Document Type and Number:
WIPO Patent Application WO/2023/202293
Kind Code:
A1
Abstract:
Disclosed in the present application a control method and apparatus for an electric motor, and an electric device and a storage medium. A neutral wire of an electric motor is connected to at least one standby power device. The method comprises: during the running process of an electric motor, if it is detected that the electric motor has a fault, determining an electric-motor fault phase; and controlling the electric-motor fault phase to be switched from the currently connected primary power device to a standby power device. In the present application, when an electric motor has a fault, a primary power device of an electric-motor fault phase is switched to a standby power device. The standby power device is used for replacing the primary power device corresponding to the electric-motor fault phase, such that the electric motor can continue to run after a fault occurs, and the safety risk caused by the electric-motor fault phase is avoided during the running process. Continuous running neither increases the degree of damage of the electric motor, nor shortens the service life of the electric motor.
