Abstract :
Fourier-transform theory is used to solve the longitudinal-edge-effect problem in linear induction motors, for constant-current conditions. Inversion of the Fourier transform is obviated by employing Parseval´s theorem; calculations are thus considerably simplified. Experimental confirmation is given, together with an approximate method for sketching the thrust/slip curve. The ratio (goodness factor/pole pairs) is shown to be important.
