Bodine Electric Co. (www.bodine-electric.com) is proud to announce the latest brush-wear monitoring system developed for its popular line of 42-frame permanent magnet DC (PMDC) motors and gearmotors. The OEM versions of the type 42A products are equipped with built-in electronic brush-wear sensors, which are fully integrated into the motor housing. These special sensors signal when one of the brushes is nearing the end of its useful life.

The sensor system lets OEMs monitor brush wear electronically to maintain uninterrupted operation of the PMDC motors or gearmotors.

It also removes the guesswork in brush inspection and maintenance. Motors and gearmotors that are equipped with this feature can accommodate built-in EMI filtering and built-in magnetic encoder. The company is already in the process of searching for patent protection for this latest technology. PMDC gearmotors and motors that feature the proprietary design are exclusively available from Bodine.

“This is the sort of value-added and innovative design engineering that sets Bodine apart. One of our customers approached us with the challenge of monitoring brush-wear and motor life in a battery- and solar-powered application. We took care of the motor solution with this new technology, and the customer integrated the sensor feedback into his control system,” said Terry Auchstetter Manager of Custom Solutions and Business Development of Bodine Electric.

The sensor system is best suited for remote monitoring of PMDC motors or gearmotors, especially when nobody is standing next to a machine all day.
