Abstract: The present disclosure provides a troubleshooting system for current sensors including a motor, three current sensors and a controller. The three current sensors respectively sense three phase currents of the three-phase current of the motor to obtain three current sensing values. The controller is configured to control the three-phase current of the motor. When the sum of the three current sensing values is greater than a threshold, the controller controls the three phase currents to be zero, and a first offset sensor and a current offset are obtained. When the sum of the three current sensing values equals the current offset, a second offset sensor is obtained. If the first offset sensor and the second offset sensor are the same current sensor, the controller outputs a warning signal, if the first offset sensor and the second offset sensor are different current sensors, the controller controls the motor to stop operating.
