Abstract
This paper presents the performance of threephase
induction motor with a stator winding comprising of a
combination of double and triple layer arrangements in slots,
here simply referred to as double-triple stator winding layouts.
The proposed layout provides a three-phase induction motor
with high torque density and greater efficiency than the
conventional machine with double winding layout. Field
analysis technique is used to show that this winding
arrangement has improved harmonic content and the machine
performance is computed using Finite Element Method
(FEM). Saturation is accounted for in the computation of the
inductances. A 1500 W conventional three-phase induction
machine with 36 stator slots is first wound as a four-pole
double layer and then as a four-pole double-triple layer for the
experimental study. Both windings are chorded with one slot
with same number of turns per phase and use the same
squirrel cage rotor.
