MOTORS AND MOTOR CONTROL: Silent DC brush motor for aerospace, industrial, and railway applications introduced by Crouzet

Crouzet in San Diego is introducing the soundless DCmind Brush range of direct current brush motors for aerospace applications. The DCmind Brush motors have a noise level of 35 decibels, roughly the sound of a whispered conversation.

Key to its silent operation are high-quality magnets, brushes, and ball bearings, as well as shaped and balanced rotor poles, Crouzet officials say. The DC motor offers more than 80 percent efficiency and has a minimum service life of 5,000 hours when used with normal power loads. Under reduced load conditions, service life can extend to 24,000 hours.
