Silencer® BN Series Brushless DC Motors

The Silencer® BN series of brushless motors offers diameters from 1.2 inches to 4.1 inches and lengths from 1.3 inches to 5.5 inches. It offers continuous torques from 2.4 to 519 oz-in and speeds up to 20,000 rpm. Built for rugged applications and environments, the Silencer series motors feature bonded rare earth magnets and aluminum housings. Options include electronic drives, encoders and gearheads, as well as Hall effect, resolver and sensorless feedback. Our very quiet, efficient, brushless design is well suited for applications where low noise and reliable, long life operation are particularly important.
Utilizing bonded neo magnets, our BN series motors provide excellent value with their low cost and high torque. Each frame of the BN motors is available in four different lengths with a variety of electrical options to meet a wide range of commercial and industrial operating specifications.
Reliable, Low-cost Operation
An aluminum housing protects the unit in rugged applications and environments. Typical options include electronic drives, encoders and gearheads, as well as Hall effect, resolver and sensorless feedback.
