High efficiency and significant energy saving;
The torque has little impact on the load during low-frequency starting;
The starting current is small and no additional starting equipment is needed;
Small size and light weight
An axial flow fan is installed in the wind hood, which has good cooling effect at various speeds;
Wide application range, it can operate at constant torque below 50Hz and at constant power above 50Hz;
Compared with electromagnetic speed-regulating motors, it saves energy and reduces consumption, has a wide speed-regulating range, simple structure, reliable use and easy maintenance.
