PROBLEM TO BE SOLVED: To provide a permanent magnet commutator motor comprising a stator having a stator yoke structure capable of altering the profile of a stator yoke easily, and facilitating assembly of the stator yoke and a permanent field magnet. SOLUTION: The stator yoke 11 is formed of a sintered compact of a ferromagnetic material, protrusions 31e and 31f for latching field magnets 12a and 12b are provided on the inner circumferential surface of the stator yoke 11, and the field magnets 12a and 12b are clamped by the latching protrusions 31e and 31f and a spring member 41f thus bonding the field magnets 12a and 12b easily to the inner circumferential surface of the stator yoke 11.
