のかご形回転子。 In a squirrel-cage rotor for an induction machine, the ends of a large number of conductors passing through the rotor core are welded to an end ring, and a reinforcing ring is provided to suppress displacement of the end ring in the radial direction due to centrifugal force.
An insertion hole into which the end of the conductor is inserted is provided in the end ring, and the cross-sectional dimension of the insertion hole at an appropriate length on the rotor core side is formed to be larger than the cross-sectional dimension of the conductor by an appropriate amount. A squirrel-cage rotor for an induction machine, characterized in that the end ring is brought into contact with the end face of the rotor core, and the end of the conductor is welded to the end ring at a non-expanded portion of the insertion hole.
