Abstract

This paper proposes a methodology for numerical modelling of permanently split capacitor motor under different operating regimes with the aid of Finite Element Method (FEM). Firstly, based on the double-field revolving theory and the method of symmetrical components, all important motor parameters and characteristics are calculated. They serve as input data in FEM based model together with the exact motor geometry and the properties of all materials. The accuracy of the calculated parameters and characteristics is verified by experiments. FEM model evaluates the electro-magnetic quantities of the motor such as the magnetic flux density in motor cross-section and the magnetic field strength, often difficult to be calculated by analytical methods. The following results are obtained- the magnetic flux density in motor cross-section and the air gap under different operating regimes such as no-load,rated load and locked rotor. They are calculated for magneto-static case i.e. frequency of 0 Hz as well as for timeharmoniccase i.e. frequency of 50 Hz. The obtained results enable parts of the motor construction with high fluxdensity to be discovered and further improved by using high quality magnetic materials
