BSM B-Series Motors

ABB’s BSM B-Series AC brushless servo motors offer the highest levels of performance and reliability our customers have come to expect from ABB servo motors. They achieve the performance of rare-earth-magnet motors but without the rare-earth magnets. The rotor is designed around magnets made from sustainable ferrites, environmentally friendly materials that are less susceptible to sourcing and pricing pressure. For high-precision applications, ABB’s BSM B-Series AC brushless servo motors offer exceptionally low cogging with minimal torque ripple. For machining applications in particular, these features translate to a better finish and higher quality on machined surfaces.


  • Sustainable ferrite non-rare-earth magnet material
  • Torque range:  14.4 – 177 lb/in (1.63 – 20Nm)
  • Inertia range: 0.0031 to 0.0666 lb/in2 (3.51 – 75.2 kg/cm2)
  • High rotor inertial for matching heavier machine inertia loads
  • Optional forced-air cooling to extend torque capability for increased 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
