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.
Han Drive DD motor has two types of structure: inner rotor and outer rotor to meet more application requirements.
Diameter from 40mm to 760mm, continuous torque from 0.8N.m to 5000N.m. There are more than a dozen sizes to choose from, absolute accuracy can reach to ± 6arc-sec, repeated positioning up to ± 1arc-sec.Has high precision, high rigidity, low axial radial runout and other advantages.
And handrive motor's integration structure, the motor directly drives the load which eliminates the use of a transmission or a gearbox.The amount of moving parts in the system is reduced tremendously increasing the efficiency and creating a quiet and high dynamic operation. Therefore, direct drive technology achieves a very high lifetime. Our motors are characterized by high dynamic performance and high efficiency.
