Santa Clarita, CA - An expanded series of non commutated, linear Voice Coil actuators has been introduced by H2W Technologies, Inc. Voice Coil or Moving Coil linear actuators from H2W Technologies, which are capable of producing in excess of 20 g's of acceleration, are available in stroke lengths from .05 in. (1.3 mm) to 3.00 in. (76.2 mm). Direct drive, Voice Coil, linear actuators feature low electrical and mechanical time constants and provide smooth, hysteresis-free motion over their entire speed range, including very low speeds. Voice Coil linear actuators are ideal for positioning applications such as laser beam steering mirrors, optical scanning, tracking, stabilizing, pointing and aiming, hermetically sealed cryo-cooler actuators, pumps, valve actuation, medical instruments and semiconductor manufacturing equipment.

Compact and low cost, non commutated linear actuators provide a more reliable and simpler motion system that can be easily integrated into new and existing designs. Standard models are available from .375 in. (9.5 mm) dia. x .35 in. (9 mm) long, supplying .06 lbs. (.3 N) of continuous force and .18 lbs. (.9 N) peak to 8.0 in. (203.2 mm) dia. x 3.0 in. (76.2 mm) supplying 133 lbs. (591 N) of continuous force and 400 lbs. (1778 N) peak. Custom configurations (force and/or stroke length) can be specificied. Peak acceleration of these low inertia actuators is typically greater than 20 g’s, and move/settle times can be less than 15 milliseconds. When used in a closed loop the typical accuracy is 0.00004 in. (1 micron) and repeatability is 0.00002 in (0.5 micron). Moving magnet versions are also available.

Santa Clarita, CA -- Moving magnet voice coil linear actuators from H2W Technologies offer high speed, high acceleration up to 20 g's, zero cogging, high resolution to 8.3 µm/m (0.0001 in./ft), high repeatability to 5 µm (0.0002 in.), and long life. These high speed linear actuators are ideal for light load applications requiring high acceleration, high accuracy, repeatability, and reliability such as: Mirror tilt and focusing, laser beam steering, position control, Z axis for pick-and-place equipment, robotics, testing, medical diagnostic probes, and hermetically sealed cryo cooler actuators.

Moving magnet voice coil linear actuators feature a small size and a high force-to-weight ratio. Standard sizes feature stroke lengths from 3.8 mm (0.15 in.) to 76.2 mm (3.00 in.), continuous force to 80 N (25.0 lbs) and peak force to 240.3 N (75.0 lbs). Custom designs can also be quickly supplied. Moving magnet voice coil actuators are supplied with bearings and shaft, and power-off magnetic brakes are available for one or both ends of the stroke.
