Design and Development of Three Stator 343 power consumed due to eddy currents, copper losses and poor power factor are considerably reduced [11]. The efficiency of an induction motors ranges between 0.75 and 22 kW can be improved by means of die cast copper instead of aluminium cage rotor with premium steel core [12]. Induction Motors Notes - ssmengg.edu.in Stator of an induction motor consists of stator core and stator slots. Stator slots: in general two types of stator slots are employed in induction motors viz, open clots and semiclosed slots. Operating performance of the induction motors depends upon the shape of the slots and hence it is important to select suitable slot for the stator slots. High Frequency Losses in Induction Motors - NASA ltigh Frequency Losses in Induction Motors-Summary Methods for reducing the surface losses include reducing the stator slot opening, using more stator slots, enlarging the air gap and using low loss, thin laminations in the rotor core. Stator slot magnetic wedges have also been shown to be very effective. DESIGN OF TRANSFORMER Stator slots: in general two types of stator slots are employed in induction motors viz, open slots and semi closed slots. Operating performance of the induction motors depends upon the shape of the slots (i) Open slots: In this type of slots the slot opening will be equal to that of the width of the slots.

Abstract: This paper proposes optimal design method of stator slot for three-phase cage induction motor fed by six-step inverter output voltage by using proposed analysis method. The finite-element method (FEM) on one phase band stator periodic condition is coupled with harmonic equivalent circuit. Using the FEM, the stator slot is optimally designed and the result is presented.
