are directly incorporated into a machine's construction, they frequently have high efficiency. In a conventional motor, the bearings or mountings may result in energy loss. Frameless motors remove the sources of these inefficiencies.  

Stability  

Compared to machines powered by regular motors, frameless machines are typically more stable and durable. Furthermore, they frequently have a somewhat superior balance because of the direct integration of motor components.   

Quiet Function  

In general, each extra system component increases the potential for noise. Frameless motors are almost always quieter because they do not have some of the parts that are present in conventional motors.  

Less Maintenance Required  

Similar to the previous point, any new component that is added to a system increases complexity and necessitates maintenance. Aside from using significantly fewer parts than conventional motors, frameless motors also require substantially less maintenance.  

Applications of Frameless Motors  

When very high efficiency and minimal maintenance are necessary, frameless torque motor is frequently utilized in machine tools, centrifuges, and mixers. Robots used in collaboration are an intriguing application. A subclass of robotics called collaborative robots aids human operators in completing jobs without the need for constrictive safety barriers. Frameless motors can be utilized in the joints of a collaborative robot in place of conventional motors and gearboxes due to their strength and small size. They are unnoticeable to the operator and permit the "limbs" to move normally.  

Speak with an expert at BMC Motor about different motor options for your company's requirements, and they will assist you with the best possible option that will fulfill all your needs.
