Abstract
A current detecting apparatus for detecting a current provided by a driver for a motor includes a resistor, a signal isolation module, and a processor. A first end of the resistor is connected to the driver, and a second end of the resistor is connected to the motor. A current provided by the driver passes through the resistor to drive the motor. The signal isolation module is connected between the first end and the second end of the resistor, to receive a voltage signal produced by the current passing through the resistor and isolate the voltage signal to output an isolated signal. The processor is connected to the signal isolation module, to receive the isolated signal and process the isolated signal to detect the current provided by the driver for the motor.
