The theoretical analysis, the method of calculation and the experimental tests on a double-sided linear induction motor (DLIM) with squirrel-cage secondary member are given. The air-core secondary is elastic and consists of copper bars, a braided conductive lines as end rings and woven plastics filaments. Equations of two-dimensional and one-dimensional magnetic-flux-density distribution in the secondary and the airgap are derived. Formulas for resistance and reactance of the squirrel-cage secondary and the thrust of DLIM are obtained. The end effect caused by the open-endedness of the airgap is taken into account. Performance characteristics, i.e. no-load and short-circuit curves obtained from calculations and measurements, are compared.
