The invention discloses a stator core of an electric vehicle stator permanent magnet motor, belonging to the automobile motor field, which is stamped from a strip-shaped silicon steel plate, and can be divided into a permeable yoke with thick permeable yoke and a connecting yoke with thin permeable yoke according to the thickness of the permeable yoke. The permanent magnet is embedded in the permeable yoke. The number of conductive yokes and connecting yokes is even and the outer yokes are arc-shaped, and the radius of curvature is equal to half of the inner diameter of the motor housing. Whenstamping, the permeable yoke and the connecting yoke are nested face to face. Compared with the stator core structure and the manufacturing process of the stator permanent magnet motor, the magneticcircuits between the opposite poles of the stator permanent magnet motor are mutually isolated, and the possibility of fault propagation caused by the fault is reduced. At the same time, two stator cores nested face-to-face are stamped, so that the manufacturing efficiency is high; Stamping with strip-shaped silicon steel sheets uses less scrap.
