Abstract
Some advantages of rotor slot asymmetry are presented. The study was made using a computerized model of the two and four pole turbo-generator magnetic field based on the principle of magnetic vector potential and finite differences including nonlinearities of magnetic material. Rotor asymmetry reduces the peak value of mid gap flux density and saturation in the stator teeth.
