A rotating machine is disclosed including a rotor, a stator, a radial bearing arranged for supporting radial forces between the rotor and the stator by mechanical contacts and a bearing housing. The bearing housing is provided in the stator or the rotor in direct mechanical contact with the radial bearing and the rotating machine further comprises a thermal energy exchanger, arranged in the bearing housing, and a thermal controller. The thermal energy exchanger is capable of providing both heat and cold, and the thermal controller is arranged to control the thermal energy exchange during operation of the rotating machine. The rotating machine is typically a large machine, such as a refiner. A method for vibration control of a rotating machine is also disclosed comprising measuring properties related to vibrational properties. |
