The paper initially reviews some previous work with respect to the effect of inter-bar currents on the performance of a cage induction machine with a skewed rotor. A multi-sliced nonlinear 2D finite element model is then put forward to account for this current. This model uses different circuits to assess how the inter-bar 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 simulation results are compared to measured results and it is verified that the inter-bar currents do have an effect that is not normally accounted for in standard modeling techniques.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
