Abstract
A method of forming a rotor includes inserting a conductor bar into a slot defined by a lamination stack to define a gap between the conductor bar and the lamination stack. The method further includes, after inserting, swelling the conductor bar within the slot to fill the gap and form the rotor. A rotor is also disclosed.
