Abstract
An induction rotor assembly having conductive bars is provided. The assembly comprises a lamination stack comprising a body having a first end and second ends to define a longitudinal axis. The body has an outer circumferential portion extending from the first end to the second end. The outer portion has a plurality of walls defining open slots formed from the first end through the second end. The assembly further comprises a first ring disposed on the first end and a second ring disposed on the second end. The assembly further comprises a plurality of conductive bars extending between the first and second rings.
