THRUST ELECTROMAGNET BEARING Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: according to the first variant, the thrust electromagnetic bearing has ring electromagnets and disk set on the rotor shaft provided with a safety bearing, and axial position pickup. The pickup is made of working and compensating toroidal coils secured to the inserts made of an insulating material. The answering part of the working coil is made of a disk made of a conducting material and set on the shaft face. The working and compensating coils of the pickup are arranged in the common casing which is mounted for permitting simultaneous axial movement of the coils with respect to the face of the shaft. According to the second variant, the thrust electromagnetic bearing has ring electromagnets and disk set on the shaft of the rotor provided with axial safety bearing and axial position pickup. The shaft is provided with a step, and pickup is made of working and compensating toroidal coils secured to the insulating inserts which embrace the shaft. The answering part of the working coil is made of a ring made of a conducting material.

EFFECT: improved design.
