Abstract
A removable magnetic suspension system for a rotor comprising at least one electromagnetic bearing constituted by an armature supported by a sleeve fast with the rotor and a stator mounted on a fixed support, and at least one electromagnetic rotor-position detector constituted by a fixed stator cooperating with a part forming an armature integral with the rotor for controlling the bearing characterized in that the detector is mounted independently of the bearing which it controls and comprises a stator removably mounted on a fixed support and disposed directly opposite a reference surface formed on the rotor and independent of the sleeve supporting the bearing armature.
Claims9
A removable suspension system for a rotor that revolves with respect to a stationary assembly, comprising:
- (a) a sleeve removably engaged on said rotor and maintained selectively affixed thereto by gripper means;
- (b) at least one electromagnetic bearing including a bearing armature supported by said sleeve and a stator mounted on a fixed support in operative position with respect to said bearing armature;
- (c) at least one electromagnetic rotor-position detector mounted on said fixed support independently from said at least one electromagnetic bearing, for controlling said electromagnetic bearing, said electromagnetic rotor-position detector including:
- (i) a reference surface formed on said rotor, said reference surface constituting a detector armature for said at least one electromagnetic rotor-position detector;
- and
- (ii) a stator removably mounted on said fixed support disposed directly opposite said reference surface on said rotor and independent from said sleeve.
A removable suspension system for a rotor having a finished surface portion disposed near an end portion thereof;
- comprising:
- (a) a sleeve, said sleeve including gripper means for selectively maintaining the rotor affixed therein;
- (b) at least one electromagnetic bearing including a bearing armature supported by said sleeve and a stator mounted on a fixed support in operative position with respect to said bearing armature;
- (c) at least one electromagnetic rotor position detector mounted on said fixed support independently from said at least one electromagnetic bearing for controlling said electromagnetic bearing;
- and
- (d) said electromagnetic rotor position detector including a stator mounted on said fixed support, said stator being disposed directly opposite said finished surface portion on said rotor whenever said rotor is affixed in said sleeve, said finished surface portion thereby forming a reference surface constituting the detector armature.
