PURPOSE:To reduce the torque ripple and to obtain a strong rotary torque of a DC motor by forming a commutator with 10segments, field poles in 4-poles and groove angle width of a conductor which contributes to the torque generated at an armature winding substantially equal to the poles of the field. CONSTITUTION:A field pole 9' has 4 poles. An armature winding 4' which is wound on the side of a rotor 1' body is formed in width substantially equal to the pole width of the pole 9' in the groove angle of the conductor unit which contributes to the generated torque. A rotational shaft is fixed to the center or a rotor 1', and a commutator 6' is fixed onto the same shaft as the rotational shaft. This commutator 6' is formed of 10segments 6'-1-6'-10. |
