ATTRACTION/REPULSION FORCES IN A SINGLE-SIDED LINEAR INDUCTION MOTOR
Calculations of the normal force-to-thrust force ratio are made for some simple one-dimensional LIM secondary models, (i.e., effects of finite geometry are not considered). The principal result is the determination of the cross-over when the normal force changes from being attractive to being repulsive. At this point, one-sided LIMs begin aiding the guidance/support system instead of opposing it. The results indicate that for a single-sided LIM similar to the TACRV/ADLIM, the normal force is repulsive for almost the entire operating range. This is less true for a low-speed LIM. (DOT abstract)
