Magnetic Voice Coil Motor

Voice Coil Motor (VCM) 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.
