とを特徴とする回転数測定回路。[Claims for Utility Model Registration] The rotation speed of the motor to be measured is detected in a non-contact manner by a rotation speed detection sensor using optical or magnetic means, and the rotation speed of the motor is detected from a pulse signal proportional to the detected motor rotation speed. In the rotation speed measuring circuit that measures the rotation speed, the time interval between two adjacent pulses of the pulse signal detected by the sensor is measured by a counter and a latch, and the measured value is divided at each time point by a D/A converter and an analog divider. A rotation speed measuring circuit characterized by converting the rotation speed into the rotation speed.
