KPR Motor
1 / 5
The direct drive motor is a top-performing servo solution that requires no maintenance. This motor comes in two different structures - inner rotor and outer rotor - to cater to a variety of application needs. With diameters ranging from 60mm to 500mm and continuous torque from 10N.m to 6000N.m, there are over a dozen sizes available to choose from. The motor offers high precision, rigidity, and low axial radial runout, with absolute accuracy up to ± 6arc-sec and repeated positioning up to ± 1arc-sec.
