Abstract

A stator, a motor, and an electric vehicle are provided. The stator includes: a housing, where the housing has an accommodation space, and an oil inlet is disposed on the housing; a ring-shaped iron core punching sheet, where the iron core punching sheet is disposed in the accommodation space, and abuts against an inner wall of the housing; a spacer sleeve, where the spacer sleeve is sleeved in the iron core punching sheet, an outer surface of the spacer sleeve abuts against a side that is of the tooth part and that faces away from the yoke part, and a slot opening of the stator slot fits with the spacer sleeve to form a third cooling channel; and a flow guiding assembly, where the flow guiding assembly is disposed in the accommodation space. The three-layer oil-injection cooling design can improve a heat dissipation capability of the stator.
