TBM™ Series Frameless Motors

These torquer brushless motors are optimized to deliver high torque at relatively low speeds in low-voltage applications such as robotic joints, mobile robots and other battery-operated machines. 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..

Thru-bores from 5 mm (0.2 in.) up to published maximum (refer to outline drawing)
Mounting Customer-specified bolt-hole diameter and circumferential pattern
Lead length Base model: 152 mm (6 in.) min.
Customer-specified: 150 mm (5.9 in.) to 1200 mm (47 in.)
Lead colors Base model: red, white, black
Other colors, customer-specified
Thermal sensor PTC or linear thermistor-type devices
Speed/Torque Capabilities Standard Modifications
Winding gauges Wide winding range available (includes lead wire change)
Stack lengths 3-5 stack lengths available depending on frame size
