SUPERCONDUCTING SYNCHRONOUS ELECTRIC MACHINE WITH THE ARMATURE WINDINGS AND EXCITATION IN THE FIXED CRYOSTAT Russian patent published in 2018 - IPC H02K55/02 H02K3/02 H02K1/27 

FIELD: electrical engineering.

SUBSTANCE: invention relates to power industry. Superconducting synchronous electric machine the with armature windings and excitation in a stationary cryostat comprises the magnetically conductive shields 1 and 2, the magnetically conductive body 3, stator 4, performed laminated, on the teeth of which the multiphase multi-pole armature winding 5 is made, made of the high-temperature superconductor tape of the 2^nd generation (HTSC-2) in the form of race track coils. Machine also contains the claw-like rotor that is mounted on the shaft, which presents the claw-like pole systems 6 and 7 with radially 8 and tangentially 9 magnetized permanent magnets. In the pole gap between the edge of the pole of one polarity and the pole system of the other polarity, the end permanent magnets 10 are arranged. On the stator, the annular superconducting excitation windings (ASEW) 11 and 12, made of HTSC-2 tape, are installed. Superconducting excitation windings and the armature winding are located in the common fixed cryostat 13 on the stator.

EFFECT: increase in specific power, efficiency, reliability, ensuring compactness.
