Claim 0:
1. A motor control circuit, comprising:
a first switch module,
a three-phase inverter, and
a control module, wherein:
a power supply module, the first switch module, the three-phase inverter, and a three-phase alternating current motor form a current loop,
midpoints of three phase legs of the three-phase inverter are respectively connected to three phase coils of the three-phase alternating current motor,
the three-phase alternating current motor inputs or outputs a current by using a wire N extending from a connection point of the three phase coils,
the control module is separately connected to the three-phase inverter, the first switch module, the three-phase alternating current motor, and the power supply module, and
the control module controls the three-phase inverter, so that the motor control circuit receives a voltage of the power supply module and outputs a direct current.
