Abstract

PURPOSE:To enable to digitize the controlling circuit for a motor by a method wherein the clock pulse number in proportion to a revolution speed and the counted number of clock pulse of the frequency higher than said clock pulse number are compared and the ON-OFF ratio of the load controlling element is determined at the time when the above numbers are coincided with. CONSTITUTION:The revolution speed of the motor 1 is detected by a sensor 2 and a counter 6 is inputted through the intermediary of a pulse generator 4 and a delay circuit 5. The counter 6 counts the pulse of a clock generator 7, the frequency of which was divided by a frequency divider 8 between each pulse to be inputted from the delay circuit 5, and the counted value is memorized to a latch circuit 9 for every output pulse of the pulse generator 4. Also, the second counter 11 is operated by the output pulse of the delay circuit 5 and the clock pulse before the frequency is divided is counted. The comparator 10 compares the value of the clutch circuit 9 and the counted value of the counter 11 and the ON-OFF ratio of the transistor 14 to be used for control of power supply is controlled by turning out an output to a flip-flop 13 at the time when said value are coincided with.
