Abstract
A wave spring is provided for securing a stator in a dynamoelectric machine. The wave spring is disposed on one end of the stator between a support chassis for the stator and the stator, and compressed thereon to secure the stator in a fixed position in the support chassis. The compressed wave spring provides sufficient force to prevent movement of the stator during operation in various environments. In a further aspect of the invention, the opposing surfaces between which the wave spring is compressed include recesses which receive portions of the wave spring. The recesses are offset, and are effective in further inhibiting rotation of the rotor inside the support chassis for the stator, and may also be used for positioning the stator therein.
Claims20
A device for securing a stator in a dynamoelectric machine, wherein said dynamoelectric machine includes a support chassis for the stator in spaced relationship to an axis of rotor rotation and said stator positioned in said support chassis in spaced relationship around said axis, said device comprising:
- at least one wave spring disposed on at least one end of said stator between said support chassis for the stator and said stator;
- and
- means for compressing said wave spring between said support chassis for the stator and said stator;
