The development of direct drive servo motor
Von motorsmount, 07:25
Direct drive servo motor is a kind of special brushless permanent magnet servo motor. It can be regarded as a circular linear motor or the servo motor with a large number of poles. Thinks to with a considerable number of poles, direct drive motor can provide high torque at lower speed., generalinduction motor with higher speed and smaller torque compared with direct drive servo motor. Direct drive servo motor can supply lower speed and greater speed. In comparison of the traditional induction motor, the main parameters of direct drive servo motor is torque rather than power.
Take plastic extrusion machines, circular looms for example. Extruder gearless direct-drive servo motor drive system can replace the gear box to save equipment costs, reduce noise and improve dynamic response. Circular loom direct drive servo motor drive system is the world's first one who was developed out. It can achieve good energy-saving effect.
