Abstract
A rotary electric machine stator includes a stator core including a plurality of teeth, a coil wound around the teeth, a power wire being drawn out from the coil, and a retainer member that presses the coil end against the stator core. The retainer member includes a pressing portion disposed on an end surface in an axis direction of the coil end, leg portions extending from respective end portions on opposite sides of the pressing portion toward respective attachment portions provided at the stator core, and attachment ends provided at the respective leg portions and fixed to the respective attachment portions, and the power wire is drawn out from between the leg portions on the opposite sides of the pressing portion.
Claims11
A rotary electric machine stator comprising:
- a stator core including an annular stator yoke and a plurality of teeth protruding inward from the stator yoke;
- a coil wound around the teeth, a power wire being drawn out from the coil;
- and
- a retainer member configured to press a coil end against the stator core, the coil end being a part of the coil, the coil end protruding from an end portion in an axis direction of the stator core, the retainer member including a pressing portion, leg portions and attachment ends, the power wire being drawn out from between the leg portions on opposite sides of the pressing portion, the pressing portion being disposed on an end surface in the axis direction of the coil end and configured to press the coil end to the stator core side, the leg portions bending along the axis direction on an outer peripheral surface side of the coil end from respective end portions on the opposite sides of the pressing portion and extending toward respective attachment portions provided at the stator core, and the attachment ends being provided at the respective leg portions and fixed to the respective attachment portions of the stator core, wherein
- the pressing portion of the retainer member is a flat plate-shaped member that is straight, and respective ones of the leg portions of the retainer member directly extend from each longitudinal end of the flat plate-shaped member.
