Abstract

This paper investigates a driving method for a Permanent Magnet (PM) Synchronous six-phase machine by using its consecutive three phases. The torque of PM synchronous machine is the division of instantaneous power (I-power) of the machine to the rotor speed. The I-power of a machine gives information about the torque. The torque output of a PM synchronous machine can be predicted by looking at the I-power. This study investigates the torque of a PM synchronous six-phase machine by exciting its phase coils for the combination of conventional three-phase, double conventional three-phase, consecutive three phases of six-phase machine and double consecutive three phases of six-phase machine. This paper also investigates the way of driving a six-phase machine using the balanced three-phase supply. Firstly, analytical studies have been done for these exciting combinations. These analytical results indicate that symmetric six-phase machine can be driven using these combinations. Secondly, a PM synchronous six-phase machine has been designed in a finite element analysis (FEA) software. Lastly, that designed six-phase machine excited with these combinations to observe the torque wave form of the machine. As a result of this study, a symmetric six-phase machine can be run by its consecutive three phases without torque ripple.

Simetrik Sürekli Mıknatıslı Senkron Altı Fazlı bir Makinenin Ardışık Üç Fazının Kullanılarak Sürülmesi

Abstract

Bu makale, sürekli mıknatıslı (PM) senkron altı fazlı bir makinenin ardışık üç fazının kullanılarak sürülmesi yöntemini araştırmaktadır. PM senkron makinenin torku, makinenin anlık gücünün (I-power) rotor hızına bölünmesidir. Bir makinede I-power tork hakkında bilgi verir. PM senkron makinenin tork çıkışı I-power dalga formuna bakılarak tahmin edilebilir. Bu çalışma, PM senkron altı fazlı bir makinenin, iki üç fazlı makinenin enerjilendirilmesi, altı faz dengeli kaynak ile enerjilendirilmesi ve bunlara ek olarak ardışık üç fazdan oluşan makinelerin enerjilendirilmesinin torka etkisini araştırmaktadır.Bu makale aynı zamanda dengeli üç fazlı beslemeyi kullanarak altı fazlı bir makineyi çalıştırılmasını da araştırıyor. Bu enerjilendirme durumları için öncelikle matematiksel analizler yapıldı. Bu analitik sonuçlar, simetrik altı fazlı makinenin bu kombinasyonlar kullanılarak sürülebileceğini göstermektedir. İkinci olarak, sonlu elemanlar analizi (FEA) yazılımında PM senkron altı fazlı bir makine tasarlanmıştır. Son olarak tasarlanan altı fazlı makine bu kombinasyonlarla enerjilendirilerek makinenin tork dalga formu gözlemlendi. Bu çalışmanın sonucunda, simetrik altı fazlı bir makinenin ardışık üç fazı ile tork dalgalanması olmadan çalıştırılabileceği görülmüştür.
