Description of HONPINE TDB-150-037-NH-A Direct Drive Torque Motor
The TDB-150-037-NH-A direct drive torque motor features a flat, low-profile design with a 150 mm outer diameter, delivering 1 N·m continuous torque and 3.5 N·m peak torque. Its external rotor architecture provides superior torque density within a compact footprint. Closed-loop commutation is achieved through an incremental encoder, ensuring precise and reliable motion control. The direct drive structure eliminates the need for gearboxes, making maintenance significantly easier — offering the best cost-performance ratio without compromising positioning accuracy.
