Investigation of Internal Faults for a Direct-Driven PMSG with Maxwell

The electro-magnetic torque and current are analyzed for a static eccentric PMSG. The characteristics of air-gap magnetic field, EMF, current and electro-magnetic torque of the direct driven PMSG for wind power generation are investigated with Maxwell software various eccentric conditions. The related electrical magnetic torque and current variation are achieved, especially the harmonics for current and torque.
