Abstract:
A dynamoelectric device comprising:a rotor having an axis of rotation;a plurality of stator poles positioned circumferentially about the rotor axis, the stator poles being circumferentially spaced apart defining slots extending axially between adjacent stator poles;a plurality of windings, each winding being at least one electrically conductive wire wound about at least one stator pole; andat least one retaining member, the at least one retaining member being positioned within one of the slots, the at least one retaining member having a main body operatively connected to both adjacent stator poles that form the slot, the main body being restrained by the adjacent stator poles from moving radially inward, the main body also being radially positioned between one or more of the windings and the rotor where the main body will prevent the one or more of the windings from contacting the rotor should the windings move radially inward, the retaining member also having at least one locking mechanism that engages a cooperating locking portion of the dynamoelectric device to limit axial translation of the retaining member relative to the stator poles, the locking mechanism including a first protrusion that is positioned on the main body to limit axial translation of the retaining member in a first direction and a second protrusion that is positioned on the main body to limit axial translation of the retaining member in an opposite, second direction, the first and second protrusions thereby limiting axial translation of the retaining member relative to the stator poles.
