A Novel Approach to Performance Characteristics Evaluation of a Shaded-Pole Induction Motor

In the paper a novel approach to the modeling and simulation of shaded-pole induction motor, aiming towards the evaluation of its performance characteristics at different load condition is presented. for this purpose, different methods for analysis, an analytic Circuit Theory Method (CTM), numerical Finite Element Method (FEM) and simulation Matlab/Simulink (MSM) are applied. The proposed approach is valid for both the steady-state and transient regimes. A complex modeling of the shaded-pole induction motor, in order to derive the most suitable models for application of proposed methods, is carried out. On the basis of the analysis of the performance characteristics, each of the methods is going to be evaluated. The results of analytic and numerical calculations, as well as simulations, are compared with experimentally obtained ones, and/or with know values given by the producer; they shown reasonable agreement, proving the proposed approcah as accurate
