In this embodiment, the external instruction may be input by an operator or automatically generated by the banknote cassette. When an external instruction is received, the running state of the motor is started to be detected. Whether the motor is running or not is detected firstly, and the judgment can be carried out according to whether a feedback module has a feedback signal or not. And if the motor is not in operation, outputting a shutdown state.
and S102, when the motor runs, acquiring the current rotating speed and the current output load of the motor through the feedback module.
In this embodiment, the output load is a load borne by the output end of the motor when the motor drives the external device to move. The output load may be a force, such as a pressure, applied by an external device.

Step S201, if the rotating speed exceeds a preset standard rotating speed multiplied by a first preset multiple, the running state of the motor is determined to be a locked-rotor state.
And S202, if the rotating speed exceeds a preset standard rotating speed multiplied by a second preset multiple, determining that the running state of the motor is a blocking state.
Step S203, if the rotating speed exceeds the preset standard rotating speed multiplied by a third preset multiple, determining that the running state of the motor is a loop fault state.
In this embodiment, the preset standard rotation speed is a theoretical value, and can be determined through multiple motor tests and manually input by an operator.
Taking a specific application scenario as an example, if the rotating speed exceeds 4 times of the preset standard rotating speed, the motor stalling is indicated. If the rotating speed exceeds 6 times of the preset standard rotating speed, the motor is blocked. And if the rotating speed exceeds 8 times of the preset standard rotating speed, indicating the circuit fault of the motor.
