Abstract
A motor has a field body having a number of field poles and an armature body having a number of coils which is placed outside of the above described field body in the radial direction. A commutator secured to the armature body has a number of segments to which the coils are respectively connected. The motor has a power supplying part for supplying a current to the coils and a brush holder which is secured to the field body. The brush holder contains an anode side brush device which makes contact with and slides against the commutator and the power supplying part and a cathode side brush device which makes contact with and slides against the commutator and the power supplying part. Accordingly, the efficiency of use of the coils can be increased.
