摘要：

The longitudinal end effect in a linear induction motor (LIM) is analyzed assuming two travelling magnetic flux density waves in the airgap: the wave travelling with synchronous velocity and the wave representing end effect. A simple equation for the end-effect factor which modifies the airgap EMF is obtained, and a simple equivalent circuit incorporating the end-effect factor is established. Analysis is compared with measurements from two large-scale single-sided LIMs. The equation for the end-effect factor is sufficiently accurate to be used for design studies of LIMs. Since end effects are negligible at low speeds, the end-effect factor has application for medium- and high-speed LIMs.
