WDDM, certified by TUV, ISO 9001, ISO 14001, OHSAS 18001, focuses on designing and manufacturing all kinds of permanent magnet synchronous motors(PMSM) and drivers.

Our principal products include:

1) Permanent Magnet Linear Motors capable of continuous thrust up to 100 kN (22,481 lbf) force;

2) Permanent Magnet Synchronous Motors (PMSM) delivering up to 1,000 kW(1,341 HP) with up to 60 kN.m(44,253 lbf-ft) torque;

The speed of above two kinds of motors can be widely adjusted and always at high efficiency working area by adopting the Variable Frequency Drive (standard equipment).

3) Asynchronous Starting(self-starting) Permanent Magnet Synchronous Motor based on NEMA standard delivering up to 250 kW (335 HP). For this kind of motor, no need Variable Frequency Drive(VFD) to start and has the all advantages of PMSM Motors.
