Outer Member Rotating BLDC Motor

April 9, 2012

BEI Kimco Magnetics, a brand of Custom Sensors & Technologies (CST), Inc., has introduced the DXH15 Series Outer Member Rotating BLDC Motor to meet the high accuracy requirements for a variety of industrial scanning applications. The new DXH15-10-000A Motor supports extreme inner rotational speed variations by maintaining a shaft run-out of only +/- 0.010. This results in negligible jitter of less than ±0.1%, which was a key requirement in meeting customer performance specifications for a laser barcode-scanning machine used in a production material handling application. The motor’s negligible shaft run-out characteristics prevent the laser beam from rasterizing, which is critical to barcode read accuracy and maximum throughput. The new motor incorporates a proprietary Hall commutation circuit that produces the exacting switch points required by the customer’s control electronics for rotor position sensing. The motor’s precision ball bearings and precision balanced rotor ensure reliable operation at speeds in excess of 11,000 RPMs under continuous duty over the life of the system.
