Handrive AC Servo Direct Drive Torque Motor for Robot Arm Joint

Direct Drive Motors

A direct drive motor is any motor - rotary or linear - in which the load is directly coupled to the motor without mechanical transmission elements such as gearboxes, rack and pinions, or belt and pulley systems.  In this system, the motor directly drives the load. The reduction in the amount of moving parts increases the efficiency of the system, creates a quiet and highly dynamic motor operation, and increases the lifespan of the system.
