Abstract

The operational behavior of a six-phase, 2 poles and 36 stator slot squirrel cage induction machine is analyzed for the effects of stator slot openings in this paper. The study is carried out using the field analysis method and the finite element analysis (FEA) of the two dimensional commercially available finite element QuickField modeling Package. Experimental analysis is conducted on a 1.5 kW machine to validate the integrity of the theoretical method of the original opening slot. The FEA analysis is carried out for no-load (Magnetostatics) and loaded conditions (steady state AC Magnetics). The results show that decreasing the slot opening of the stator winding increases the performance of the machine.
