Estimation of losses and efficiency of double-stator switched flux permanent magnet machines

Losses such as rotor iron and stator losses, magnet eddy current loss, well efficiency of a double permanent machine having varying pole numbers is estimated presented in this study. This investigation would be vital for electrical designers quantifying the amount losses various sections given electric provide better insight on resulting output machine. Time-stepping finite element analysis (TS-FEA) procedure adopted calculations using ANSYS-MAXWELL simulation software. The compared machines same teeth/pole number (Ps) different (Pr) are designated as: 6Ps/10Pr, 6Ps/11Pr, 6Ps/13Pr 6Ps/14Pr. predicted total loss values at rated operating base speed 13.02 Watts, 13.13 13.539 13.537 from 6Ps/14Pr types, respectively. corresponding types working conditions is: 81.76%, 88.17%, 86.95% 78.61%, results show that magnitude largely depend upon factors poles hence, machine’s speed, loading angular position machine, etc. It also found waveform cycles (Nc) an revolution investigated its arrangements. most performing ones have 11- 13-rotor numbers, while least obtained type has 14-rotor number. Above all, 6Ps/10Pr characterized with high pulsations or ripples detrimental to overall performance machines.
