All along, many use the motor industry, mining and the environment is bad, such as coal, mines, cement and other traditional industries. Usually the cement industry uses more winding motor, and the winding motor slip ring structures are typically designed outer slip ring and slip ring protection class is usually open type IP23. Under such as complex mining environment cement poor working conditions, a lot of dust, cinder entering into the slip ring, slip ring is likely to cause a short circuit due to excessive accumulation of dust, blasting, and even burn, a direct impact on the entire production line of production. For this reason, if a high-degree of protection of electrical slip ring structure, must be able to greatly reduce the slip ring hidden cause stagnation of production, improve production efficiency.

Cosmau overcome the deficiencies in the prior tech to provide a guarantee of the safety and reliability of the winding motor slip ring with high degree of protection structures. According to this aspect, high degree of protection winding motor slip ring structures, including slip ring chamber, characterized in that the upper end of the chamber mounting slip ring cooler, slip ring cooler inlet through the inlet pipe and the bent motor cooling connected; in the slip ring chamber cavity with a first separator and the second separator, the first separator and the second separator will slip ring chamber into the cavity left portion, and right, in the middle of the cavity portion cavity; over the right part of the cavity is provided with a slip ring cooler air inlet in communication, above the middle of the cavity is provided with an outlet on the first separator and the second separator ventilation holes; In the middle of the cavity install a fan, in the lower right portion of the cavity filter is mounted, in the middle of the right part of the cavity is mounted slip ring, slip ring is installed at the top of the stems. Slip ring mounted on the motor shaft, a cooling tube is mounted inside the slip ring cooler.

The slip ring chamber walls is a closed structure, simple structure of this slip ring, safety, the effect is obvious; in the case of heat without changing, to ensure the safety conditions and the reliability of the motor, through the slip ring structure design changes to increase the degree of protection of winding motor slip ring, promoted use of harsh working conditions.
