ABSTRACT:
A method and apparatus for measuring a motor speed in which a measurement pulse train is formed from a measurement signal generated in a frequency generator coupled to the rotation of a motor, and a reference pulse train is formed with a frequency greater than that of the measurement pulse train, and the number of both pulses are counted for a predetermined sampling time, and both count values are compared, thereby measuring the motor speed. Accordingly, the rotation speed can be measured by a single algorithm regardless of the variation of the motor speed, and the measurement time and the measurement error can be greatly decreased. Furthermore, the continuous speed controlling over the whole speed range is possible.
