===Stator===
{{main|Stator}}

The stator surrounds the rotor, and usually holds field magnets, which are either [[electromagnet]]s (wire windings around a ferromagnetic iron core) or [[permanent magnet]]s. These create a [[magnetic field]] that passes through the rotor armature, exerting force on the rotor windings. The stator core is made up of many thin metal sheets that are insulated from each other, called laminations. These laminations are made of [[electrical steel]], which has a specified magnetic permeability, hysteresis, and saturation. Laminations reduce losses that would result from induced circulating eddy currents that would flow if a solid core were used. Mains powered AC motors typically immobilize the wires within the windings by impregnating them with varnish in a vacuum. This prevents the wires in the winding from vibrating against each other which would abrade the wire insulation and cause premature failures. Resin-packed motors, used in deep well submersible pumps, washing machines, and air conditioners, [[Potting (electronics)|encapsulate]] the stator in plastic [[resin]] to prevent corrosion and/or reduce conducted noise.<ref>{{Cite web|title=Resin-Packed Motors|url=https://www.nidec.com/en/technology/casestudy/resin_pack_motor/|website=Nidec Corporation}}</ref>
