Abstract
A motor control circuit includes: a detector outputting a detection signal in accordance with the motor rpm; a counter counting the number of clocks in accordance with a rotational cycle represented by the detection signal; a controller counting a DC motor based on the count value; and a divider dividing a frequency of a basic clock based on a preset division value to generate a counting clock. The divider generates a counting clock having a frequency corresponding to a rotational cycle, and the counter counts the number of counting clocks.
