Abstract

Nowadays, permanent magnet machines are being popular in the industries due to its higher efficiency compared to conventional electric motors. This paper presents the modeling and simulation of three and five phase permanent magnet synchronous motor machine for healthy as well as open phase fault condition. In this paper, the crucial performance of the system has been analyzed before failure and after failure. The after effect of failures might result in costly damage and lead to another fault, if nothing is planned earlier for this fault protection. This undesirable situation ought to be averted, or at least there may be a fault tolerant function to deal with such failures. Therefore, a control scheme under an open or multiple phase fault has been discussed in this paper for multi-phase PMSM drive with sinusoidal back EMFs. In the three phase system, one phase has been kept open, whereas for five phase system, two phases kept open one by one for analysis purpose. The fault has been created only for some instant of time, after occurring fault, the PI controller compensated phase faults. Finally, it has been observed that the multi-phase machines have higher fault tolerant capability.
