Hybrid analytical - FEM analysis of single phase Permanent Magnet Synchronous Motor

Abstract

Self-starting single-phase Permanent Magnet Synchronous Motors (PMSM) are widely accepted as low-power motors in many domestic appliances. In the paper a hybrid analytical-FEM approach for full performance analysis of a PMSM is presented. At the beginning, the magnetic circuit theory as an essential approach and Finite Element Method (FEM) as a powerful numerical approach are employed for determination of the most important parameters and steady-state characteristics. After, the calculated results are implemented in a simulation approach based on a MATLAB/Simulink environment. The final results are the dynamic characteristics, developed for variety of the motor starting conditions. On the basis of the determined characteristics, the full performance analysis, including steady-state and transient operation of the studied motor is carried out.
