BS23 High Performance Brushless DC Motors

Silencer® Series

BS23 High Performance Brushless Motors

Utilizing high energy sintered neodymium magnets, the BS23 high performance brushless motor offers almost 2 times the torque capability of the standard BN23. When maximum performance and minimum size are important, the BS23 offers an effective solution.

Finned black motor housing offers excellent heat transfer characteristics. Typical options include electronic drives, encoders, gearheads, as well as Hall effect, resolvers, and sensorless feedback.
