METHOD FOR CRYOSTATTING OF SUPERCONDUCTING WINDINGS OF A BRUSHLESS DC MOTOR Russian patent published in 2020 - IPC H02K55/02 H02K1/12 H02K9/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment. Cryostatting method of superconducting windings of stator of brushless direct-current motor, characterized by that it includes following stages: stage A is manufacturing of cryostat, inner tight space of which is formed by inner and outer walls of two coaxially located cylinders of larger and smaller diameters from electrically insulating material, installed on ends of covers with nozzles for supply of cryogenic medium and removal of superconducting wires and through openings formed by slots in cylinders and insulating inserts from electrically insulating material, where around the above inserts there are windings from high-temperature superconducting wires; stage B - heat insulation of cryostat by creation of layer with low heat conductivity around cryostat; stage C - cryostat filling with cryogenic medium.

EFFECT: technical result consists in simplification of design and reduction of weight and size characteristics.
