Claims

[Scope of utility model registration request]

a stator core which is an annular body and has a plurality of winding grooves extending in the axial direction at a predetermined interval of 4 in the circumferential direction near the inner surface of the annular body; A stator winding housed through insulation, and a non-magnetic stator winding fixedly held in the winding groove and held by fitting into core teeth formed between adjacent winding grooves. a wedge, a rotor core rotatably disposed in the annular hollow part □ of the stator core and formed shorter in the axial direction than the stator core; and a rotor core wound around the rotor core; a rotor winding having an end protruding from the iron core in the axial direction; the end of the winding being firmly held;
and a rotating electrical machine comprising a winding holding ring made of a conductive material that rotates integrally with the rotor core, and a rotating shaft that holds the rotor core, the rotating electric machine facing the winding holding ring. A synchronous rotating electric machine characterized in that a magnetic transmission device for magnetically connecting adjacent teeth is provided only in the vicinity of the region where the stator windings are located and near the tips of the iron core teeth formed between the adjacent stator winding grooves.
