BSM C-Series Servo Motor

BSM C-Series Servo Motor

The BSM C-series has as standard, a higher inertia compared to other ABB brushless motors, thus providing an excellent match for equipment requiring higher inertial matching for the machine. The goal of this series design was to increase torque while reducing package size. The result was a torque increase of up to 50% in some models, with a package reduction of up to 50mm (2 inches).

The BSM C-series provides continuous stall torques ranging from 1.2 N-m (10 Lb-In) to 30 N-m (265 Lb-In). Peak torques are 3 times continuous. The C-Series provides an economical package best used in applications with higher load inertias.

The rotor is a time proven quality design – the reliability has been proven in numerous worldwide applications. The BSM C-series is used in equipment such as moving webs, machine tool, packaging, factory automation, material handling, printing converting, food packaging, assembly lines and many other demanding applications.


  • More torque in smaller package than previous designs 
  • Acceleration torques from 32 Lb-In (3.6 N-m) to 3186 Lb-In (360 N-m) 
  • High output torque at low speed – continuous 10 Lb-In (1.2 N-m) to 1062 Lb-In (120 N-m) 
  • Inertia range .0016 - .038 Lb-In-s2 – 0.57 Lb-In- s2 (1.8 - 42.6 – 644 Kg-cm2) 
  • Standard windings for 160, 300, 600 bus volts- customs available 
  • Premium 200°C moisture resistant, multi-coated wire for reliability 
  • Extra high insulated stator for high voltage and current spike protection 
  • Superior bearings with Exxon PolyrexEM TM polyrex grease to provide 4 times greater life 
  • Rugged industrial construction to provide quality throughout the design 
  • Stock and customs available - IEC/NEMA designs
