<p><P>PROBLEM TO BE SOLVED: To provide a rotor of a motor capable of reducing the stress amplitude of a load stress applied to a short circuit ring by the activation and stop of the motor. <P>SOLUTION: The rotor of a motor includes: a cylindrical iron core part 3; a conductor bar 4 disposed at a fixed interval in a circumferential direction inside the iron core part 3; a short circuit ring 5 connected to the conductor bar 4 and disposed on both end faces of the iron core part 3; and a reinforcement ring 6 whose outer diameter is larger than an inner diameter of the short circuit ring 5. The reinforcement ring 6 is shrink-fitted to an inner peripheral part of the short circuit ring 5, and a shaft is attached to the inner peripheral part of the iron core part 3 and the reinforcement ring 6. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
