BN23 Brushless DC Motors With Integral Drives

Silencer® Series

BN 23 Brushless DC Motors with Integral Drives

Silencer® brushless DC motors with integral drives provide smooth, quiet and efficient operation over a wide speed range. Each frame size is available in several different lengths, with the electronics optimized for the specific motor’s operating parameters. Moog has already performed motor / drive system integration, mechanically, electrically and thermally and offers off-the-shelf models for a wide variety of applications.

Utilizing bonded neo magnets and Surface Mount Technology (SMT), the BN series motors provide excellent value with their low-cost and high torque. The compact BN motors are well suited for applications demanding low audible noise, long life and ease of installation.

If you have any questions about the Silencer BN motors and drives, or would like to speak with an application engineer, please contact us.
