Fan blade fans for motor cooling

Abstract

The invention belongs to the field of motors, and particularly provides a blade fan used for cooling the motors. The blade fan aims to solve the problems that existing servo motors are low in heat dissipation efficiency and dynamic balance parts of motor fans easily fall off. The blade fan comprises a plurality of blades and supporting rings arranged at the two ends of the blades and used for fixing the blades, and the extension surface of each blade points to the rotation axis of the first supporting ring. The blade fan further comprises a balance disc for improving dynamic balance of the blade fan and further comprises a drive motor connected integrally and used for driving the blades to rotate. When the blade fan cools the servo motors, the servo motors can be well cooled during forward rotation and reverse rotation. Because the blade fan is provided with the balance disc for weight balance, the motor of the fan can be operated stably in the work process and avoids vibration.

Description

technical field [0001] The invention belongs to the field of motors, and specifically provides a blade fan used for motor cooling. Background technique [0002] When domestic and foreign servo motors are cooled by forced air cooling, axial flow fans or eddy current centrifugal fans are usually used as cooling air sources. Existing shaft diameters (Φ8-Φ12mm) of the same power are generally small. In a working environment with high vibration, the vibration of the fan itself will also increase, thereby reducing the service life of the fan. At the same time, the existing axial flow fans and vortex centrifugal fans have forward and reverse rotation requirements. In practical applications, many operators have not noticed this problem. The fans are often in the reverse operation state. At this time, the air output It is only one-tenth to one-fifth of the actual air volume, and has almost no heat dissipation effect on the servo motor, resulting in the servo motor always working in ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problems of low heat dissipation efficiency and easy falling off of the motor fan motor balance parts when the existing servo motor is reversed, the present invention provides a fan blade fan for motor cooling, The blade fan includes a first support ring and blades distributed circumferentially on the first support ring, one end of the blade is fixedly connected to the first support ring, and the blade fan also includes a balance plate , the first support ring is connected to the drive motor of the blade fan by means of the balance plate
