ABSTRACT:
This invention is concerned in a secondary conductor for an elevator-driving linear induction motor in which, in connecting secondary conductor members to one another, adjoining portions of secondary conductor members are cut and engaged with one another by lapping them over each other, and the edge portions of them are joined at least on one side with a fastening member or by pressure joining or by welding, whereby the difficulty is eliminated that the secondary conductor members, being bent for instance, are raised to form a step therebetween, so that the secondary conductor members are brought into contact with or struck against the primary windings of the linear induction motor, and the secondary conductor members and the primary windings are damaged.
