ABSTRACT:
The core of the secondary for use in a linear or other induction motor is a ladder-like stamping with two spaced apart rails and a number of bars extending between and having end portions of one piece with the rails. The bars of the cage can be inserted into the recesses of a core, and such recesses can be provided in one side or in two opposite sides of the core. Each recess can receive a single bar or the bars of two or more discrete cores. The bars can be confined in their recesses by slidable closures or by plugs of a hardened adhesive, a synthetic resin or an impregnating agent.
