直流モータ用磁気回路。An even number of pole pieces 2 radially combined, leaving a cylindrical space 3 for accommodating a rotor in the central axis portion, are connected from both ends in the central axis direction by permanent magnet pairs 4, 4 with the same poles facing each other. The magnetic circuit for a DC motor is characterized in that the permanent magnets 4 on the same end side are connected by a yoke 6 so that a magnetic path is formed on the side opposite to the pole piece.
