A motor controller, a heat exchange system, and a current injection method are provided, to improve heating efficiency of a motor. The motor controller includes a control apparatus and an inverter circuit. The control apparatus is configured to control the inverter circuit to input an alternating current to the motor, where the alternating current has a direct current bias, and the alternating current is used to heat the motor. The inverter circuit is configured to output the alternating current to a direct axis or a zero axis of the motor under control of the control apparatus.
