する電動機回転数検出回路。 A pulse generator that sends out pulses with a frequency proportional to the rotational speed of the motor, and a motor rotational speed detection that obtains the output signal of the pulse generator and detects the pulses per unit time or the time of the pulse interval. The circuit includes a signal frequency multiplying means for multiplying the pulse output, and a first speed detecting means for counting the number of pulses per unit time of the output of the signal frequency multiplying means while the motor is rotating; 1. A motor rotation speed detection circuit comprising second speed detection means for measuring the time between two pulses after the motor starts rotating.
