This paper describes a useful method to analyze the nonlinear magnetic fields in a condenser motor considering skewed slot effects by 2-D FEM coupled problems. In this method, the exciting circuit equations, the rotor circuit equations including the currents in the end ring and the magnetic field equations are solved simultaneously. Therefore the input currents, the rotor bar currents and the currents in the end ring are obtained directly. Moreover this method is developed to colisider the skewed slot effects by modifying the rotor circuits. The validity of this method is showii by comparison between the computed results and measured ones.

“…It is why previous research by a wide range of authors has been considered on the concept that current does not flow into a broken bar. Nevertheless, in die-cast aluminium cage, an electrical contact exists between the bars and the iron core [5][6][7][8][9][10][11][12]. Therefore, when a bar is broken, the current continues to flow into it knowing that interbar currents depend on the evolution of the defective bar.…”

Abstract:The paper presents the special software for transient FE analysis of coupled electromagnetic-thermal problems in a squirrel cage submerged motor working at cryogenic temperature. A time-stepping finite element method and transients analysis of an induction motor has been applied. The non-linearity of the magnetic circuit, the movement of the rotor, skewed slots, and the influence of temperature on electric and thermal properties of the materials has been taken into account. Developed on the basis of presented algorithm a computer program used to analyze the phenomenon of current displacement in the rotor bars of high-voltage cage induction motor working in cryogenic conditions. The results of the simulations are presented.
