摘要
介绍了频率法、周期法转速测量的基本原理，综合两种测速方法的优点，根据不同的转速范围，选用不同的测量参数，提出一种可以实现快速、有效、高精度的测速方法。方便采用单片机实现。
The principle of the methods of motor-rotafng-speed measuring based in frequency and cycle is introduced in this paper. And a fleetly, effective, high-precise method of motor-rOtating-speed measuring is Studied through integrating the merits of both methods. Using this method, variable measuring-parameter can be selected according to the range of rotating-speed, so that this method can be implemented through singlechip.
