Abstract: A gasket includes a rectangle formed from a sheet of material for placement over a pole of a stator, the rectangle including: a first side opposite a third side of equal length; a second side opposite a fourth side of equal length; pluralities of inner tabs disposed on the inner edges of the first and third sides, each inner tab being bent downward at a first angle to a plane containing the rectangle; outer tabs disposed on outer edges of the first and third sides and bent downward at a second angle; an inner tab disposed on the inner edge of the fourth side and angled upward from the plane containing the rectangle at a third angle; and two second protrusions disposed at opposite ends of an outer edge of the second side and two fourth protrusions at opposite ends of an outer edge of the fourth side.

Abstract: An assembly for an electric motor includes a stator including a plurality of stator poles, each stator pole including a base end and a rotor end opposite the base end, and an electromagnetic coil around each stator pole. The coil around each stator pole includes at least two electrically conductive wires wound into multiple wire turns around the stator pole that extend from the base end of the stator pole to the rotor end of the stator pole. Wire turns of the coil closer to the rotor end of the stator pole are twisted and wire turns of the coil closer to the base end of the stator pole are not twisted.
