Claims

[Claims for Utility Model Registration] 1. A squirrel cage induction comprising a conductive rotor bar housed in an axial slot of a rotor core, and an end ring connected to an end of the rotor bar. A squirrel-shaped induction motor in which the end ring is comprised of an annular conductive member and a non-conductive member having excellent heat conduction and high heat resistance, which is fixed to the conductive member. 2. The squirrel cage induction motor according to claim 1, wherein the non-conductive member is fixed to at least one of the outer periphery or the outer surface of the conductive member. 3. The squirrel cage induction motor according to claim 1, wherein the non-conductive member is inserted into and fixed to a recess provided on the outer peripheral surface of the conductive member.
