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 according to the principles described elsewhere  and the various cross sections are drawn. Both motors are analyzed with the FEMM (Finite Element Methods Magnetics) magnetic analysis programme which uses the finite element technique. The results are presented in figures using the same colour scale, to enable differences and similarities to be clearly observed.
