Linear induction motor

摘要

A linear induction motor comprising an inductor with a magnetic core structure formed of first-group laminations extended in one direction and interconnected by means of second-group laminations extended in another direction transversely of the first direction and with a polyphase concentrated winding and a secondary element having an electrically conductive part arranged on a magnetically conductive base, each first-group lamination being provided with at least four slots and each second-group lamination having an inverted U-shape configuration. Each coil of the polyphase concentrated winding encompasses one of rods of at least one of the first-group laminations and one of rods of at least one of the second-group laminations. Coils in each row extended in the first direction have a forward phase rotation up to the middle of the row and a reverse phase rotation thereafter. Coils in each row extended in the second direction have a forward phase rotation. This invention provides a means for increasing safety of occupants of high-speed ground transport systems and for enhancing operational reliability of such systems.
