| Abstract |
While the effect of time harmonics on rotary induction drives have been reported in numerous publications in recent years, the effects of harmonics in excitation of LIMs has received comparatively little attention. The main aim of the presented paper is at the performance calculation, analysis of losses and basic concept of vector control for inverter-fed LIMs. The considerations are based on an improved equivalent circuit with the longitudinal end effect taken into account. A method of calculating the stray high-frequency losses has been worked out. The exciting current of a LIM is constant if v'''sf is controlled in proportion to the secondary current. Experimantal tests have been made to justify the results. |
