The invention discloses a motor control circuit, an electric drive assembly system and a motor vehicle. The motor control circuit comprises a three-phase alternating current motor; in the motor driving mode, the three-phase inverter is configured to receive direct current from an external power battery and output alternating current used for driving the three-phase alternating current motor, and in the direct current boosting charging mode, the three-phase inverter is configured to receive direct current from the external power battery and output alternating current used for driving the three-phase alternating current motor. A three-phase winding in a wire slot of a motor stator of the three-phase alternating-current motor is used as an inductive energy storage element of a direct-current boost charging circuit, and the inductive energy storage element and the three-phase inverter jointly form the direct-current boost charging circuit, so that an external power supply module charges the external power battery through the direct-current boost charging circuit; wherein the number of the wire slots is at least 54.
