Abstract: A method for forming an article of manufacture using additive manufacturing, includes: a processor executing program instructions to: (a) rotate an object continuously about a horizontal axis using a first rotational stage, wherein the object is partially submerged in a bath of energy curable liquid formulation during the rotation; (b) control a rate of rotation of the object to achieve a desired radial thickness of a sub layer of uncured liquid formulation at a desired rotational location on the object; (c) direct an energy source to provide an energy dose onto the object at a desired rotational location, wherein the energy dose is configured to cure and solidify the sub layer; and repeat (a), (b) and (c) until a desired radial thickness of a cured liquid formulation layer is a achieved.

Abstract: An electrical machine has a nonmetallic housing having a stator band and an endplate, wherein the laminated stator core is in self-locked engagement with the housing. Another electrical machine has a unitary nonmetallic housing with an integral stator band and an integral endplate, wherein the laminated stator core is over-molded with the housing. Yet another electrical machine has a unitary nonmetallic housing with an integral stator band and an integral endplate, wherein the laminated stator core is in engagement with the stator band with an interference fit.
