Patent ID: 8303185

Claim:
A rotating machine, comprising a constant speed rotating machine, comprising: a rotor; a stator; a radial bearing arranged for supporting radial forces between said rotor and said stator by mechanical contacts; a bearing housing attached to said stator and being in direct mechanical contact with said radial bearing, said bearing housing including at least one cavity therein; a conduit passing through said stator into said bearing housing for supplying a fluid to said stator into said bearing housing to either raise or lower the temperature of said bearing housing; thermal control means comprising a heater or cooler for controlling the temperature of said fluid during operation of said rotating machine; a senor arranged for measuring properties of a least one of said stator and said rotor; and said senor being connected to said thermal control means for providing signals associated with said measured properties; whereby said thermal control means can control said temperature of said bearing housing by said supply of said fluid in response to said measured properties in order to reduce vibrations in said rotating machine.
