Abstract
A stator for a motor includes a stator core of a hollow columnar structure. The stator core includes a first end and a second end in an axial direction. The stator core defines a first oil cooling channel and a second oil cooling channel through in the axial direction. The first oil cooling channel has a first oil inlet at the first end and a first oil outlet at the second end. The second oil cooling channel has a second oil outlet at the first end and a second oil inlet at the second end. At the first end, the first oil inlet and the second oil outlet are arranged along a circumferential direction of the stator core and located on a same circumference centered around an axis of the stator core.
