Patent ID: 8373320

Claim:
A stator comprising: a stator core; an insulator fitted on an axial end face of the stator core; and coils wound around the stator core and the insulator, the insulator having an annular portion, a plurality of circumferentially arranged tooth portions projecting radially inwardly from an inner peripheral surface of the annular portion, and a cylindrical-shaped wall section erected on an axial end face of the annular portion such that the wall section axially extends, and the coils including crossover wires routed on an outer peripheral surface of the wall section of the insulator so as to extend obliquely relative to a plane orthogonal to an axis of the stator, as viewed in a direction orthogonal to the axis, and the wall section of the insulator having at least first, second and third stages in different axial positions of the wall section, the at least first, second and third stages extending in a circumferential direction of the wall section, and at least one of the crossover wires including at least first and second pull-out portions pulled out from an inner surface to an outer surface of the wall section, and at least first and second pull-in portions pulled in from the outer surface to the inner surface of the wall section, the first and second pull-out portions corresponding to the first and second pull-in portions, respectively, with the first pull-out portion positioned in the first stage the first pull-in portion and the second pull-out portion positioned in the second stage next to the first stage, and the second pull-in portion positioned in the third stage next to the second stage.
