ABSTRACT:
A sensorless SRM suitable to drive the SRM based on the position of a rotor detected through the detection of the variation of the current of each phase without providing separate sensors for identifying the position of the rotor includes a motor driving part for driving the motor by exciting phases of the motor in a predetermined sequence, a differentiating part for differentiating the currents exciting the phases of the motor respectively, an amplifying part for amplifying output voltages from the differentiating part to proper levels, and a comparing part for comparing output voltages of the amplifying part with reference voltages respectively to generate a high level signal when the output voltage of the amplifying part is higher than the reference voltage and a low level signal when the output voltage of the amplifying part is lower than the reference voltage.
