Control circuit for oil pump controller

The utility model relates to an oil pump controller, in particular to a control circuit for the oil pump controller. The problems of complexity, inconvenience for operation, circuit control inaccuracy, poor power feedback effect and low implementation capability of the control circuit for the oil pump controller are solved. According to the control circuit for the oil pump controller, a power polarity protection circuit is connected with a singlechip speed regulation control circuit and a full-bridge power driving circuit respectively; the singlechip speed regulation control circuit directly controls the full-bridge power driving circuit, and then controls the starting of an oil pump motor; the oil pump motor feeds back information to a rotor position detection circuit, and finally feeds back the information to the singlechip speed regulation control circuit; and the singlechip speed regulation control circuit is also connected with a current limiting protection circuit. The control circuit is simple and conv
