A New Manufacturing Technology for Induction Machine Copper Rotors
نویسنده
چکیده
The benefits of energy and operational cost savings from using copper rotors are well recognized. The main barrier to die casting copper rotors is short mold life. This paper introduces a new approach for manufacturing copperbar rotors. Either copper, aluminum, or their alloys can be used for the end rings. Both solid-core and laminated-core rotors were built. High quality joints of aluminum to copper were produced and evaluated. This technology can also be used for manufacturing aluminum bar rotors with aluminum end rings. Further development is needed to study the life time reliability of the joint, to optimize manufacturing fixtures, and to conduct large-rotor tests.

Computer Aided Design for Single-Phase Induction Motors Based on a New Gemoetrical Approach
Design of electrical motors normally involves two main stages: i) Preparation of the main dimensions and parameters. ii) Prediction of the performance. At the first stage the main dimensions of the motor, core stack Lfe and stator outer diameter Do, must be chosen. A set of performance conditions such as breakdown torque, desired output and other important parameters must satisfy the internatio...
