ABSTRACT:
A rotor for an induction motor. The rotor includes a core, a pair of end rings, and a plurality of aluminum conducting members. The core includes a plurality of accommodating holes that are aligned circumferentially in a peripheral portion of the core. The accommodating holes extend from one end surface of the core to the other. The end rings are formed of aluminum alloy. Each of the end rings has a plurality of support holes corresponding to the accommodating holes. The support holes are aligned circumferentially in a peripheral portion of each end ring. The end rings are each disposed at a corresponding one of the opposing ends of the core such that the support holes are opposed to the accommodating holes. Each of the conducting members is received in a corresponding one of the accommodating holes and the associated support holes. Each conducting member is supported by each of the end rings at a support portion located in the corresponding support hole.
