AC Brushless Servo BSM motors

The BSM B-Series offers all the performance and reliability our customers have come to expect from ABB servo motors. It has the performance of rare earth magnet motors but without the rare-earth magnets. The rotor is designed around ferrite magnets. This environmentally friendly material is less susceptible to sourcing and pricing pressure. For high precision applications, this motor offers exceptionally low cogging with minimal torque ripple. For machining applications in particular, this translates to a better finish on machined surfaces (increased quality). 


  • Sustainable ferrite non-rare earth magnet material
  • Torque range:  14.4 – 177 lbs-in (1.63 – 20Nm)
  • Inertia range: 0.0031 to 0.0666 lb-in-s2  (3.51 – 75.2 kg-cm2)
  • High rotor inertial for matching heavier machine inertia loads
  • Optional forced air cooling to extend torque capability for additional motor performance
  • Windings potted for additional voltage protection that improves reliability and heat transfer
  • Design is interchangeable with C and N series for machine design versatility
  • Rugged industrial construction
  • cURus/CE certified quality design
