Product Advantages

1.Large starting torque, overload capacity is more than 2.5 times of the rated power, suitable for frequent heavy load starting occasions;

2.compact structure, small size, suitable for coal mine face scraper, transfer machine and other workplaces that require high installation space;

3.It reduces the filters and reactors required for long-distance frequency conversion power supply;

4.Eliminate the harmonic pollution of the power grid caused by long-distance frequency conversion power supply;

5.high efficiency, high power factor, basically maintenance-free, reducing maintenance costs.

 Applicable equipment

1.Scraper conveyor;

2.Transferring(crushing)machine;

3.Belt conveyor;

4.Emulsion pumping station.
