Motion Control – Two Axis “Voice Coil” Stages feature: High Speed, and 0.1 Micron Accuracy!

Motion Control - 2 Axis, High Precision Voice Coil Stage

H2W Technologies

Santa Clarita, CA — A New high precision, high speed two axis voice coil positioning stage featuring 0.1 micron resolution encoders for high accuracy and repeatability is available from H2W Technologies. “Voice coil” or “Moving coil” motors are recognized for their low moving mass and high acceleration/deceleration. Therefore voice coil driven positioning stages are ideal for short stroke, closed loop, applications requiring high resolution, and high acceleration/deceleration control. Typical applications can include: Semiconductor testing and assembly, inspection and test, laser micromachining, and applications in research laboratories, and manufacturing, medical, and defense industries.

This compact two axis voice coil driven positioning stage (shown) features a 25 mm x 25 mm (1 in. x 1 in.) stroke, high precision cross roller stages, and two voice coil actuators in parallel driving the bottom stage to double the load and acceleration/deceleration capabilities. Continuous force (top axis) is 10.2 N (2.3 lbs) and 30,7 N (6.9 lbs) peak. The bottom axis has a continuous force of 20.5 N (4.6 lbs) and 61.4 N (13.8 lbs) peak. This two axis positioning stage can be driven with standard DC servo or DC linear amplifiers and a two-axis programmable motion controller.

Pre drilled mounting holes in the base and stage allow for easy installation in new or existing applications. Additionally, voice coil stages are available with strokes of 6.4 mm (0.25 in.) to 76 mm (3.0 in.) and with continuous force to 445 N (100 lbs), peek to 1335 N (300 lbs). Custom Voice Coil stages from H2W Technologies are available as complete plug-and-play positioning systems. Totally custom systems can be shipped in 3 to 4 weeks from receipt of order.
