Magnetic Rotor & Stator

Today, the newest powerful and efficient electric motors use permanent magnets in their design, instead of powered by an electric current through copper windings. Permanent magnet motors (PM motors) have some key advantages.

Permanent Magnetic Rotor
Magnetic rotor serves as a part of Voice Coil Motor (VCM) which is an electric motor consisting of a permanent magnet and yoke in conjunction with a coil. You can also called it Voice Coil Actuators (VCA). To design a tailor-made VCM, you should take into consideration the magnet material, magnet position, the surrounding structure, etc..

Talk to an Expert

• Linear Control Characteristics: can accelerate quickly and come to a gentle stop at a very precise position.

• Reduced Mechanical Components: Offers a simpler and more reliable alternative to screw-type actuators.

• Barely Hysteresis: make sure consistent performance.

• High Power-to-Mass Ratio.

• Compared with stepper motor or servo motor, it has simply construction and no need commutation.

• Lightweight moving parts offers a quickly high precision and smooth motion control.
