电动机转矩波动测量方法研究

The Research of the Measurement Method for Motor Torque Fluctuation

转矩波动系数是描述电动机运行平稳性的技术指标。为了精确测量电动机的转矩波动,该文从转矩波动系数的定义出发,推导出一种全新的转矩波动测量原理,并在此基础上给出了转矩波动系数的测量方法。该方法克服了传统测量方法测量不准确和难以测量的问题。

The coefficient of motor torque fluctuation is a technical parameter for describing stationarity of motor running. To accurately measure motor torque fluctuation, this article proceeds from the definition of motor torque fluctuation, and infers a bran--new philosophy of measurement for motor torque fluctuation. On this foundation, it gives a measurement method for the coefficient of motor torque fluctuation. This method solves problems of inaccurate measurement and measurement difficulties for classical approach.
