Flux switching machines (FSM) falls into advance category of synchronous machines having benefits of both switch reluctance and permanent magnet (PM) synchronous motor. Although, lack of PM on the rotor have numerous advantages in terms of simplicity of construction and robustness, but rotational field magneto motive force MMF cannot generate by their rotor as a trade-off, which is the base of field oriented control (FOC) in synchronous motors. Instead, these machines works on the principle of flux switching which made the FOC application in FSM significantly complex. But with the variation in rotor position, flux linkage in the phase also varies sinusoidally. By considering this phenomenon, this paper present a mechanism to implement FOC based on sine pulse width modulation (SPWM) technic for single phase 12S-6P field excited FSM. Experimental results verified successful implementation of the algorithm on the designed prototype of FEFSM. Additionally, performance wise, proposed algorithm shows considerable performance boost in terms of current consumption and torque generation.

Abstract
Flux switching machines (FSM) falls into advance category of synchronous machines having benefits of both switch reluctance and permanent magnet (PM) synchronous motor. Although, lack of PM on the rotor have numerous advantages in terms of simplicity of construction and robustness, but rotational field magneto motive force MMF cannot generate by their rotor as a trade-off, which is the base of field oriented control (FOC) in synchronous motors. Instead, these machines works on the principle of flux switching which made the FOC application in FSM significantly complex. But with the variation in rotor position, flux linkage in the phase also varies sinusoidally. By considering this phenomenon, this paper present a mechanism to implement FOC based on sine pulse width modulation (SPWM) technic for single phase 12S-6P field excited FSM. Experimental results verified successful implementation of the algorithm on the designed prototype of FEFSM. Additionally, performance wise, proposed algorithm shows considerable performance boost in terms of current consumption and torque generation.
