Voice Coil Motors

General Details

Voice Coil Motors

Linear DC MotorsVoice Coil Motors (VCM) or Voice Coil Actuators (VCA) are the simplest type of electric motors. These motors consist of two separate parts; the magnetic housing and the coil. Applying a voltage across the terminals of the motorcauses the motor to move to one direction.

Material: NdFeB, SmCo, AlNiCo

Shape: Custom

Dimension: Custom

Grade: Custom

Advantages of Voice Coil Motors

-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
