Fan of asynchronous motor

Abstract

The invention discloses a fan of an asynchronous motor. The fan is arranged in a fan cover of the asynchronous motor, and comprises a circular ring type body, wherein a plurality of A type blades are arranged on the outer arc surface of the body at equal intervals; the A type blades are sheet-shaped, and the upper ends of the A type blades are arc-shaped; a plurality of B type blades are arranged on the left and right side surfaces of the body at equal intervals; the B type blades and the A type blades are same in shape, and are mounted in a staggered mode, i.e., each B type blade is positioned between two corresponding adjacent A type blades, so that the radiating effect is strengthened. A hollow layer is arranged on the inner part of the body, and the hollow layer is filled with activated carbon or other moisture-absorbing materials. According to the fan of the asynchronous motor disclosed by the invention, the integral structure is relatively small and narrow, the materials are saved, too much space is not occupied, the radiating effect in the motor is ensured because of the multiple blades, and the humidity in a motor housing is reduced because of the hollow layer filled with the heat-absorbing material.

Description

technical field [0001] The invention belongs to the technical field of motors, and specifically discloses a fan of an asynchronous motor. Background technique [0002] The asynchronous motor consists of a motor housing and a windshield installed at the end of the housing. During the operation of the motor, the rotation of the rotor and the heating of the coil will generate a large amount of heat inside the motor housing, so it is necessary to use fan blades for heat dissipation. [0003] There are two deficiencies in the fan blades currently on the market. One is that the structure of the fan blades is not reasonable enough, resulting in insufficient cooling effect of the fan blades; the other is that there is a lot of waste of materials in the manufacturing process of the fan blades, which leads to an increase in the manufacturing cost of the fan blades. , so as to reduce the competitiveness of the company's products. [0004] In addition, the asynchronous motor is ful...

[0003] There are two deficiencies in the fan blades currently on the market. One is that the structure of the fan blades is not reasonable enough, resulting in insufficient cooling effect of the fan blades; the other is that there is a lot of waste of materials in the manufacturing process of the fan blades, which leads to an increase in the manufacturing cost of the fan blades. , so as to reduce the product competitiveness of the enterprise

[0004] In addition, the asynchronous motor is full of precision components. If the moisture in the motor housing is too heavy, it will affect the working quality of the asynchronous motor and even cause damage to the asynchronous motor.
