Actuator with flexure design prevents shaft rotation inaccuracies

BEI Kimco has released a voice coil actuator (VCA) for extreme precision applications in aerospace, clean rooms, laboratory instrumentation, and medical environments. It comes with a moving magnet and a flexure design, which ensures high alignment accuracy and prevents unwanted shaft rotation.

The new actuator incorporates a shaft with flexures at both ends of travel, which supports the moving magnet field assembly. That, in turn, enables the Housed Linear Actuator Model LAH13-11-000A to prevent shaft rotation inaccuracies.

The flexure design also eliminates friction and side-loads at non-vertical angles as well as unwanted accumulation caused by shedding from bearing and bushing. Moreover, it safeguards actuator's inherent ability to return the magnet to mid-stroke when re-energized.

BEI's plug-and-play actuator offers a peak force of 11.9 N and a continuous stall force of 0.7 N in a small, lightweight package that measures 36 x 30 mm and weighs 0.22 lbs.
