PROBLEM TO BE SOLVED: To provide a DC motor which can suppress the diametrical vibration at rotation of a motor. SOLUTION: A DC motor 101 is equipped with a stator 102 which has magnets 105 of six poles which change alternately in its circumferential direction, an armature 3 which has a commutator including 24 pieces of segments, an armature core 107 which is equipped with eight pieces of teeth T1-T8, and armature coils M1-M8 which are wired to specified segments and are wound two or more times concentratedly on the teeth T1-T8 of the armature core 107, and where all of the armature coils M1-M8 are connected in series to constitute one closed loop thus wiring the armature coils M1-M8, and brushes on anode side and cathode side which slide on the segments so as to perform power supply. In the stator 102, the magnet 105 is made cylindrical. COPYRIGHT: (C)2007,JPO&INPIT
