Abstract
Permanent magnet (PM) machines have been widely employed in electric vehicles, wind power generators, domestic appliances, and industrial servos etc. When the rotor is eccentric, either static or dynamic due to manufacturing or operating tolerances, the full machine model is necessary for finite element analysis (FEA), because the model cannot be simplified by utilizing the periodicity any more. This is problematic and time-consuming for FEA especially when the slot number and pole number are high, such as in direct-drive low-speed PM machines. This paper proposes a new analytical model which combines the superposition method and the subdomain method [1] for predicting air-gap field in PM machines with rotor eccentricity.
