Voice Coil Positioning Stages have 0.1 micron resolution.

Press Release Summary:




With up to 2 in. of travel and no force or velocity ripple, voice coil stages suit precise motion control applications such as scanning, lens grinding, and laser and mirror positioning. Direct drive, zero backlash stages have no moving cables and are available with acceleration rates to 10 g, 0-50 lb continuous force, and 150 lb peak force. Closed loop products exhibit smooth motion and require linear servo amplifier.

NEW! 0.1 Micron Resolution Voice Coil Positioning Stages from H2W Technologies



Valencia, CA - High resolution, compact, voice coil stages with up to 50.8 mm (2 in.) of travel, with no force or velocity ripple for very smooth motion are ideal for precise motion control applications such as scanning, lens grinding, and laser and mirror positioning. These direct drive, zero backlash stages with an encoder resolution as low as 0.0001mm (0.1 micron), acceleration up to 98 m/sec2 (10g's), and no moving cables, offer the benefits of higher performance and greater reliability than belt or lead screw mechanical drive systems.

H2W Technologies manufactures a complete range of voice coil stages from 0 to 222 N (0 to 50 Lbs) continuous force and 667 N (150 Lbs peak force). These closed loop voice coil stages require a linear servo amplifier, which is available as a complete motion control, plug-and-play system from H2W Technologies. Options include: Cross roller bearings, force transducer feedback, custom mountings, and complete custom designs.

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 includes: 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.
