Claim 16:
17. A method of manufacturing an electric motor, the method comprising:
forming a plurality of layers in a sheet of material, wherein each layer of the plurality of layers has an inner profile and an outer profile and comprises a sheet of material having a nominal thickness;
assembling the plurality of layers to form a stator lamination assembly, wherein the inner profiles corresponding to the plurality of layers, when assembled into the stator lamination assembly, form slots dispersed around a hole configured to accept a rotor, and the outer profiles corresponding to the plurality of layers, when assembled into the stator lamination assembly, include a number of features on an exterior surface of the stator lamination assembly that enable the electric motor to be configured in accordance with a plurality of enclosure types, wherein the number of features on the exterior surface of the lamination includes a retaining feature configured to accept a cover;
placing coils of insulated conductors in the slots of the stator lamination assembly;
assembling the stator lamination assembly with one or more end plates and a rotor disposed in the hole of the stator lamination assembly to form the electric motor; and
configuring the electric motor to conform to one of the plurality of motor enclosure types.
