阪神のジェットカーと言えばその比類なき高加速力で知られているんだけど、セッティングを見ると何ていうかひっくり返っちゃうんだよね

たとえば5700系、190kwモータを編成で12基吊ってるんだけど、どう考えても4両つなぎの電車にしてはオーバースペックなんですよ。4km/h/sの加速力を出すにしてもこんなパワーは要らない。じゃあ何に使っているかと言えば、空転防止なわけですよ

5700系のギアリングはなんと6.06。5500系よりも2段も浅いギアリングなんです。つまりギアリングが浅くなった分をモータのトルクで補償する。だから起動時の電流は5500系よりも大きくなるからパンタグラフを1個増設して3基にしてるわけ

そんでもってモータをPMSMにしたってことはインバータとの関係は個別制御しかありえない。そうなれば空転管理もより精密になる。だから5700系の走りは5500系よりも数等高級になったわけです。特に雨の日の路面に食いついたような力強い加速はさすが阪神電車と思わせます。とことん走りに対して妥協がないんですよこの電車

ついでに言うとこのセッティングだと定格速度も48～50km/hくらいになるんで、言うなれば定トルク領域終端まで4km/h/sの加速力が維持できてフリーラン領域でも3.0km/h/sくらいの加速力を維持でき、最高認可速度の91km/hまで太いトルクで走れちゃう。

　だから最高速度も引っ張っていけば120km/hくらいまではいけちゃうと思うんですよね。昔ジェットが間合いで準急運用に就いていたけど、5700系なら現行の特急運用、問題なくこなせると思いますよ？　5700系は出足で滑らず高加速でトップの伸びもいい。こと走りに関しては日本一贅沢な電車じゃないですかねこれ

西大阪線を走る5500系。慌てて大物で撮影したのでえらいことに

5500系も110kwモータ全軸駆動というぜいたくさですがギアリングは7.07。そしてまだVVVFが発展途上だったこともあって1C8M制御なんですよ。定格48.1km/hは実に早い脚なんですが雨の日はやっぱり若干やんちゃになる。並列接続とはいえ8モータの面倒を1インバータ、しかも推定式方式で見るわけですから、急激な電圧変動にはどうしても対応できないところはあるんです。せめて1C4Mならねえ…と思うんですが。いやもちろん8モータ直列接続の抵抗制御車5001形なんかと比べりゃあ比較にならない高級な走りをするんですけど

Application of Magnet in Rotor And Stator of Motor

Magnets play a crucial role in the operation of motors, especially in the construction and function of the rotor and stator, which are central components of most electric motors. Here's an overview of how magnets are applied in these components and the advantages they bring to motor operation:

Rotor

The rotor is the rotating part of an electric motor, which turns the shaft to deliver mechanical power. In many types of motors, especially in brushless DC motors and permanent magnet synchronous motors (PMSMs), the rotor includes magnets.

Application:

Permanent Magnet Rotors: In these designs, permanent magnets are affixed to the rotor. When the stator's electromagnetic field interacts with the magnetic field of the rotor's permanent magnets, it causes the rotor to turn. The specific arrangement and type of magnets can vary based on the motor design, aiming to optimize the magnetic interaction for efficient rotation.

Stator

The stator is the stationary part of an electric motor, consisting of windings or coils that, when energized, create a magnetic field that interacts with the rotor to produce motion.

Application:

Electromagnetic Field Generation: In the stator, electricity is passed through the windings to generate a magnetic field. This field interacts with the magnetic field of the rotor (whether from permanent magnets or induced magnetism in the rotor's metal), causing the rotor to rotate.

Control and Efficiency: In motors like induction motors, the stator's magnetic field can be precisely controlled by adjusting the electric current through the stator windings. This allows for control over the motor's speed and torque. In synchronous motors, the stator's field interacts with a field on the rotor that is synchronized with the stator field, leading to efficient and controlled motor operation.

Advantages of Using Magnets in Motors

Efficiency: Motors that use permanent magnets in the rotor can be more efficient than those relying solely on electromagnetic induction. This is because permanent magnets do not require power to maintain their magnetic field, reducing energy loss.

Compact and Lightweight: The use of permanent magnets can lead to smaller and lighter motor designs, as they can produce strong magnetic fields without the need for large windings and iron cores.

No Slip: In permanent magnet synchronous motors, the rotor rotates at the same frequency as the stator's magnetic field (i.e., it's synchronous), which means there's no "slip" as found in induction motors. This results in precise control and efficient operation.

Improved Performance: Motors with magnets in their rotors can offer better performance in terms of speed, torque, and control. This makes them suitable for applications requiring precise motor control and high efficiency, such as in electric vehicles and high-performance industrial machinery.

Durability: Permanent magnet motors often have fewer moving parts and do not require brushes (as used in brushed DC motors), leading to longer life spans and lower maintenance requirements.

In summary, the application of magnets in the rotor and stator of motors is a fundamental aspect that enhances their efficiency, control, and compactness. These benefits are leveraged across various applications, from automotive to industrial and consumer electronics.

Servo Motors in Industrial Automation: Precision, Control, and Efficiency

Servo motors are part of the high-speed industrial automation world, producing precise, controlled, and efficient motion for various applications. Whether it is robotics, conveyor systems, CNC machines, or packaging lines, servo motors make sure that industrial processes are run smoothly with maximum accuracy. In this blog, we will discuss what servo motors are, how they work, their advantages in automation, and why they are indispensable in modern industrial settings.

What is a Servo Motor?

A servo motor is a type of electric motor designed to provide precise control over angular position, speed, and acceleration. Rather than a standard motor, which runs at a fixed speed, a servo motor can vary its speed of rotation and change its position based on input signals. This makes it very useful for applications that need accuracy, such as robotics, automation machines, and CNC machines.

Servo motors consist of a motor (often a DC or AC motor), a feedback device (such as an encoder or resolver), and a controller that processes the feedback signals to adjust motor operations. The feedback mechanism ensures that the motor operates with high accuracy and precision, making it perfect for applications that require consistent and repeatable motion.

Servo motors are integral parts of industrial automation in the modern scene and are essential for obtaining precision in speed, position, and acceleration. A high-quality servo motor ensures exceptional performance; thus, it avails superior accuracy, fast response times, and high efficiency, highly crucial in applications such as robotics, CNC machines, and material handling systems. It enables industries to obtain optimal performance with reduced consumption of energy and minimal downtime by using high-quality servo motors. Advanced materials and sophisticated feedback mechanisms ensure enhanced resilience and reliability, even in challenging environments. Whether it is a matter of precision manufacturing, automated assembly lines, or advanced robotics, high-quality servo motors ensure a high level of operational efficiency, reduced maintenance costs, and consistent, high-precision results.

Types of Servo Motors:

AC Servo Motors: AC servo motors use AC to produce rotary motion, with much higher efficiency and superior speed and torque control. They are thus suited for high power applications.

DC Servo Motors: DC servo motors use direct current and provide accurate speed and position control. They are simpler to control but lack in efficiency at higher powers as opposed to AC motors.

Brushless DC Servo Motors (BLDC): These motors use electronic commutator technology instead of brushes; they are therefore more efficient and longer-lived than DC motors, with less maintenance cost.

Stepper Motors: Stepper motors give exact step-by-step control and thus are known for proper application for positioning without necessarily having a feedback system, usually in low to moderate load applications.

Permanent Magnet Synchronous Motors (PMSM): PMSMs use permanent magnets to create a magnetic field and are noted for their high efficiency, high torque output, and low maintenance, commonly being used in high-performance automation systems.

Applications of Servo Motors in Industrial Automation:

Robotics: In robotics, servo motors are widely applied for accurate positioning, arm movement, and fine control. The motors allow robots to be precise while performing complicated tasks like assembly, material handling, and packaging.

CNC Machines: Computer Numerical Control machines rely on servo motors in performing cutting, milling, or drilling operations. These motors are highly important to accurately move the tool in multiple axes.

Conveyor Systems: Servo motors in automated conveyor systems control the speed and position of conveyor belts. This contributes to the efficiency of handling and packaging materials in industries such as food processing, logistics, and manufacturing.

Packaging Machinery: Servo motors help align and seal packaging materials with high accuracy in packaging machines, improving efficiency and reducing waste.

Injection Molding Machines: The use of servo motors enables precision and efficiency in the control of injection molding, leading to consistently high-quality products with less cycle time.

Servo motors are integral in the industrial automation field, as they have supplied accuracy, speed, and efficiency in a broad range of applications. Efficiency and precision with low energy consumption make servo motors perfect for modern high-performance automation systems. Servo motors enhance the capability of automation systems in all service areas, like robotics, CNC machining, material handling, and reduced downtime, better productivity, and high-quality output. As industries are pushing for more automation and innovation, servo motors will continue to be at the heart of this advancement, changing the future of manufacturing, processing, and assembling.
