SUPERCONDUCTING SYNCHRONOUS ELECTRICAL MACHINE Russian patent published in 2005 - IPC

FIELD: electrical engineering, applicable in power plants and electric drive systems.

SUBSTANCE: the machine has a stator positioned on which is a distributed armature winding with end components fastened on the carrying insulation cylinder, outer cylindrical ferromagnetic screen protecting the outer space against the machine magnetic field, side magneto impermeable disk-shaped screens, outer body and the rotor that is installed on shaft fastened in bearings, and consists of monopolar relative to the armature winding magnetic poles on the basis of superconductors separated from the armature by a running clearance, one from another - by non-magnetic interpolar gaps, and from the side screens - by axial gaps. The poles are fastened on a bush and enveloped by a cylinder fulfilling the functional of strong bandage and a damper winding, positioned in a cryostat and have a width equal to the width of the interpolar gaps, the values of magnetic induction above the poles and in the outer part of the interpolar gaps will be equal in module, but opposite in the direction, i.e. the magnetic field is a bipolar one.

EFFECT: enhanced electromagnet moment and current frequency in the armature winding due to the increase of the number of poles.
