Voice Coil Actuator Delivers Low Hysteresis/Low Friction for Precise Motion Control

Voice Coil Actuator Delivers Low Hysteresis/Low Friction for Precise Motion Control
BEI Sensors

For some applications, inconsistent motion caused by excessive friction is simply not an option. The LAH15-19-000A Linear Voice Coil Actuator (VCA) promises extremely low hysteresis/low friction with precise and consistent bi-directional position control. Initially designed to meet the exacting requirements of an anesthesia machine, the VCA will serve well for other applications where low friction and high force accuracy are needed.

Key to the VCA's new low-friction design is a patent-pending symmetrical flex circuit that prevents friction caused by movement to ensure consistent, reliable results. A solid brass ball cage with captured steel balls further reduces friction. These design features combine to deliver an operating performance with a hysteresis of just 10 mN compared to similar style actuators that deliver as much as 50 to 200 mN. BEI Kimco's low-friction design can also be incorporated into the company's standard and custom VCAs.

Other performance attributes of the new LAH15-19-000A VCA include a peak force of 4.7 N, a total stroke of 7.4 mm and a compact size of just 38 mm in diameter by 48.3 mm in length.
