Performance analysis of diecast multicage induction motors: a comparative study of two approaches

The paper presents a comparative study of the analysis of diecast double-cage induction motorsby single-cage/deep-bar approach and multicage-approach methods. In both the methods, saturation ofleakage flux paths and main flux paths have been considered. The performance of individual cages and saturation effects have been clearly brought out. The skin-effect ratios for the rotor, obtained by both the methods, are compared. The validity of the equations is ascertained by comparison with the experimental results.
