A motor controller, a heat exchange system and a current injection method are used for improving the heating efficiency of a motor. The motor controller comprises a control device and an inverter circuit. Wherein the control device is used for controlling the inverter circuit to input alternating current to the motor, and the alternating current has direct current bias and is used for heating the motor; and the inverter circuit is used for outputting the alternating current to the direct axis or the zero axis of the motor under the control of the control device.
