The study involves the use of MATLAB to simulate 50kW, 3-phase, 415V, 50Hz, 6 poles induction machine. Based on the variation of the magnetic and electric loading of the machine, the various design values of the rotor and stator of the machine are specified. The performance index which includes stator loss, rotor loss, cost, power factor, efficiency, and torque are also specified for squirrel cage induction motor (SCIM) Keyword: MATLAB, stator, rotor, magnetic loading, electric loading, SCIM. axial current per meter of circumference of the rotor I. INTRODUCTION [3]. Generally, all rotating electrical machines work by the interaction of the magnetic field set up in Advantages of higher value of B include lower stator and rotor windings of the machines to convert size of the machine, decrease in cost of the machine, mechanical energy into elec
