Silencer® Series Slotless Brushless DC Motors

Slotless brushless DC motors provide zero detent torque for near zero vibration. Utilizing SmCo magnets and a stainless steel housing, the BMS09 is ideal for medical applications where the motor has to withstand autoclave conditions. Utilizing NdFeB magnets, the BSS09 provides excellent value with a lower cost and high torque. Both versions are available in two standard lengths with three standard winding codes.

Custom configurations available upon request. In addition, we offer a variety of electrical options to meet a wide range of commercial and industrial operating specifications.

Reliable Operation

The compact slotless motors are well suited for applications demanding high efficiency, high speed, low acoustical noise and zero detent torque. Typical options include Hall effect feedback or sensorless.
