Abstract :
A new method to model the end-effect for single-sided short-primary linear induction motors (LIM) is developed, considering the effect of non-zero leakage inductance of the secondary. An improvement to the standard equivalent circuit model for LIM is made to include the effect of partially-filled end slots. This new equivalent circuit provides better agreement between the model predictions and the experimental results of a transit LIM. The analytical results are verified with the field test data collected from a full-scale LIM motor designed for public transit systems.
