Cooling tower industry
is suitable for electric drag of cooling tower fan type loads. Using single winding pole changing scheme design, the material utilization rate is high, and the efficiency and power factor are obviously improved compared with ordinary double winding motor. The design power of 6 poles and 8 poles is well matched with the fan load, which is more suitable for the drag of the cooling tower fan. During operation, the noise is offset and the electricity consumption is low. It saves energy while having speed regulation performance, which adapts to the needs of modern social life and is a green and environmentally friendly product.
