Electromagnetic flux analysis on a new outer-rotor hybrid excitation flux switching machine

摘要

This paper presents an analysis of electromagneticflux capability on a new 12Slot-14Pole outer-rotor hybridexcitation flux switching machine (ORHEFSM). In this proposedmachine, all the magnetic flux sources are placed on the statorresulting for robust machine and suitable for high speedapplication. Moreover, coil test analysis, permanent magnet(PM) and DC field excitation coil (FEC) flux characteristic, fluxinteraction between DC FEC and armature coil, flux distribution,and torque characteristics are also investigated. The results showthat the torque performance of the proposed machine isproportional to the change of flux linkage. Therefore, a fluxcontrol capability of the machine gives additional advantage forvariable speed condition application.
