Abstract
A stator core suspension system includes a spring bar(s) coupled to a stator core and a frame for vibrationally isolating the stator core from the frame. A longitudinal axis of the spring bar is positioned in a plane extending substantially perpendicular to an axis of the stator core. The stator core suspension system can be arranged in modular suspension sections for selective assembly into a related dynamoelectric machine.
Claims20
A stator core suspension system comprising:
- a section member positioned about the stator core, the section member including a first spring bar support and an adjacent, second spring bar support;
- a spring bar having a first end coupled to the first spring bar support and a second end coupled to the adjacent, second spring bar support such that the spring bar extends in a plane substantially perpendicular to an axis of a stator core;
- a keybar coupled to the stator core;
- and
- a spring-to-keybar member coupling the spring bar intermediate the first and second ends to the keybar.
A stator core suspension system comprising:
- a plurality of modular suspension sections adapted to be coupled together, each modular suspension section including:
- a section member including a plurality of circumferentially spaced spring bar supports;
- a plurality of spring bars, each spring bar having a first end coupled to a first spring bar support and a second end coupled to an adjacent, second spring bar support such that the plurality of spring bars are longitudinally positioned in a plane;
- and
- a keybar coupled to each spring bar intermediate the first and second ends, each keybar configured for coupling to a stator core.
A dynamoelectric machine comprising:
- a rotor;
- a stator core about the rotor;
- and
- a stator core suspension system including a plurality of modular suspension sections adapted to be coupled together, each modular suspension section including:
- a plurality of spring bar supports positioned by a section member in a circumferentially spaced arrangement about the stator core;
- a plurality of spring bars, each spring bar having a first end coupled to a first spring support and a second end coupled to an adjacent, second spring bar support such that the plurality of spring bars are longitudinally positioned in a plane;
- and
- a keybar coupled to each spring bar intermediate the first and second ends, each keybar configured for coupling to a stator core section of a stator core.
