Description

Motor air intake filter equipment

Technical Field

The application relates to the technical field of ventilation and cooling of motors, in particular to a motor air inlet filtering device.

Background

The motor is an electromagnetic device for converting electric energy or signals according to the law of electromagnetic induction. When the motor is switched, loss is caused and heat is generated. If the loss occupies a large area, more heat is generated, and the energy conversion and the service life of the motor are seriously affected. Therefore, the cooling of the motor has important practical significance for the stable operation and the working efficiency of the motor.

The motor cooling is mainly divided into surface cooling and internal cooling, wherein the self-cooling mode in the surface cooling is realized by directly sucking cooling air from the atmosphere by means of the structure of each part of the motor, natural convection is formed, and heat is released into the atmosphere through the inside of the motor. The form has the advantages of simple structure, zero consumption, reliable performance and most common application.

Currently, a conventional self-cooling open ventilation structure is shown in fig. 1. External air directly enters the motor from the position of the air inlet at the end A. This cooling form has a simple structure and low consumption, but at the same time has a non-negligible problem. Firstly, because the cooled air is directly introduced from the atmosphere, impurities such as sand dust, small broken stone and the like in the atmosphere are likely to be introduced into the motor together, so that the inner cavity of the motor is dirty, the motor assembly is polluted, and particularly, for structural members close to the air inlet side (namely, the end A side), the pollution and the damage are relatively more serious; the second is that although the erosion of most rainwater can be obstructed, but a small amount of rainwater can be absorbed inevitably, the damage to the corrosion can be caused to the metal material of the motor, and third, the cooling effect of the motor can be greatly influenced by the strength of convection depending on the cooling path formed by air convection, and especially the difference of temperature differences between two sides is larger for the motor with longer length, so that the power density of the motor is reduced, and the actual using effect of the motor is influenced.
