Abstract
A rotor for an electrical inductor motor or an induction generator includes a core having spaces formed in the core. The rotor also has a first end ring. The first end ring has a first hub portion. A first ring is connected to the first hub portion by first spokes. The rotor also has a second end ring. The second end ring has a second hub portion. A second ring is connected to the second hub portion by second spokes. The first end ring is secured to the core. The second end ring is rotated a predetermined amount so the first spokes are misaligned with the second spokes. The second end ring is connected to the first end ring and the core. The core, the first end ring and the second end ring form a substrate. An aluminum conductor is cast to the substrate. The aluminum conductor fills in the spaces and around the first and second spokes to form a cast rotor.
