Abstract :
This work uses a methodology based on the 2D-finite elements method (FEM) and on circuit theory (independent currents method) to calculate the inter-bar currents and analyze their effect on the performance of the polyphase cage induction motors. The circuit theory is used to couple the rotor circuit equations to the field equations. The multi-slice technique is used to consider the skew effect
