End Effect in Short Secondary Linear Induction Motors

James L. Kirtley, Andrew P. Johnson
2006

One of the reasons linear motors, a technology nearly a century old, have not been adopted for a large number of linear motion applications is that they have historically had poor efficiencies. This is due to the open-ended geometry of a linear motor, and has restricted the progress of linear motor development [1], [2], [3], [4]. The end effect is a direct consequence of this open-ended geometry. This paper will address the issue of whether or not the end effect phenomenon of a short secondary Linear Induction Motor (LIM) could be responsible for any reduction in average thrust and consequently, a reduction in motor efficiency.
