Cylindrical voice coil motors use high-performance permanent magnets. By electromagnetic and mechanical design and optimization, they have advantages of high force density, low mover mass, smooth motion, and quick response, etc.

Design Feature

A. Direct drive, zero cogging, zero backlash voice coil motors

B. Low coil mass with very fast response and bandwidth

C. No contact between coil and core movement (no wear and tear)

D. Smooth motion at low speeds with limitless resolution (depends on feedback device)
