Problems solved by technology

[0004] In the above-mentioned related technologies, the inventor believes that when the motor is used for a long time, the external flocculents tend to adhere to the side of the fan blade cover facing away from the fan blades, and it is easy to reduce the air inlet of the fan blade cover, so that the fan The wind force blown into the axial air hole is reduced, which leads to poor heat dissipation effect of the motor

Abstract

This application relates to a three-phase asynchronous motor, which relates to the field of motor technology, including a body, a rotating shaft rotatably connected to the body, and an end cover arranged at one end of the body. A fan is coaxially connected to one end of the rotating shaft, and the fan rotates in the end cover. A number of air inlets and air outlets are provided on the two end faces of the end cover, the air outlets face the side wall of the body, and the rotating shaft can rotate forward and reverse in the body. In this application, by setting up a fan, the forward rotation of the rotating shaft is used to bring the fan forward to blow the wind from the air inlet to the air outlet, and the reverse rotation of the rotating shaft is used to drive the fan to reverse, and the wind is blown from the air outlet to the air inlet to reduce the adhesion The flocculent debris on the side of the end cover facing away from the fan is blown away from the air inlet, reducing the accumulation of flocculent debris on the air inlet, thereby increasing the wind force blown by the fan from the air outlet, thus having the advantage of improving the heat dissipation effect of the motor .

Description

technical field [0001] The present application relates to the field of motor technology, in particular to a three-phase asynchronous motor. Background technique [0002] At present, the three-phase asynchronous motor is a kind of motor in which the rotor and the stator rotating magnetic field rotate in the same direction and at different speeds. There is a speed difference, and it is suitable for various electrical equipment and has a wide range of applications. [0003] Related technologies such as the publication number CN102790471A disclose a new type of three-phase asynchronous motor, which is characterized in that it includes a stator, a rotor and a housing. In the casing, the rotor is set in the hollow position of the stator center through the rotating shaft and the sealing casing. The sealing casing extends from one side of the rotating shaft and is connected with a fan blade. The fan blade is provided with a fan blade cover. There is an air inlet at the end of the c...
