New Integrated Linear Actuator Provides Convenience, Speed, and Performance



San Marcos, CA - BEI Kimco Magnetics Division introduces its new fully enclosed, linear voice coil actuator assembly with internal bearings to compliment its wide range of linear and rotary actuators, brushless DC motors and controllers for motion control. The Model LA16-27-000A is a non-commutated linear servo-motor with a linear force constant vs. displacement characteristic for simple two wire control.

This new actuator represents a significant technological advance over conventional devices for short-medium stroke applications and provides significant improvements in speed and process throughput in a compact, easy to install and use package.

The voice coil technology, combined with low friction guidance within a compact housing, makes it ideal for proportional valve actuation in medical devices where hysteresis and cog-free operation is required.

Other applications for this model include precision pressure and flow control, medical diagnostic, therapeutic and surgical device control, as as well as semiconductor fabrication. There are also applications in manufacturing, inspection and packaging, the machine tool industry and optical systems.

The assembly comprises a 0.157 in. (4mm) diameter by 0.78 in. (20 mm) long output shaft with internal bearings, flexible coil connection circuit and an anti-rotation feature. The 1.57 in. (40mm) diameter linear actuator assembly features a total stroke of 0.24 in. (6mm), a continuous stall force of 3.03 lb.
(13.5 N) and a 10 sccond peak force of 13.5 lb. (60 N). Electrical time constant is 0.115 milliseconds and mechanical time constant is 2.97 milliseconds.

Other sizes and configurations, including integral sensors, are available on special order.
