Linear induction motor

A linear induction motor comprising:

• an inductor;
• a magnetic core structure of said inductor;
• laminations of a first group of said magnetic core structure of said inductor extended at right angles to the direction of movement of said inductor;
• a yoke of each of said first-group laminations of said magnetic core structure of said inductor;
• rods of each said first-group lamination of said magnetic core structure of said inductor interconnected by means of said yoke of each of said first-group laminations of said magnetic core structure of said inductor;
• each of said first-group laminations of said magnetic core structure of said inductor having n slots;
• laminations of a second group of said magnetic core structure of said inductor extended in the direction of movement of said inductor;
• a yoke of each said second-group lamition of said magnetic core structure of said inductor;
• rods of each said second-group lamination of said magnetic core structure of said inductor interconnected by means of said yoke of each of said second-group laminations of said magnetic core structure of said inductor;
• slots in each said second-group lamination of said magnetic core structure of said inductor;
• said first-group laminations of said magnetic core structure of said inductor interconnected by means of said second-group laminations of said magnetic core structure of said inductor;
• one of said extreme first-group laminations of said magnetic core structure of said inductor having its rods adjacent all the extreme rods of said second-group laminations of said magnetic core structure of said inductor, arranged in mating relation the said first-mentioned rods;
• said rods of the other first-group laminations of said magnetic core structure of said inductor fitting tightly in said slots of said second-group laminations of said magnetic core structure of said inductor so that no gaps exist therebetween and toothless active zones are formed in the direction of movement of said inductor;
• said yokes of said first-group laminations of said magnetic core structure of said inductor so arranged with respect to said yokes of said second-group laminations of said magnetic core structure of said inductor that appropriate gaps exist therebetween;
• a polyphase winding of said inductor;
• coils of said polyphase concentrated winding of said inductor arranged in a plurality of rows;
• a first group and a second group of said coils of said polyphase concentrated winding of said inductor;
• said first-group coils of said polyphase concentrated winding of said inductor arranged on said yoke of each said first-group lamination of said magnetic core structure of said inductor, and equal in number to said slots in each said first-group lamination of said magnetic core structure of said inductor;
• said second-group coils comprised in said polyphase concentrated winding of said inductor arranged on said yoke of each said second-group lamination of said magnetic core structure of said inductor and equal in number to said slots in each said second-group lamination of said core structure of said inductor;
• a secondary element with respect to which said inductor moves;
• a magnetically conductive base of said secondary element;
• an electrically conductive part of said secondary element arranged on said magnetically conductive base of said secondary element.
