BEI Kimco Magnetics (www.beikimco.com), a subsidiary of Custom Sensors & Technologies (CST), Inc., has been unveiled the DIH18-21-BBNA Brushless Generator. The generator, which is used to power a remote brake health monitoring system, was developed in response to a railroad train signaling application requirement.
The challenging generator requirement demands that at the speed of 10,000 rpm, the generator must be able to supply a continuous voltage output of 40VDC Volts DC. It also requires the generator to be remarkably durable and reliable to withstand the consistently high vibration and shock levels common of a railcar environment.
Measuring 2.1” in axial length and 1.8” in diameter, BEI Kimco’s DIH18-21-BBNA Brushless Generator meet these requirements. At speeds of 11,000 rpm, the generator delivers a constant output of 40VDC. To absorb the intense shock and the relentless vibration associated with the application, BEI Kimco has integrated patented bearing suspension technology to the generator which also improves its reliability and longetivity. The generator was also designed with innovative robust “one piece” housing to effectively eliminate vulnerable attachment points. Similar technology has also been successfully utilized to reduce noise in medical applications demanding minimal acoustical noise levels.
After the development of the product, the generator has been placed in a series of demanding reliability and vibration qualification test protocol.
“The successful completion of the tests is a testament to the robustness of the BEI design,” said Walter Smith, Application Engineer at BEI.
