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.
