Abstract

In this paper, measurements of the magnetic flux in a permanent magnet synchronous machine (PMSM) with non- overlapping concentrated windings are analyzed. Flux leakage, inductances and stator iron losses are investigated from measurements performed at open-circuit, blocked-rotor, and load conditions, respectively. Comparisons of the measurements with the corresponding 3D finite-element (FE) simulations allow validating thoroughly the FE model. The zigzag leakage flux flowing from one magnet to another through a tooth tip, which is characteristic for PMSMs with concentrated windings, is highlighted and its effect on the stator iron losses is investigated.
