Influence of design parameter on output torque of inset type flux reversal machine

Due to high efficiency and high power density, permanent magnet (PM) electric machines have been developed and widely accepted for industrial and vehicular applications. Flux reversal machine (FRM) is getting attention for last two decade. It has both permanent magnets and concentrated windings in its stator with reverse PM flux linkage. It can operate in both motoring and generating modes. Its simple structure makes it cost effective and suitable for mass production. However it has few drawbacks such as high cogging torque, notable PM flux linkage. To overcome this drawback FRM with an inset type permanent magnet has been introduce. My work consisted in carrying out the influence of design parameters of an inset type flux reversal machine for maximum output torque has been investigated by finite element analyses. These parameters include the stator back-iron thickness, the stator tooth width, the rotor pole arc, the rotor back iron thickness, and the rotor pole height. The outcome of my can be used for design inset type FRM based on the application such as wind power generation, aircraft and automotive.
