As in figure 2 it is shown, electric machine casing 400 includes the first housing 410 and the second housing 420, at the first housing 410 and second
The joint of housing 420, forms hierarchic structure 500 between medial surface and the medial surface of the second housing 420 of the first housing 410；
When motor stator 300 is arranged in electric machine casing 400, motor stator 300 abuts with hierarchic structure 500.So make these rank
Ladder structure 500 can the limiting motor stator 300 degree of freedom on axially and radially direction, such that it is able to avoid Oil pump electrical machinery to exist
Play in rotary course, improves the operational reliability of oil pump.
In one embodiment, for ease of processing and the installation of electric machine casing 400, the first housing 410 and the second housing 420
Use integrated design.Further, the lateral surface of the first housing 410 and the lateral surface of the second housing 420 are in same
In plane so that the lateral surface of electric machine casing 400 is streamlined, it is simple to the production of electric machine casing 400 and processing.First housing
The thickness of 410 is less than the thickness of the second housing 420 so that the medial surface of the first housing 410 and the medial surface of the second housing 420 it
