IPM Servo Motors

  • The permanent magnet is located inside the rotor, the structure of the rotor is simple, high mechanical strength;
  • The surface of the rotor is silicon steel sheet, with low surface loss;
  • The equivalent air gap is small, but the air gap magnetic density is high, suitable for weak magnetic control;
  • High degree of freedom in the shape and configuration of permanent magnets;
  • Can effectively utilize the reluctance torque to improve the torque density and efficiency of the servo motor.

Permanent magnet synchronous servo motor, a kind of AC permanent magnet servo motor, is widely used in the field of small and medium-capacity high-precision transmission to generate magnetic field by adding permanent magnets to the rotor. Due to the inherent properties of permanent magnet materials, it no longer needs external energy to establish a very strong permanent magnetic field in the space around it. This simplifies the motor structure and saves energy.
Permanent magnet synchronous servo motor characteristics:

  • High power factor and high efficiency;
  • Simple structure, reliable operation;
  • Small volume, light weight, low loss.
