AC induction motor to start at the rated voltage, the initial start-up current is large. Often many times more than the rated current
(typically 5 to 7 times). In order to reduce the starting current and do not make an impact on the grid, usually with reduced voltage
method to start AC induction motor. The product is based on high-voltage starting characteristics of asynchronous motor design,
matching motor power is 220 ~ 1400KW.
