Abstract
A mold for forming a plurality of rotors includes a plurality of lamination stacks, wherein each lamination stack defines at least one void therethrough; a tube having a central longitudinal axis, wherein each lamination stack is concentrically spaced apart from the tube to define a channel therebetween; a plurality of washers each having a shape defined by a first diameter and a second diameter that is greater than the first diameter, wherein each washer is configured to concentrically abut the tube and define a feed conduit interconnecting with the channel; and a shell disposed in contact with each lamination stack and concentrically spaced apart from each washer to define a plurality of ducts, wherein each duct is interconnected with the at least one void of at least one lamination stack. A mold system and a method of forming a plurality of rotors are also described.
