New! Moving Magnet Voice Coil Actuators Feature High Speed, High Acceleration and Zero Cogging

Valencia, 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.

For high accuracy, high repeatability closed loop operation moving magnet voice coil linear actuators require a linear encoder, linear servo amplifier, and programmable motion controller which are available as a complete motion control, plug-and-play system from H2W Technologies.

H2W Technologies, Inc. is dedicated to the design and manufacture of linear and rotary motion products that are used in the motion control industry. The complete line of linear electric motors include: Single and dual axis linear steppers, DC brush and brushless linear motors, voice coil actuators, and AC induction motors. Also offered is a complete line of ball screw, lead screw and belt driven positioning stages.

Other motion control products include: Limited angle torque motors for compact, limited angular excursion rotary servo applications, 3-phase brushless rotary servo motors with matching digital servo amplifiers and permanent magnet linear brakes for fail-safe zero power braking for baggage handling and people moving applications as well as amusement park rides.

With over 75 years combined experience in the linear and rotary motion field, the H2W Technologies team of engineers offers the optimal solution to the most demanding motion control, requirements.
