A direct current motor including a rotor, a stator, a brush holder, and a brush. The rotor includes a core, a plurality of commutator segments, and a plurality of segment coils. The core has a plurality of teeth arranged along a circumferential direction of the rotor. A slot is formed between adjacent ones of the teeth in the circumferential direction. The plurality of commutator segments are arranged along the circumferential direction of the rotor inward from the plurality of teeth in the radial direction of the rotor. Each segment coil includes a plurality of segment conductors electrically connected to each other. The plurality of segment conductors in each segment coil extends through the slots along the axial direction of the rotor.
