Description
Summary:This paper initially reviews some previous work with respect to the effect of interbar currents on the performance of a cage induction machine with a skewed rotor. A multisliced nonlinear 2-D finite-element model is then put forward to account for this current. This model uses different circuits to assess how the interbar current should be incorporated into the simulation. It uses different arrangements in both the axial and radial representations. The starting characteristics are focused upon, and the simulation results are compared to measured results. It is verified that the interbar currents do have an effect that is not normally accounted for in standard modeling techniques.
