Abstract

This study assesses the impact of alterations in rotor slot width on the performance of a squirrel cage induction motor. Despite the widespread use of induction motors in various industries due to their simple structure, designing them accurately remains a challenge. Many design algorithms rely on analytical equations, which often fall short in providing precise results for factors like leakage fluxes and the effects of magnetic saturation. To address this limitation, finite element methods have been employed for improved accuracy, but their drawback lies in their time-consuming nature, making them impractical for use in design algorithms with optimization components. Consequently, there is a need to establish practical experimental guidelines that designers can incorporate into analytical design algorithms for obtaining satisfactory results swiftly. This paper specifically evaluates motor performance by varying the width of the rotor slot opening from fully closed to fully open, presenting valuable results to enhance design algorithms.
