发明名称 Stator for rotating electric machine
摘要 A stator includes an annular stator core, a stator coil and at least one protective wall. The stator core has a plurality of slots formed therein. The slots are spaced from one another in a circumferential direction of the stator core. The stator coil is comprised of a plurality of windings mounted on the stator core. The windings are connected in a predetermined manner to form a plurality of connection portions therebetween. The connection portions are located outside the slots of the stator core on one axial side of the stator core. The at least one protective wall is provided radially inside the connection portions of the stator coil so as to shield the connection portions from the radially inside of the stator.

主权项 1. A stator for a rotating electric machine, the stator comprising: an annular stator core having a plurality of slots formed therein, the slots being spaced from one another in a circumferential direction of the stator core; a stator coil comprised of a plurality of windings mounted on the stator core, the windings being connected in a predetermined manner to form a plurality of connection portions therebetween, the connection portions being located outside the slots of the stator core on one axial side of the stator core, wherein at each of the connection portions, two or more of the windings are electrically connected with each other to form a junction point between the two or more of the windings; and at least one protective wall provided radially inside the connection portions of the stator coil so as to shield the connection portions from a radially inside of the stator, the at least one protective wall extending over an entire circumferential range of the connection portions, wherein the stator coil has a coil end part that protrudes from an axial end face of the stator core, the connection portions protruding from the coil end part; andthe at least one protective wall is provided axially outside the coil end part.
