TBM™ Series Frameless Motors

Compact and efficient, the TBM™ Series is designed to be directly embedded in your machine using the machine’s own bearings to support the rotor. These torquer brushless motors are optimised to deliver high torque at relatively low speeds in low-voltage applications such as robotic joints, mobile robots and other battery-operated machines.

Features

  • Multiple frame sizes ranging from 60 mm (2.36 inches) up to 129 mm (5.08 inches) OD
  • Standard windings optimised for 24/48 VDC
  • Low-cogging designs
  • 155°C internal winding temperature (continuous operation limit)
  • Stainless steel rotors for corrosion protection
  • Banded Rotors
  • RoHS Compliant
  • CE compliant at rated voltage
  • Custom windings available
  • Latching hall effect sensors available, pre-aligned and factory-installed
  • Modify any standard product’s characteristics—mechanical dimensions, electrical options and connections, thermal and winding optimization for acceleration or deceleration, torque, speed, power, smoothness, and more—to meet your specific needs
