Demenko, Andrzej; Nowak, Lech Finite element analysis of saturation effects in a squirrel cage electrical machine. (English) Zbl 0862.65087 COMPEL 15, No. 4, 88-95 (1996). Summary: The paper presents a method for the finite element (FE) analysis of saturation effects in a squirrel-cage electrical machine. The proposed mathematical model includes the FE equations of the electromagnetic field, the equations which define the connection of windings, and the mechanical equation. It applies an approach based on a simultaneous solution of these equations, paying special attention to the movement simulation and applies the time-stepping method with a fixed grid, independent of the rotar position. In the method the motional effects are simulated by trigonometric interpolation of the results for the previous time step.
