As described above, according to this invention, in the stator of a magnetic rotating electrical machine in which a composite type field magnetic pole made of a permanent magnet material is fixed to the inner peripheral surface of a cylindrical yoke, the field magnetic pole is It consists of a main magnetic pole of the mold and auxiliary magnetic poles of different properties fixed to the inner peripheral surface of both ends of the main magnetic pole, the main magnetic pole is made of barium ferrite permanent magnet material, and one of the auxiliary magnetic poles is made of a high coercive force.・Since one of the magnets is made of a rare earth-containing magnet material exhibiting a high magnetic flux density, and the other is made of a soft ferrite magnet material, the reaction magnetic flux caused by the rotor is canceled by the auxiliary magnetic pole made of the rare-earth magnet material. The auxiliary magnetic pole made of soft ferrite magnet material suppresses the excitation magnetic flux caused by the magnet, so that good magnetic properties can be obtained, and moreover, the amount of high-grade magnet used can be reduced.
