Provided herein are systems, apparatuses, and methods of providing a centrifugally cast rotor assembly for an induction motor of an electric vehicle. The rotor assembly includes a rotor lamination stack with a cylindrical shape that terminates in a first end surface and a second end surface. The rotor lamination stack has multiple lamination discs, and each lamination disc has multiple rotor slots. The rotor assembly further includes copper bars disposed within the rotor slots, a first intermediary end ring disposed at the first end surface, and a second intermediary end ring disposed at the second end surface. A centrifugally cast first copper end ring that electrically and mechanically couples each of the copper bars is located proximate the first end surface, and a centrifugally cast second copper end ring that electrically and mechanically couples each of the copper bars is located proximate the second end surface.
