摘要
Abstract
In order to solve the problem of multiple excitation sources and their complex distribution inside the three-phase asynchronous motors, the idea of using equivalent sources to replace the real excitation sources for load identification was proposed. With the vibration output of the machine base as the target, the number and distribution of the equivalent sources were studied. The rotor bearing force and electromagnetic excitation force were retrieved based on the vibration response and verified by experiments. The results show that the equivalent sources proposed in this method can effectively reflect the effect of the real excitation sources, and the error of the identified excitation is below 5dB, meeting the requirements of engineering application.关键词
