A method for manufacturing a polymeric electrical machine includes manufacturing a stator including a laminated stator core and a plurality of windings including winding overhangs; applying a surface treatment to the stator core constructed to reduce defects at an interface between a polymeric material and the stator core and enhance adherence between the polymeric material and the stator core; mounting the stator onto a mandrel; inserting the stator into an electrical machine housing mold; molding an electrical machine housing including a stator band with an integral non-drive end endplate, including overmolding the stator and winding overhangs within the stator band; molding a drive end endplate, including forming polymeric ribs in the drive end endplate and overmolding a metallic structure into the endplate, the metallic structure enhancing mechanical stiffness of the endplate; installing a rotor assembly into the electrical machine housing; and installing the endplate onto the electrical machine housing.

Manufacture of a polymeric electrical machine

An electrical machine comprises a polymeric housing having a stator band, the polymeric housing formed by a polymeric material and constructed to house components of the electrical machine, structurally support the electrical machine and react torque loads generated by the electrical machine; a stator overmolded into and partially encapsulated by the stator band, the stator including a laminated stator core and a plurality of stator windings; a rotor in magnetic communication with the stator; a first endplate integral with the polymeric housing; and a second endplate, the second endplate being a polymeric endplate, the second endplate including a plurality of ribs and a metallic structure, wherein the electrical machine is constructed as an industrial electrical machine.

Polymeric industrial electrical machine

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.

Apparatus and method for forming an article

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.

A method for injection molding of thermoplastic pole parts utilizes a mold to fix at least one vacuum interrupter and contact terminals during a molding process. At least one injection opening or gate for injection of thermoplastic material is formed into the mold. The mold is applied with multiple injection openings at least along its long axis, for injection of hot thermoplastic material, and the injection openings or gates can be steered in such a way that they inject thermoplastic material simultaneously or with a defined time dependent injection pattern. This process alleviates the issue of a pressure gradient along the long axis of the molded pole part, shortens process times, and achieves a homogenous dissipation of material during the molding process.
