Abstract

A double-sided short-stator linear induction motor excited by a sinusoidally-distributed current sheet is analyzed. The motor characteristics are computed by expressing the magnetic vector potential in terms of difference equations, digitally solving these equations for the vector potential. The performance such as forces, losses, Poynting vectors, and efficience are obtained from the vector potential. Entry, and exit, edge-effects are taken into account by formulating the appropriate boundary conditions. The results are compared with those obtained from an idealized motor excited by a sinusoidally distributed current sheet of the same magnitude.
