Dustproof asynchronous motor for fan

Abstract

The invention discloses a dustproof asynchronous motor for a fan, and belongs to the technical field of asynchronous motors. The motor comprises a motor box, the motor box is of a hollow structure, fan blades are arranged below the motor box, an asynchronous motor for driving the fan blades to rotate is arranged in the motor box, and air inlet holes communicating with the motor box are formed in the two sides of the motor box. Meanwhile, a lower side plate, a first magnetic sheet, an air outlet hole, an ash discharging device, a guide plate, a second magnetic sheet, a guide rod and a dredgingneedle plate are arranged, and when the first magnetic sheet continuously gets close to and gets away from the upper side plate along with rotation of the fan blades, repulsive force of the first magnetic sheet and the second magnetic sheet and downward gravity among the second magnetic sheet, the guide rod and the dredging needle plate are alternated; at the moment, a guide plate continuously moves up and down in a guide cavity, the guide plate continuously moves up and down in the guide cavity to achieve the effect similar to an exhaust fan, meanwhile, the guide plate continuously moves downwards in the guide cavity to accelerate heat in the motor box to be discharged from an air outlet hole, and the effect of promoting heat dissipation in the asynchronous motor is achieved.

Description

technical field [0001] The invention belongs to the technical field of asynchronous motors, in particular to a dust-proof asynchronous motor for a fan. Background technique [0002] Induction motor, also known as "asynchronous motor", is a device in which the rotor is placed in a rotating magnetic field, and under the action of the rotating magnetic field, a rotational torque is obtained, so that the rotor rotates. The rotor is a rotatable conductor, usually in the shape of a squirrel cage. Invented by electrical engineer Nikola Tesla in 1887. The entry introduces the concept of induction motor, inventor, working principle, basic structure, working method, braking method, asynchronous characteristics, specifications and fault inspection. [0003] When the asynchronous motor is in use, dust often flows into the motor from the air intake hole. In the long-term use process, due to the working environment, the outer surface of the existing asynchronous motor often causes dust ...

Problems solved by technology

[0003] When the asynchronous motor is in use, dust often flows into the motor from the air intake hole. In the long-term use process, due to the working environment, the outer surface of the existing asynchronous motor often causes dust to fall, so that the dust on the outer wall of the existing asynchronous motor The dust is serious, and it will affect the service life of the asynchronous motor in long-term use, especially for the asynchronous motor with the fan hanging on the roof, which is not easy to use. Therefore, a dust-proof asynchronous motor for fans is invented.
