Low Inertia Voice Coil Motor

Oct. 11, 2018
Moticont's voice coil motor offers positioning to less than 1 micron.

A low inertia, hollow core, voice coil or moving coil linear motor, the HVCM-051-025-019-01, features high acceleration, precise positioning to less than one micron (0.00004 in.), high reliability, and low cost. 


The motor has an open aperture of 0.750 in. The hollow core allows for optics, illumination, laser beams, or cables to pass through. With a 0.50 in. stroke length, a continuous force rating of 4.8 lb. and a peak force of 15.15 lb at a 10% duty cycle, this compact voice coil motor measuring just 2.000 in. dia. X 1.00 in. housing length, is ideal for a wide variety of applications.


Two 10-32 UNF-2B x 0.25 in. deep threaded mounting holes on 1.000 in. centers in the housing and coil makes for flexible and easy integration into new and existing applications. Low inertia, high acceleration, high speed, and zero cogging are benefits of this moving coil or voice coil linear motor. When used in closed loop applications with an optional position sensor, resolutions of less than 1 micron are achievable for millions of cycles. If a longer stroke, higher force, a smaller foot print, or customized mounting is required consult Moticont's team of engineers. All Moticont's voice coil motors are available as complete plug-and-play systems, including, position sensor, controller, amplifier, power supply, and if required, with a linear slide.
