Embodiment Construction

[0013] Please refer to the attached figure 1 It is the main sectional structure schematic diagram and the attached figure 2 As shown in the left view structural diagram of the present invention, a new structure of a slip ring of a large and medium-sized winding motor, the sleeve 1 is shrunk on the shaft, and an inward special for The fan 2 for slip ring cooling, the fan 2 is fixed on the slip ring 7 through the plug 3, the bolt 4, the nut 5, and the washer 6. By installing the fan 2, the wind speed at the slip ring 7 can be increased to strengthen the cooling of the slip ring 7 and increase the slip ring. Ring 7 operational reliability.

[0014] The fan 2 is a circular fan with a plurality of blades, and a plurality of slip rings 7 are disposed within the coverage area of ​​the circular fan 2 as a whole.

Abstract

The invention discloses a new structure of a large and middle scale wound motor slip ring, which relates to the improvement of the structure of the wound motor, wherein, a fan is arranged at the outer end of the slip ring at the outermost side and is specially used for cooling the slip ring. The fan is fixed on the slip ring by a plug, a bolt, a nut and a washer. The new structure of the large and middle scale wound motor slip ring has the beneficial effects that: the cooling at the position of the slip ring is improved by installing the fan of the slip ring; both the attachment amounts of carbon powder and the temperature rise of the slip ring are reduced; the stability of the slip ring in operational process is greatly improved.

Description

technical field [0001] The invention relates to the improvement of the structure of the winding motor, in particular to the new structure of the slip ring of the large and medium-sized winding motor. Background technique [0002] At present, large and medium-sized winding motors are widely used in the cement industry. Wound motors have the advantages of starting and variable speed, but they are not stable enough compared to squirrel cage motors during operation, especially the slip rings often shoot due to high temperature during operation. In order to solve the above situation and reduce the temperature of the slip ring as much as possible, it is necessary to improve the structure of the slip ring. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of slip ring structure suitable for various large and medium-sized winding motors. This structure installs a fan on the slip ring itself to increase the capa...
