Multi-objective optimization of high torque density segmented PM consequent pole flux switching machine with flux bridge

Due to double salient structure, Flux Switching Machines (FSMs) are preferred for brushless AC high speed applications. Permanent Magnet (PM) FSMs (PM-FSMs) suited applicants where torque density (Tden) and power (Pden) the utmost requisite. However conventional PM-FSMs utilizes excessive rare earth PM volume VPM, higher cogging Tcog, ripples (Trip) comparatively lower Pden due flux leakage. To overcome aforesaid demerits, a new Segmented Consequent Pole (CP) FSM (SPMCPFSM) with bridge barrier is proposed which successfully reduces VPM by 46.52% cost 46.48%. Moreover, Multi-Objective Optimization (MOO) examines electromagnetic performance variation in geometric parameters global optimum key metric such as linkage (Φpp), harmonics (ΦTHD) average (Tavg), Trip, Tden, (Pavg) Pden. Analysis reveals that MOO improve Φpp 22.68%, boost Tavg 11.41%, enhanced Pavg 4.55% increased Tden 11.41%. Detailed comparison existing state of art shows SPMCPFSM offer maximum up 88.8%, truncate Trip 24.8%, suppress Tcog 22.74%, results 2.45 times
