Claims

[Scope of utility model registration request]

An even number of main magnetic poles are arranged on the outer periphery of an inner cylinder of a double cylinder made of a magnetic material, and a hollow cylindrical shape is formed in the radial gap between the main magnetic poles and the outer cylinder to support the winding. In a DC rotating electric machine having a rotor winding body without an iron core, which is fixed to a rotating shaft by a body, the inner cylinder is constructed by laminating a plurality of magnetic plates, and the main magnetic pole is fixed on both sides of the outer periphery. axial protrusions having engaging protrusions are provided at equal intervals in the circumferential direction, and axial engagement grooves are provided on both sides of the main magnetic pole to engage with the engaging parts of the protrusions, A DC rotating electric machine characterized in that a main magnetic pole is engaged and fixed between each of the protrusions □ of the inner cylinder.
