Abstract

The skewing is the most commonly used technique for noise minimization in induction motors. In order to take the skewing into consideration in FEM simulations, one should design a multi-slice 2D model or a 3D model, since the skewing affects the motor design along the shaft axis. As a consequence, the complexity of the FE model increases as well as the computational time, especially when the analysis performed, takes into consideration the non-linearity of the iron core. This paper offers a technique for the skewing consideration in the induction motor, when simulated as un-skewed in transient electromagnetic 2D FEM analysis. The proposed technique could be particularly useful for faster simulations when the necessary simulation time is long, e.g. for diagnostic purposes. Experimental testing verifies the simulations' results with accuracy.
