Description

Design Features

  • Available in 8 models with torque ranging from 0.17 N·m to 27.6 N·m
  • Configurable with optional fail-safe holding brake
  • Features optional IP65-level construction for use in harsh environments
  • Available in standard NEMA frame sizes
  • Follows the EU 2015/863 RoHS 3 directive

Wide Torque Range

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.

Application Flexibility

The standard motor has a 1000-line encoder (4000-line count after quadrature), RS-422 line driver output with Hall effect device outputs for commutation, and MS connectors. Options include increased encoder resolution, sealing for IP65 level protection, brakes, and gearboxes. Standard models can be delivered from stock and custom variations can be engineered to your requirements with minimal lead time.
