Handrive Hollow Shaft Three Phase Brushless Synchronous Electric AC Dd Motor

Handrive hollow shaft three phase brushless synchronous electric ac dd motor
Direct drive motor: between the motor and the driven workpiece, direct rigid connection, no need for intermediate links such as screws, gears, reducers, etc., to avoid, to the greatest extent possible, the traditional servo system of backlash inertia, friction, and lack of rigidity of the problem.
Large torque: several times the traditional servo motor.

DDR Motor Advantages:
Increased reliability, reduced control difficulty Increased positioning accuracy Angular second Increased resolution Smoother operation Flexible testing Easy installation Saves energy Saves design space Saves maintenance costs and maintenance time
