MAVCM Voice Coil Motors (VCM)

Product ID:	MAVCM
Material:	NdFeB, SmCo, AlNiCo
Shape:	Custom
Dimension:	Custom
Grade:	Custom

Voice Coil Motor (VCM), also called Voice Coil Actuators (VCA), is an electric motor consists of a magnet and yoke in conjunction with a coil.
The magnet’s position, the type of magnet, the surrounding structure, etc., can influence the efficiency of the unit.

Advantages of VCM
-No commutation required
-Low to no hysteresis
-Zero cogging
-Fewer mechanical components compared to “screw-type” actuators
-Linear control characteristics
-High power to mass ratio
-High power to volume ratio
-Infinite position (only limited by the encoder device)
-High acceleration

Some examples of applications of VCM
-Shaker/Vibrator
-Lens focusing
-Servo valves
-Positioning Stage
-Speaker
