ABSTRACT:
A linear induction motor comprising an inductor formed of a laminated core structure with slots adapted to receive a polyphase winding. It also comprises a secondary element with respect to which the inductor moves. The secondary element includes an electrically conductive part arranged on a magnetically conductive base. Each lamination transversely of inductor movement has an inverted U-shaped configuration and a varying height and width so that a larger lamination encompasses a smaller lamination.
