The torque rippless DC motor comprises a shaft (11) supported to a housing (12) by a bearing (13), a boss (14) fixed at the upper of the shaft, a rotary rotor (15) where a donut type permanent magnet (16) is attached, an inner fixed plate (18) of an armature core (17) fixed to the housing, an yoke (20) fixed to an outer fixed plate (19) of the armature core, and an winding coil winded at the amateur core in the same direction. Torque is produced in proportion to the amount of voltage in the winding coil.
