ABSTRACT:
A motor driving system includes a power supply unit, a voltage-stabilizing unit, a signal-generating unit, a comparing unit, and a control unit. The power supply unit provides an input supply voltage to each other unit in the system. The voltage-stabilizing unit includes a voltage-stabilizing element and produces a constant voltage. The signal-generating unit generates an input signal, which varies with high and low levels of the input supply voltage. The comparing unit compares the constant voltage with the input signal to generate a comparison signal. The control unit controls a motor's rotating speed according to the comparison signal generated by the comparing unit. When the input supply voltage is low, a lowest rotating speed is set for the control unit to control the rotating of the motor.
