A motor controller, a powertrain, and an electric vehicle. The motor controller is configured to output a drive current or a heating current to an asynchronous motor. A waveform of each phase current of the drive current is a sine wave, and the drive current is used to control the asynchronous motor to output torque. A waveform of each phase current of the heating current is a square wave or a step wave, and the heating current is used to control the torque output by the asynchronous motor to be zero, and heat a winding of the asynchronous motor. Heat generated by the heating current on the winding of the asynchronous motor heats a power battery via a heat conduction apparatus. The motor controller adjusts a waveform of the heating current to increase heating power.
