Direct current motor having low vibration electric brush system

The invention relates to a direct current motor having a low vibration electric brush system, comprising a rotor, a stator and an electric brush system; the electric brush system comprises a commutator segment, a carbon brush and a brush frame device; the brush frame device comprises a brush rod used for fixing the electrode wire and a brush handle; the brush rod is fixed on a brush rod seat; thecarbon brush is fixed in a locating cavity of the brush handle; a constant pressure spring is connected between the carbon brush and the brush handle in insulating manner; one end of the carbon brushis contacted with the surface of the commutator segment, and the other end thereof is connected with the constant pressure spring; and a damping gasket used for reducing the vibration is installed between the brush rod and the brush rod seat, and/or between the constant pressure spring and the carbon brush. The motor has the advantages of low noise and vibration, small volume, simple structure and convenient maintenance an
