Introduction
The TDB-150-037-NH-A direct-drive torque motor features a flat, low-profile external-rotor design with a 150 mm outer diameter and 37 mm height. It delivers 1 N·m continuous torque and 3.5 N·m peak torque. An incremental encoder provides closed-loop commutation for precise, repeatable positioning. The direct-drive configuration eliminates the need for gearboxes, reducing maintenance and improving system compactness.
