More Information
Summary:A method is provided that utilizes pre-fabricated conductive rotor bars and die cast end rings to fabricate a structurally robust rotor assembly capable of maintaining mechanical balance and electrical performance over wide temperature, torque, and rotational speed ranges. Containment rings, which may be installed on the end rings either before or after casting, may be used to inhibit end ring creep at high rotational speeds.
