Abstract

The utility model relates to the technical field of automobile parts, and discloses a high-stability automobile air conditioner air door actuator motor which comprises a motor aluminum alloy shell, a motor body is fixedly installed on one side in the motor aluminum alloy shell, and a motor rotating shaft is fixedly installed at the output end of the motor body. The motor rotating shaft extends to the outer end of the motor aluminum alloy shell, a protective shell is fixedly installed on the side, away from the motor rotating shaft, of the motor aluminum alloy shell, and cooling fins are fixedly installed on the side, away from the motor rotating shaft, of the motor body. According to the high-stability automobile air conditioner air door actuator motor, the heat dissipation fins are fixedly installed on the side, away from the motor rotating shaft, of the motor body, the heat dissipation area is greatly increased, when the motor body works to generate heat, the heat is rapidly conducted to the heat dissipation fins, the heat dissipation fins can rapidly dissipate the heat into the surrounding air, and the heat dissipation efficiency is improved. The temperature of the motor body is effectively reduced.
