Measurement of Induction Motor Torque Pulsations Due to Inverter Supply,tself. This paper reports the results of a new method for measuring the electromagnetic torque directly from air gap flux and stator flux measurements [3]. In particular, the measurement technique utilizes the coils of the motor itself as the flux sensing coils so that extra “search coils” are not required [4],[5].作者: membrane 時(shí)間: 2025-3-22 18:48 作者: 使人煩燥 時(shí)間: 2025-3-23 00:46

Measurement of Induction Motor Torque Pulsations Due to Inverter Supply,ning systems. In such applications audible noise is produced by the inherent torque pulsations of such systems caused by the rectangular impressed voltages and currents.

Some Methods for the Reduction of Electromagnetically Excited Vibrations and Noise in Induction MacThe problems of electromagnetically excited vibrations and noise have been studied actively for many years and yet machines are still manufactured which produce excessive vibration or “magnetic” noise. There are also some well-known examples of applications for which it is vital to have very low levels of both these undesirable effects.作者: anus928 時(shí)間: 2025-3-26 09:32
