BS12 High Performance Brushless DC Motors

Silencer® Series

BS12 High Performance Brushless DC Motor

The BS12 is a very high energy size 12 BLDC motor. Utilizing rare earth sintered magnets and hand inserted stator windings, this high performance brushless DC motor has a very high torque / volume ratio. Ideal for applications requiring a high energy, high efficiency BLDC motor where space is limited.

Hall-effect feedback is standard with sensorless or resolver feedback optional. Other options include gearheads and ballscrews. Custom solutions available.
