Van Nuys, California – Low inertia hollow core voice coil or moving coil linear motors from Moticont feature high acceleration, precise positioning to less than 1µm (0.00004"), and high reliability. The cleanroom friendly, non-commutated motors are available in 23 off-the-shelf standard sizes, Moticont hollow core voice coil linear motors have open apertures of 0.125" (3.2mm) to 2.000" (50.8mm).
The linear motor's hollow core allows for optics, illumination, laser beams, or cables to pass through. For easy integration into new and existing applications these linear voice coil motors are available in five standard outside diameters of 0.625" (15.9mm) up to 3.750" (95.3mm). Stroke lengths are from 0.125" (3.2mm) to 2.500" (63.5mm), the continuous force ratings are from 5.0oz (1.4N) to 16.3 lb (72.4N), and peak forces are from 15.7oz. (4.4N) to 51.5 lb (228.9N) at a 10% duty cycle. Applications include: positioning, medical diagnostics and testing, laser beam steering, dynamic vibration absorption, optical focusing, laser cutting & welding, scanning, assembly, and wafer handling.
Low inertia, high acceleration, high speed, and zero cogging are benefits of moving coil or voice coil linear motors. When used in a closed loop applications with an optional position sensor, resolutions of less than 1µm are achievable, for millions of cycles. 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.
