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.
