Problems solved by technology
[0004] The motor usually includes a stator, rotor, carbon brush, fan and motor cover. When the motor is working, the coil of the rotor will generate a lot of heat energy, and the commutator of the rotor will rub against the carbon brush to generate heat. On the outside of the carbon brush, in the prior art, the airflow blown by the fan flows directly to the rear. Since the size of the steering gear itself is small, there is still a large space between the periphery of the steering gear and the motor cover, and a large amount of airflow often flows from the periphery of the commutator. The space directly drains away the heat of the commutator, but the heat of the commutator is not effectively taken away. The airflow blown to the commutator to effectively dissipate heat for the commutator is insufficient, which causes the commutator to overheat easily when the motor is working.

Abstract
A motor includes a stator, a rotor, a carbon brush, a fan and a motor housing. The rotor is provided with a rotary shaft and a commutator fixed on the rotary shaft. The fan is mounted on the rotary shaft. The motor housing covers the rotor, the fan and the carbon brush. The carbon brush leans against the surface of the commutator. When the rotor rotates, heat is generated due to friction of the commutator and the carbon brush. An air guide board extending towards the rotor in an inclined manner is arranged on the inner side of the motor housing. The air guide board guides a part of air flows blown by the fan to turn and to flow to the commutator. By adopting the design, heat dissipation of the commutator is performed in a pointed way, so that the heat dissipation efficiency of the commutator is improved, unnecessary loss of air flows in the surrounding space of the commutator is reduced and utilization rate of the air flows of the fan is improved.
Description
[0001] 【Technical field】 [0002] The invention relates to a motor and an air compressor with the motor, in particular to a motor cover air guide structure of the motor. [0003] 【Background technique】 [0004] The motor usually includes a stator, rotor, carbon brush, fan and motor cover. When the motor is working, the coil of the rotor will generate a lot of heat energy, and the commutator of the rotor will rub against the carbon brush to generate heat. On the outside of the carbon brush, in the prior art, the airflow blown by the fan flows directly to the rear. Since the size of the steering gear itself is small, there is still a large space between the periphery of the steering gear and the motor cover, and a large amount of airflow often flows from the periphery of the commutator. The heat of the commutator is not effectively taken away by the space directly flowing away, and the airflow blown to the commutator to effectively dissipate heat for the commutator is insufficien...
