This paper complements others by the same authors [1], [2], where the general concepts, design calculations and constructional differences of an induction motor with a novel winding arrangement were presented, together with a magnetic analysis. In the present paper, the equivalent circuit for the space harmonics of the mmf is described and the slips and equivalent circuit parameters for each space...
In the companion papers, the reduction in the space harmonic effects resulting from constructional changes and new design concepts were explained. In this paper, an induction motor with a novel winding and stator structure and a standard squirrel cage motor are compared, both magnetically and in terms of their operational and constructional data. Calculations for the design of both motors are performed...
Only constructional changes can be used to reduce the negative effects of space harmonics in an electrical machine. In this paper it is shown that eliminating space harmonics by designing a phase winding placed in various shapes of slots and teeth is possible. The analysis is performed for two poles and the results can be extended to any number of poles by converting the angle from geometric to electrical...
