[Scope of utility model registration request] It consists of an armature core around which an armature winding is wound, and a field core around which a field winding is wound around a plurality of magnetic poles facing the armature core at intervals along the circumferential direction. In a salient pole type rotating electrical machine, a first magnetic shielding body having an L-shape, one side of which is provided in the axial direction between the magnetic poles, and the other side of which covers one end of the adjacent magnetic poles in the axial direction; a second magnetic shield whose one side is provided in the axial direction between the next magnetic pole and whose other side covers the other end of the adjacent magnetic pole in the axial direction; are attached alternately to the magnetic poles in the circumferential direction, and the first and second magnetic shields are made of a superconducting material and are maintained at a temperature below a critical temperature at which a superconducting state is achieved. Rotating electric machine.
