Abstract
Among the components of induction motors, the end ring is needed to connect rotor bars electrically. Some approaches to calculating its resistance employ equivalent circuit methods, but they are not accurate because they assume ideal sinusoidal current distribution. This paper presents a method to calculate the current distribution in the end ring by the finite-element method (FEM). This paper uses both two-dimensional (2-D) A-/spl Phi/ FEM analysis and three-dimensional (3-D) T-/spl Omega/ FEM analysis. The magnetic flux density is obtained from 2-D analysis, and the electric vector potential is obtained from 3-D analysis. With these results, the current distribution in the end ring is calculated and the proper size of the end ring is selected by solving some case problems.
