Moticont has added a 0.750 in. (19.1 mm) diameter (smaller than a U.S. quarter) Linear Voice Coil Motor, to their expanding line of voice coil or moving coil motors. The LVCM-019-048-02 Linear Voice Coil Motor is a true servo motor featuring zero cogging, high accuracy, and high repeatability when operated in a closed position loop.  Voice Coil Motors (also referred to as actuators) are clean, quiet, efficient, low inertia, high acceleration, brushless high speed linear servo motors.  This small LVCM-019-048-02 diameter actuator has a 1.500 in (38.1 mm) stroke length and a high-force-to-size ratio of 7.4 oz (2.1 N) and a peak force of 23.5 oz. (6.5 N) at 10 percent duty cycle.

This efficient, low inertia, high acceleration, brushless, high speed linear motor has zero cogging and features high accuracy, and high repeatability. It is ideal for:  Workholding and clamping, medical devices, haptic feedback, assembly, testing, laser machining and drilling, wafer handling, optical focusing, dynamic vibration absorption, scanners and laser beam steering and filtering.

The motor features an 8-32 UNC-2B threaded mounting hole in the center of the housing and on the coil end to easily integrate into new or existing applications.  

As with all of Moticont’s linear actuators, the LVCM-019-048-02 can be ordered as complete plug-and-play system including an encoder and servo controller.
