Abstract
The five-phase synchronous reluctance motor is a strong contender in applications that require fault tolerance, as a motor can still run despite the loss of one or two stator phase (s). This paper presents the effect of mixed stator winding configurations and the number of rotor flux-barriers on average torque and torque ripple of five-phase transverse- laminated synchronous reluctance motors (SynRM). The five-phase stator windings are designed as four poles and distributed in 40 slots. Three different winding configurations with the same number of series conductors per phase are designed and modelled together with rotors that have two, three and four rotor flux-barriers per pole. The winding configurations consist of the conventional double layer (CDL), triple layer (TL) and the combination of double and triple layer (DTL) configuration. In total, nine SynRMs have been designed and modelled using the 2D Finite Element Method (FEM). The Finite Element Analysis results proved that the five-phase SynRMs with mixed DTL winding configurations have shown to have produced high average torque with low torque ripple content when designed with four and three flux barriers.
