OPTIMIZATION EFFICIENCY OF SLITTED-CORE INDUCTION MOTOR

Asim Gökhan Yetgin – Mustafa Turan

   In this study, a 3kW squirrel cage induction motor having slits in stator and rotor teeth were examined. The slit depth and width in the 56 different slitted motor models were optimized with Finite Element Method Magnetics (FEMM) software by using Finite Elements Method (FEM). What value the depth and width of optimum slit should be was determined in order to obtain maximum motor efficiency in the new motor models created with the proposed slitted structure, and how the depth and width of slit could affect the performance of motor was demonstrated.

Keywords: induction motor, slit optimization, speed-efficiency characteristic
