Abstract
A linear induction motor system employs a driven reactive element that is oppositely influenced by a pair of spaced apart devices extending along a predetermined path. By altering the relationship between the reactive elements and devices, the net driving force on the driven element is varied so that a desired velocity profile can be established, and stable index positions can be defined. The principle is advantageously used in controlling a series of independent carts in a material conveyor system, in an arrangement which incorporates secondary positional control device along the cart path, and probe means for inhibiting interference between successive carts.
