Abstract
The multi-phase wound field flux switching (WFFS) machines achieved the advantages of the conventional FSPM machines and the common merits of multi-phase machines, e.g., low torque pulsations, high torque density and high fault tolerant capability. The non-overlapping windings can be used to minimize the consumption of copper and manufacturing costs for the WFFS machines. Hence, in this paper, five phase WFFS machines having the non-overlapping winding topology with four different rotor poles is presented. Ten slots with four different rotor pole designs namely 10S-12P, 10S-11P, 10S-9P, and 10S-8P are chosen to analyze the rotor pole study. The main section explains an essential overview of load and no-load analyses for five Phase WFFS machines and designs with different rotor poles are briefly compared. The proposed machine design studies are analyzed with five phase behavior of machine based on 2D-FEA. A detailed analysis of the proposed designs is also discussed like flux linkage, cogging torque, back EMF, THD, average torque versus current density, instantaneous torque, average torque versus stack length, copper losses, iron losses, efficiency and inductance calculations. The simulated results elaborate that the design with 11 rotor poles is best as it produces better back emf, higher torque and efficiency of 3.2 V, 1.65 Nm and 82.4% respectively.
