Abstract :
Taking a two-pole high-speed permanent magnetic synchronous generator (PMSG) as an example, the mathematic and physical models with generator eccentric are established. This paper presented two different methods to calculate the magnetic field distribution and unilateral magnetic force (UMF) in the whole calculating region. And then analysis of influences of the eccentricity, load current and harmonics on the UMF have been undertaken. Finally, variation of UMF with the eccentricity is presented.
