Starting device for a single phase induction motor |
摘要 |
A starting device for a single phase induction motor can reduce the power consumption and restart in a short time. The starting device for the single phase induction motor having a main winding and a starting winding comprises a starting positive temperature coefficient thermistor connected in series with the starting winding, a bidirectional current control device connected in series with the starting winding and the starting positive temperature coefficient thermistor, and an auxiliary positive characteristic thermistor having a heat capacity smaller than that of the starting positive temperature coefficient thermistor connected in parallel with the starting positive temperature coefficient thermistor, a terminal of the auxiliary positive temperature coefficient thermistor being connected to a gate of the bidirectional current control device.
