Abstract :
Based on literature, a three-phase 12S-10P Field Excitation Flux switching Machine with overlap windings between armature and FEC has been developed. However the design motor has a problem of high end coil which increase the size of the motor as well as copper losses. In this paper, a single-phase 12S-6P FEFSM with adjacent armature and FEC is introduced, which permanently eliminate the end coils problem. Furthermore the operating principle of the proposed single-phase 12S-6P FEFSM with segmental and nonsegmental rotor are investigated. Then finite element analysis is used to validate the flux distribution, induced voltage, torque, speed and power characteristics. Finally, 12S-6P FEFSM with segmental rotor can be designed for high density air-conditioner with 1kW power, 1.8Nm torque and corresponding speed of 4977r/min.
