The invention discloses an efficient radiating dust-proof motor, and the structure thereof comprises a radiator, a main frame of the motor, a rotating shaft, a front cover, a through hole, a motor fixing seat, a hexagon socket screw, a junction box, a back cover, a commutator and a clamping block, wherein the left end of the main frame of the motor is fixedly connected with the right end of the front cover by screws, the left end of the main frame of the motor is perpendicular to the right end of the rotating shaft, the right end of the rotating shaft is mechanically connected to the inside ofthe main frame of the motor, the right end of the rotating shaft is connected with the middle end of the front cover, and the bottom of the main frame of the motor is fixedly connected with the rearend of the motor fixing base by the hexagon socket screw. The efficient radiating dust-proof motor provided by the invention effectively improves the effect of cooling and radiating by structurally setting a radiator and mounting an exhaust fan and an air suction fan, effectively reduces the wear between the parts by the mechanical transmission of the transmission device to reduce the pulling force, and reduces environmental pollution as the dust removing device may effectively humidify and filter the dust and exhaust gas generated by the motor during work.
