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