This open-aperture linear motor features a 2.25-in (57.2-mm) stroke. The HVCM-051-038-019-01 dc voice coil servo motor has a continuous force rating of 4.2 lb (18.8 N) and a peak force of 13.4 lb (59.5 N) at a 10% duty cycle. Capable of high acceleration, deceleration, high speed, and zero cogging, the linear actuator has zero backlash when connected directly to a load. The 0.75-in (19.1-mm) open aperture and smooth motion are well-suited for focusing of optics or laser beams, illumination and passage of cables and vacuum lines. The motor has a body diameter of 2 in (50.8 mm).
