项目摘要

The head investigator and the investigator have proposed a six-phase pole change induction motor (a six-phase PCIM) to improve the operation characteristic of a motor for driving the electric vehicle (EV), and have clarified the operational principle, the steady state characteristic and so on. Also, the analysis theory for six-phase PCIM has been proposed and is experimentally clarified that the steady state and the transient characteristics can be to calculated finely. As the result, the six-phase PCIM has excellent characteristics, such as, the expansion of constant power operation range without increase of the current and the volume of the motor, and the miniaturization of the six-phase PCIM system without mechanical contactors. Furthermore, it have been experimentally verified that the characteristics at the pole change former and later can be continuously analyzed using the proposed analysis theory. However, if the application of the six-phase PCIM in EVs is considered, then a pol … More e change condition as suppressed the large transient variation becomes necessary.The purpose of this project was to build a basis for a practical six-phase PCIM design, which includes clarifying the transient characteristics, so on. In order to realize this purpose, this project was conducted as follows;1.A prototype six-phase inverter (INV) was made.2.A system for measuring the transient characteristic was established.3.Using the six-phase INV, the experimental result were compared with simulated results.4.An evaluation method for the pole change conditions was proposed.5.The pole change condition was examined in detail.As a result, the investigators were able to propose a pole change condition that suppresses the transient phenomena and also crarified both theoretically. and experimentally that a smooth pole change operation can be pbtained. In addition, the basic data required for practical application of the six-phase PCIM in EVs was also obtained and, therefore, the purpose of this project was achieved. Less

为了改善电动汽车驱动电机的运行特性，本课题负责人和研究者提出了一种六相变极感应电机（六相PCIM），并对其工作原理、稳态特性等进行了阐述。同时，提出了六相PCIM的分析理论，并通过实验验证了其稳态和瞬态特性是可以精确计算的。结果表明，六相PCIM具有在不增加电机电流和体积的情况下扩大恒功率工作范围、无机械接触器的六相PCIM系统小型化等优良特性。实验验证了该分析理论可以连续分析变极前后的特性。然而，如果考虑到六相PCIM在电动汽车中的应用，那么就需要一个更大的变化条件来抑制大的瞬态变化。该项目的目的是为实际的六阶段PCIM设计建立基础，其中包括澄清瞬态特性等。为了实现这一目的，本项目进行了如下工作；研制了一种六相逆变器（INV）样机。建立了一套瞬态特性测量系统。采用六相INV，将实验结果与仿真结果进行了比较。提出了一种换极条件的评价方法。详细考察了换极条件。因此，研究人员能够提出一种抑制瞬态现象的极变化条件，并从理论上完善了这两种现象。实验结果表明，该方法可以获得平滑的换极操作。此外，还获得了六相PCIM在电动汽车实际应用所需的基础数据，从而达到了本项目的目的。少
