Abstract
A resolver stator that is mounted on a target structure including a knock pin, the target structure having a hole, a portion of the knock pin being disposed in the hole, the resolver stator including: a stator core that has an engaging groove configured to be engaged with the knock pin, and the stator core includes a yoke; and a resolver cover covering the yoke in a central axis direction of the resolver cover, the resolver cover being made from metal and having a first cutout, the first cutout being disposed such that the first cutout overlaps at least a part of an end surface of the knock pin engaged with the engaging groove, at the center axial direction.
Claims8
A resolver stator that is mounted on a target structure including a knock pin, the target structure having a hole, a portion of the knock pin being disposed in the hole,
- the resolver stator comprising:
- a stator core that has an engaging groove configured to be engaged with the knock pin, and the stator core includes a yoke;
- and
- a resolver cover covering the yoke in a central axis direction of the resolver cover, the resolver cover being made from metal and having a first cutout, the first cutout being disposed such that the first cutout overlaps at least a part of an end surface of the knock pin engaged with the engaging groove, in the central axis direction,
- wherein the first cutout extends radially inward from an outer peripheral edge of the resolver cover towards a central axis of the resolver cover.
A resolver stator that is mounted on a target structure including a knock pin, the target structure having a hole, a portion of the knock pin being disposed in the hole,
- the resolver stator comprising:
- a stator core having an engaging groove configured to be engaged with the knock pin;
- and
- a metallic fixing plate that is screwed and joined to a bolt configured to pass through the target structure and the stator core from a back surface of the target structure, the fixing plate being configured to sandwich and fix the stator core together with the target structure,
- wherein the fixing plate has a second cutout, and the second cutout is disposed such that the second cutout overlaps at least a part of an end surface of the knock pin engaged with the engaging groove, in a central axis direction of the fixing plate;
- and
- the second cutout extends radially inward from an outer peripheral edge of the fixing plate towards a central axis of the fixing plate.
