A dust-proof asynchronous motor for a fan

Abstract

A dust-proof asynchronous motor for a fan belongs to the technical field of asynchronous motors; it includes a motor box, the motor box is an internal hollow structure, fan blades are arranged under the motor box, and an asynchronous motor for driving the fan blades to rotate is arranged inside the motor box. Both sides of the chassis are provided with air intake holes connected to the motor box. In the present invention, a lower side plate, a magnetic sheet 1, an air outlet, an ash discharge device, a guide plate, a magnetic sheet 2, a guide rod and a dredging needle plate are provided at the same time. When the magnetic sheet one rotates with the fan blades and keeps getting closer to and away from the upper side plate, the repulsive force of the magnetic sheet pair and the second magnetic sheet alternates with the downward gravitational force between the second magnetic sheet, the guide rod and the dredging needle plate. At this time, the guide plate Continuously moving up and down inside the guide cavity, the guide plate continuously moves up and down inside the guide cavity, which has the effect similar to that of an exhaust fan. Heat dissipation has a promoting effect.

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 accumulate 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.
