A discharge assembly (46) is mounted to the first port and comprises a discharge valve (48) and a charge conduit (50) at least partially within the interior. The discharge conduit has an interior and an exterior. A liquid level measurement assembly (82; 200; 250; 300; 400) is mounted to the second port and comprises: a tube (100) at least partially within the tank interior and having an interior sealed relative to the surrounding tank interior and an exterior; a float (120; 220) surrounding the tube; and a member (122; 222; 252; 302) axially movable within the tube interior. One of the float and the member comprises an upper magnet (130; 230) and a lower magnet (132; 232). The other of the float and the member magnetically cooperates with the upper magnet and the lower magnet to relatively axially trap the member to the float.

Abstract: A stator for an electric motor having a rotation axis includes a plurality of electric coils. Each one of the plurality of electric coils include an inner winding layer, a plurality of mid-winding layers, and an outer winding layer. The inner winding layer is wound about and spaced from a centerline that generally intersects the rotation axis, and defines an opening for the flow of cooling air. The plurality of mid-winding layers are disposed radially outward from the inner winding layer with respect to the centerline. Each mid-winding layer of the plurality of mid winding layers is disposed radially inward from the next adjacent mid-winding layer with respect to the centerline. The outer winding layer is disposed radially outward from the plurality of mid-winding layers with respect to the centerline.
