An analytical calculation of inductive parameters of toroidal high temperature superconducting armature winding of synchronous electrical machine

Zechikhin B., Kovalev K., Penkin V., Zadachin A.

This work presents the results of analytical investigation on calculation of inductive parameters of toroidal armature winding which is produced from high temperature superconducting tape of the first generation or the second one to be used in fully superconducting synchronous electrical machine. The optimal scheme of screening for outer part of the winding is obtained both from the point of view to decrease inductance of winding and electrical losses in screening shells.

Keywords: fully superconducting synchronous electrical machine, high temperature superconducting tape, armature, toroidal winding, inductance, electrical losses, screening shell.
