Abstract
A stator includes a stator core and a stator winding. The stator core includes a plurality of stator teeth and a core oil passage extending in an axial direction. The stator winding is wound on the stator teeth, and a projection of the stator winding and a projection of the core oil passage in the axial direction of the stator are overlapped. The core oil passage includes a spiral first oil passage section, the stator core includes first and second laminations stacked with each other, the first and second laminations have first and second oil holes both passing through the respective laminations along the axial direction, respectively, the first and second oil holes are staggered in a peripheral direction and in partial communication with each other, and at least one first lamination is adjacent to at least one second lamination to define the first oil passage section.
