Aerotech BM Series Brushless Rotary Motors

  • Neodymium Iron Boron Rare-Earth Magnets
  • Skewed Stator with Multi-Pole Design
  • Standard NEMA Frame Sizes


The Aerotech BM Series Brushless Rotary Motors feature neodymium iron boron magnets for maximum torque and acceleration in a small package. A skewed stator design and an eight-pole rotor provide low torque ripple and smooth velocity. Unlike DC brush-type servomotors, the BM series are brushless and maintenance free. This makes them ideal for critical applications where downtime cannot be tolerated. In addition, the BM series motors have very high power density resulting in high torque in a compact package. Optional IP65 sealing make these motors ideal for harsh environments such as machine tool.

The BM motor series covers a wide range of torque and package sizes. Continuous output torque ranges from 0.16 N-m (22.5 oz-in) to 31.6 N-m (280 lb-in), with peak torques to 94.9 N-m (840 lb-in). Standard frame sizes include NEMA 17, 23, 34, 42 and 56. This makes it easy to mount any motor to Aerotech's gearbox line with no adapter plates. These motors are well-suited to general purpose and high-end servo applications.

Product Family: BM, BM22, BM75, BM130, BM200
