A direct current motor having E-shaped interpoles, each of the E-shaped interpoles comprising interconnecting members which are made of a non-magnetic material having rigidity and which are tightly and irremovably inserted in gaps between a center pole and side poles of the E-shaped interpole. In the direct current motor according to the present invention, the side poles are mechanically interconnected to the center pole, so that noises generated by the vibration of the side poles are greatly reduced.
