Claims

[Scope of utility model registration request]

In a rotating electric machine that uses a frame as an axial magnetic path for DC magnetic flux, the ring consists of an iron core having a plurality of grooves on the outer periphery of the ring, and a field coil inserted into the grooves, the outer diameter of which is inserted tightly into the frame, A field core for a rotating electric machine configured such that the inner diameter side faces the rotor side magnetic path through an air gap.
