The purpose of this project is to reduce in vibration and acoustic noise of ac three-phase induction motors due to unbalanced magnetic pull by controlling inverter output currents. The results obtained are as follows :(1)An experimental motor control setup was developed. New power devices, IGBTs, were used for the power convereters. We confirmed that the setup worked successfully for our experimental purpose, but could not carry out motor drive tests due to the time limit. We are planning to continue the study using the newly developed experimental setup. A multilevel-voltage source rectifier having a three-phase diode bridge circuit as a main power circuit was also developed for the experimental setup. The rectifier has a feature of very low distorted input current waveforms.(2)The current components injected for reducing unbalanced magnetic pull caused unexpectedly large adverse effects on torque pulsation. We expect that two inverter system may solve this problem, then we will continue this project to obtain further advances.

本计画旨在借由控制逆变器输出电流，以降低交流三相感应马达因不平衡磁拉力所产生之振动及噪音。取得的主要成果如下：（1）研制了一套电机控制实验装置。新的功率器件IGBT被用于功率整流器。我们确认该设置成功地用于我们的实验目的，但由于时间限制，无法进行电机驱动测试。我们计划使用新开发的实验装置继续这项研究。一个多电平电压源整流器具有一个三相二极管桥电路作为主电源电路也开发了实验装置。该整流器具有输入电流波形畸变非常小的特点。（2）为减少不平衡磁拉力而注入的电流分量对转矩脉动产生了意想不到的大的不利影响。我们期望两个逆变器系统可以解决这个问题，然后我们将继续这个项目，以获得进一步的进展。
