This paper presents the computation of the effect of rotor skewing in induction machines. Two cases of rotors with an identical number of bars but different skewing angles (0 and 10.23 degrees) are compared. This analysis is based on results obtained from measurements on a skewed rotor bars induction machine; results computed using a 2D (non skewed model) simulations; and results computed using a skewed model simulation. A new application called SKEW, neither to 2D nor 3D, has been developed and implemented in a commercial FEM software. Two approaches were considered in developing the application SKEW: the N-slice model and the extruded model.
