The invention provides a motor controller, a power assembly and an electric automobile. The motor controller, the power assembly and the electric automobile are used for solving the problem of current impact of a power tube when the motor controller is started so as to improve the efficiency of the power assembly and the endurance of the whole automobile. The motor controller comprises a control device and an inverter circuit. The control device is used for sequentially receiving a first torque signal, at least one second torque signal and a third torque signal. The control device responds to the third torque signal, and the control device sequentially outputs a starting signal and a third control signal. The starting signal is used for controlling the inverter circuit to generate starting voltage so as to avoid the problem of current impact when the power tube is conducted. And the inverter circuit receives the third control signal and drives the driving motor to output a torque value indicated by the third torque signal. According to the motor controller, the power assembly and the electric vehicle provided by the embodiment of the invention, the starting speed of the motor controller can be increased, and the starting current impact of the motor controller is eliminated.
