Sensitivity analysis of 6–19 pole outer rotor configuration of FSPM generator for wind turbine application

Flux Switching Permanent Magnet Machine (FSPM) is categorized as a newest type of machine which has the benefits of brushless permanent magnet (PM) and switched reluctance machine (SRM) simultaneously. The illustrious obtained characteristics from those mentioned machines such as fault tolerant capability, high torque and power density and simple structure provide a very bright future for FSPM in wind turbine power application. In this paper a thorough sensitivity analysis is presented. Firstly the simulation is carried out to achieve the best PM width in order to reduce the total cost while the proper electromagnetic performance of the machine is achieved. Secondly the stator and rotor teeth are changed with the specific step in a reasonable range in order to perfectly analysis the effect of them on electromagnetic force (EMF), output power and electromagnetic torque novel outer rotor configuration design of FSPM is proposed.
