Three or more coil parts wound around the core axis, and stator facing parts provided in each coil part and having a number corresponding to the number of poles in one coil part on the same pole side. The stator facing part of each coil part has a pitch angle determined by "360 degrees/(number of poles x number of coil parts)" and is arranged sequentially. multiplied by the number of poles, and the lead wires from each of the coil parts are connected so as to be sequentially energized to the coil part having a stator facing part located between adjacent N and S poles of the stator. The width in the rotating direction is set to be smaller than the segment width so as not to contact three segments at the same time, and the rectifying part is provided with segments that are connected to the rectifying part. 1. A DC rotating electric machine, characterized in that the coil bobbin constituting the coil part has a locking part for locking a lead wire formed on an outer peripheral edge of the coil bobbin that is in contact with the brush.
