Locked-rotor protection method, device and equipment of electric driving system and storage medium

The invention discloses a locked-rotor protection method and device for an electric drive system, equipment and a storage medium. According to the scheme, the locked-rotor protection method comprises the steps that the initial temperature of an IGBT module in a motor controller and the starting torque of a motor when the motor enters a starting state are obtained; taking the moment when the motor enters the starting state as a time zero point, and sequentially delimiting a plurality of time nodes; for a plurality of time nodes, on the premise that the temperature rise empirical value of the IGBT module is smaller than the temperature rise margin, if the time nodes when the actual rotating speed of the motor exceeds the rotating speed threshold value of the motor in the running state do not exist in the plurality of time nodes, if the torque of the motor is not zero, the starting state of the motor is maintained, and if the torque of the motor becomes zero, the starting state of the motor is maintained. If so,
