High-power direct-current motor with integral end cover

A high-power direct-current motor with an integral end cover comprises a motor base, an end cover, an armature bearing, an armature, a stator, a brush holder, a commutator, a first wind deflector and a second wind deflector. The high-power direct-current motor is simple in structure and convenient to manufacture. The heat dissipation ability of the motor is improved, and air inlet and outlet from the bearing side of the motor is avoided. Moreover, carbon powder of the commutator is prevented from being blown into the bearing, and the service life of the bearing is improved.
