A theoretical analysis of linear induction motors

This paper describes a quasi-three-dimensional mathematical model developed for the design of linear induction motors operating with either controlled current or controlled voltage supplies. The model is notable in its simultaneous treatment of (1) electromagnetic boundary phenomena, including longitudinal end-effect and transverse edge-effect; and (2) other refinements, such as the effects of staggered double-layered windings, and a secondary resistance corresponding to the actual current pattern. The mutual interaction of these characteristics is encompassed in the model. Motor performance predictions obtained from the model have agreed with full-scale hardware test results
