Comparative study of partitioned stator permanent magnet tubular machines with different winding configurations

الملخص EN

In this study, partitioned stator permanent magnet (PS-PM) tubular machines having single- and double-layer windings layouts have been investigated.

Two configurations of PS-PM tubular machines were considered, i.e.

partitioned stator surface mounted permanent magnet (PS-SPM) and interior permanent magnet (PS-IPM) tubular machines.

A comprehensive comparison has been carried out in order to investigate the impact of the winding layouts on such machines.

It should be mentioned that the FE package that is used in this paper is (ANSYS Maxwell).

It has been noted that irrespective of machines configurations, i.e.

either PS-SPM or PS-IPM tubular machines, similar thrust force capability, higher average thrust force per magnet volume, lower thrust force ripple as well as cogging force and higher fault tolerance capability can be delivered by PS-PM tubular machines with single-layer winding compared to that with double-layer winding.
