Model TBM Series -Frameless Motors

SHARE
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..
