Abstract
Abstract A rotatable element (1) is arranged on a supporting member (2). The element (1) is freely rotatable and displaceable radially by being held in position by two portions (5,6) attracting each other, said portions being made of magnetic material, and that a plain slot (3) separates the supporting member and the element (1). The driving of the element (1) can be effected thereby that the element forms or incorporates a rotor in an electromotor, the stator of which is arranged in an area (7) of the supporting member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
A device with a bearing for supporting a rotatable element (1) upon a supporting member, incorporating a mainly plain surface, whereby the rotatable element has an opposite plain surface and is arranged freely displaceable radially in at least one direction upon the first mentioned surface, characterized thereby. that both said surfaces are arranged thus that a pressure medium can cause a space between them, whereby at least a portion of one of the surfaces defining the space is arranged thus that pressurized gas can be introduced into the space between the surfaces in order to separate these, and that each one of the supporting member and the rotatable element, has one portion (5.6) of magnetic material, which portions are arranged along the rotational axis of the rotatable element and are mutually interspaced and attract each other.
Claim 2
Independent Claim
136 words
A device with a bearing for supporting a rotatable element (1) upon a supporting member, incorporating a mainly plain surface, whereby the rotatable element has an opposite plain surface and is arranged freely displaceable radially in at least one direction upon the first mentioned surface, characterized thereby. that both said surfaces are arranged thus that a pressure medium can cause a space between them, whereby at least a portion of one of the surfaces defining the space is arranged thus that pressurized gas can be introduced into the space between the surfaces in order to separate these, and that each one of the supporting member and the rotatable element, has one portion (5.6) of magnetic material, which portions are arranged along the rotational axis of the rotatable element and are mutually interspaced and attract each other.
Claim 3
Dependent Claim
50 words
A device as claimed in claim 1, characterized thereby, that a stator in an electric driving motor is arranged in the supporting member in connection (7) to the mainly plain surface thereon and a rotor belonging to said motor being arranged upon or being constituted of the rotatable element (1).
Claim 4
Independent Claim
37 words
A device as claimed in anyone of the preceding claims, characterized thereby, that it incorporates means (8) for radial actuation of the rotatable element to take up an eccentric position against the action of the attracting forces.
Claim 5
Independent Claim
34 words
A device as claimed in anyone of the preceding claims, characterized b y, means for effecting a pressure in the medium contained in the slot (3) due to the rotation of the element (1).
