This application provides a motor controller. The motor controller includes a power supply control circuit, a safety state control circuit, and switching bridge aims. The power supply control circuit is configured to control a backup power supply to supply power to the safety state control circuit. The backup power supply includes a flyback conversion circuit. The power supply control circuit is configured to: in response to that a main power supply operates normally and a bus voltage is greater than a first preset voltage, control the flyback conversion circuit to stop operating. This application further provides a powertrain. Therefore, the motor controller and the powertrain provided in this application can improve reliability of the flyback conversion circuit.
