When the weight of the goods to be transported is too heavy, in order to effectively transport the cargo, it is necessary to increase the rotational speed of the motor, so it is necessary to increase the current supplied to the motor. However, the above-mentioned active roller controller cannot detect whether the current supplied to the motor exceeds the current. The current that can be loaded by the motor causes the motor to be damaged if the current supplied to the motor is too large, and the active roller controller is burned together, so that it is easy to be dangerous in use.

According to the above, the controller module drives the motor to adjust the rotation speed according to the power signal priority, so as to protect the first protection mechanism of the motor, and then monitor the drive from the drive through the monitoring circuit. The power signal received by the circuit, if the power signal is abnormal, the monitoring circuit immediately transmits the abnormal signal to the controller module, so that the controller module can automatically drive the motor to adjust the rotational speed to the motor module through the driving circuit. The safe speed is used as the second protection mechanism to protect the motor.
