A novel approach to measuring motor speed

摘要：

A new M method is used to solve the problem that the measured precision cannot be guaranteed which is caused by the less recorded numbers of the pulses in a testing time when the motor is at low speed. After analyzing the theory of the M method, the conclusion that the M method is not suitable except for the high speed is summed up. And the lower the speed is, the lower the precision is. The new M method is based on estimating the speed, will not lose the real-time of the M method at high speed and can maintain the same precision in all measuring range. The new M method is used as a good application in the motor speed measurement experiment, and the measuring precision of the new M method can reach 10 times as that of the M method.
