Abstract

An experimented study of a linear induction motor whose stator is divided into short  stators that are connected in series is presented. The investigation includes a comparison of  this motor with another motor having undivided stator. The present investigation is  concerned with no-load and full-load conditions. the thrust, the power factor and the  efficiency are reported under both constant current and voltage operation measurements of  air gab flux over the length of the long stator :md the three short divided stators are also  presented. The cascade connection of three divided short stators for different distribution of  phase m.m.f. namely the same polarity distribution (N-S-N-S-N-S) and opposite polarity distribution is presented.
The experimental results recommended the cascade connection with the same distribution m.m.f. and a minimum distance between'' the stators to yield free movement and reduce the entry and exit ends power loss. The experimental study aims to demonstrate the divided short stator and to solve the problem regarding the suspension of long stator on the train to cope with sleep slope and irregularities of the track.
