Problems solved by technology

[0004] The ventilation structure of the existing motor is single, the air path structure is unreasonable, and there is no good heat dissipation effect. Therefore, adding a windshield, changing the air path structure of the motor, and increasing the air volume of the wind passing through the stator and rotor of the motor can effectively reduce the temperature of the motor. l thereby improving the performance of the motor

Embodiment Construction

[0017] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0018] Such as Figure 1~2 As shown, the present invention mainly includes an outer ring 1 and an inner ring 3 , and the inner ring 3 is located in the outer ring 1 .

[0019] The outer ring 1 and the inner ring 3 are connected into one body through the air guide ring 2 at the left end, the air guide ring 2 is trumpet-shaped, and the diameter of the air guide ring 2 gradually decreases from left to right. The large-diameter opening end of the air guiding ring 2 is the air guiding outlet, and the small-diameter opening end of the air guiding ring 2 is the air guiding inlet. The small-diameter open end of the wind guide ring 2 is the same diameter as the inner ring 3 .

[0020] The included angle A between the side wall of the wind guiding ring 2 and the vertical line is 0-90°.

[0021] The outer surface of the outer ring 1 is provided with a pluralit...

Abstract

The invention relates to a wind shield for an inner fan structure three-phase asynchronous motor, in particular to a wind shield for an inner fan structure three-phase asynchronous motor with the center height of 315-4 level, and belongs to the technical field of motors. The wind shield comprises an outer ring and an inner ring. The inner ring is placed in the outer ring. The outer ring and the inner ring are integrally connected through a wind guiding ring at the left end. A plurality of connecting holes are formed in the outer side surface of the outer ring and are distributed in the peripheral direction evenly. The wind shield is reasonable in structure, a wind path is smooth after motor rotates, wind amount through a motor stator and a rotor can be greatly increased, motor temperature rising can be greatly lowered, motor radiating effect can be greatly improved, motor efficiency can be greatly improved, assembling is convenient, and the assembling mode of an original motor is not changed.

Description

technical field [0001] The invention relates to a windshield for a three-phase asynchronous motor with an inner fan structure, specifically a windshield used in a three-phase asynchronous motor with an inner fan structure whose center height is 315-4 poles, and belongs to the technical field of electric motors. Background technique [0002] Motor burnout is caused by the cumulative temperature of motor windings or bearings exceeding the temperature limit that the motor can withstand. As the temperature rises, the performance of the motor will decline significantly. Therefore, controlling the temperature rise of the motor in the motor industry is a standard for considering the performance of the motor. [0003] There are many ways to reduce the temperature rise of the motor. Among them, changing the ventilation path of the motor is a simple way to reduce the temperature rise. Therefore, improving the ventilation path of the motor is a way to prevent the motor from overheatin...
