Methods and apparatus for an electric machine with a cast rotor
A squirrel cage rotor structure used in connection with an electrical machine is formed from a high-strength, high-conductivity, and heat-treatable aluminum alloy, e.g., a T61 tempered aluminum alloy, such as A6101-T61. The resulting structure has improved strength compared to conventional pure aluminum structures, while at the same time limiting the reduction in electrical conductivity.
