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..



Increase Uptime
Reduce the complexity of your machine's design. Directly driving your load by removing failure prone transmissions will decrease the likelihood of costly failures and reduce the need for expensive, preventive maintenance. The end result is a reduced total cost of ownership in your machine.
Features
