The invention provides a power assembly, a motor controller and an electric vehicle. The power assembly comprises a driving motor, a compressor, a compressor motor, a first transmission device and a second transmission device. The power assembly is used for selecting the driving mode of the compressor according to the running state of the electric automobile or the preset running power of the compressor. The motor controller comprises a driving motor driving circuit and a compressor motor driving circuit, and the motor controller is used for selectively outputting different types of driving current according to the running state of the electric automobile and the preset running power of the compressor. According to the power assembly, the motor controller and the electric automobile, the operating power range of the compressor is expanded, and the manufacturing cost of the electric automobile is saved.
