Linear Voice Coil Motor Provides Precision Motion Control For Optical Focusing and Measurement Applications

Oct 08, 2023

Moticont is introducing the LVCM-019-048-02 linear voice coil motor for laser machining and drilling, wafer handling, optical focusing, dynamic vibration absorption, scanners, and laser beam steering and filtering.

The LVCM-019-048-02 linear voice coil motor has a 1.5-inch stroke length and a force-to-size ratio of 7.4 ounces and a peak force of 23.5 ounces at 10 percent duty cycle.

Voice 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 motor causes the motor to move to one direction. Reversing the polarity of the applied voltage will move the motor to the opposite direction. The generated force is proportional to the current that flows through the motor coil. This force is almost constant in the specified stroke range of the motor.

Voice coil motors are brushless and do not utilize commutation. Their structural stability can support high positioning resolutions presented by external position sensors and motion controllers.

This linear motor has zero cogging and features high accuracy, and high repeatability in work holding and clamping, medical devices, haptic feedback, assembly, and test and measurement.
