The invention provides a motor controller, a power assembly and an electric vehicle. The motor controller comprises a direct current input port, an alternating current output port, an inverter circuit and a breaking device. The DC input port is used for connecting a power battery, and the AC output port is used for connecting a motor. The inverter circuit is used for converting direct current output by the power battery into alternating current to supply power to the motor, the inverter circuit comprises six bridge arms which are connected in parallel, the two ends of the six bridge arms are used for receiving the direct current through the direct current input port, and the middle point of the six bridge arms is used for outputting the alternating current through the alternating current output port. The breaking device is used for connecting or disconnecting the bridge arm midpoint of each bridge arm in the six bridge arms and the motor, and the motor controller is high in safety and reliability.
