Motors, alternating-current; armatures.-The end rings of the short-circuited rotors of induction motors and the like are built up of sections A, Figs. 1 and 4, having toothed peripheries, these teeth a being twisted through a right-angle and fitting into saw-cuts in the conductor bars B, or into the space between the two parts of a divided bar, so as to space the end-ring sections apart and to form radial planes acting as fan blades for ventilating the machine. The teeth are attached to the conductor bars by soldering, brazing, riveting, &c., and the end rings may be further secured together by bolts e threaded through distancepieces f, and also by extending the conductor bars beyond the end rings and grooving them to receive steel binding-wires d.
