An improved computational technique of the inductance parameters of reluctance augmented shaded-pole motors using finite element method

An improved technique for calculating the inductance parameters of reluctance augmented shaded-pole motors, including the saturation effect, is described. The method is based mainly on the use of finite element (FE) field calculation and partly on some analytical derivations. Equations are provided for saturated inductance components in terms of relevant winding currents, in order to facilitate the inclusion of the saturation effect into the performance evaluation. The computed values of several inductances are compared with their measured counterparts for verification.<
