我开始设计一种用于测试单相交流电动机的DyNO。我知道量化RPM的2种方法：在脉冲之间的1次，以及在某个预定义周期内的2个脉冲数。问题：哪一个将给我最佳的精确度和准确度，还有第三个更好的方法吗？ 以上来自于百度翻译 以下为原文 I am starting on the design of a dyno for testing some single-phase ac motors. I know of 2 methods for quantifying the rpm: 1 - time between pulses, and 2 - count numberof pulses over some predefined period. Question: which will give me the best precision and accuracy, and is there a third perhaps better method?
