Abstract :

Comparative study of loss and inductance features of different permanent magnet synchronous machine topologies are presented in this paper. Moreover, the efficiency characteristics of the compared machines are also given. The results show that the machine having twelve stator poles and eleven rotor poles i.e. PS-SFPM 12/11 has very large amount of total core loss, which would eventually reduce the overall efficiency of the machine. Moreover, it has the largest value of mutual inductance which is an undesirable quality for fault-tolerant applications. It is also observed that, the machine type having E-core stator structures exhibit the lowest amount of permanent magnet eddy current losses and total core losses. Essentially, the investigated machine having single-stator configurations have higher self-inductance and lower mutual-inductance values, relative to the other compared machines. Keywords: Double-stator; inductance; loss; machines; and single-stator.
