Low Inertia, High Precision, Hollow Core Voice Coil Motors from Moticont
A low inertia hollow core voice coil or moving coil linear motor from Moticont, the HVCM-051-025-019-01, features high acceleration, precise positioning, high reliability, and low cost. This cleanroom friendly, non-commutated motor is available off-the-shelf. The HVCM-051-025-019-01 hollow core voice coil linear motor has an open aperture of 0.750 in. (19.05 mm). The hollow core allows for optics, illumination, laser beams, or cables to pass through. With a 0.50 in. (12.7 mm) stroke length, a continuous force rating of 4.8 lbs (21.3 N) and a force of 15.15 lbs (67.4 N) at a 10% duty cycle, this compact voice coil motor measuring just 2.000 in. (50.8 mm) dia. X 1.00 in. (25.4 mm) housing length, is ideal for applications such as positioning, medical diagnostics and testing, laser beam steering, dynamic vibration absorption, optical focusing, laser cutting & welding, scanning, assembly, and wafer handling.
Two 10-32 UNF-2B x 0.25 in. (6.4 mm) deep threaded mounting holes on 1.000 in. (25.4 mm) 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, very high resolutions are achievable for millions of cycles. Consult Moticont's team of engineers, if a longer stroke, higher force, a smaller foot print, or customized mounting is required. All of 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.
