Cooling structure for oil-cooled electric machine
A cooling structure for an oil-cooled motor includes a motor housing, within which a stator core is provided. The stator core includes a middle stator lamination and end stator laminations at both ends. The outer circumference of both the middle and end stator laminations is provided with multiple bending grooves. The arc edge between any two adjacent bending grooves corresponds to a central angle, one of which has a different degree than the others, while the remaining central angles have the same degree. The bending grooves of the middle stator lamination are aligned and superimposed, forming multiple first cooling oil channels on the outer circumference of the stator. The bending grooves of the end stator laminations at both ends are misaligned with the bending grooves of the middle stator lamination, causing the first cooling oil channels of the middle stator lamination to be partially blocked, forming multiple spray holes. One of the first cooling oil channels located at the bottom of the stator is completely blocked by the end stator lamination, thus not forming a spray hole.
