Collector Ring Insulation Molding Material

In the electrical rotation conduction and signal rotation transmission, a system in which a static object and a rotating dynamic object are in good contact is required. The device for power rotation conduction or signal rotation transmission is called a slip ring (or slip ring) system. . The collector ring can choose different materials in the design and manufacture. The first consideration for selecting the material is the realization of current density, environmental adaptation and mechanical performance guarantee. According to the configuration equipment use conditions, target number of revolutions, equipment design life, product requirements and maintenance cycle factors such as comprehensive consideration. Collecting rings are assembled, molded, bridged, closed, open and many other structural forms.

Collector rings based on traditional experience generally have tin bronze, silicon brass, stainless steel, carbon steel, precious metals. When designing the collector ring system, firstly determine the material of the collector ring according to the conditions of use of the machine. There are also many types of collector ring insulation molding materials. Epoxy molding compound, phenolic molding compound and BMC molding compound are generally used. BMC unsaturated polyester mold plastic is unsaturated polyester resin adhesive, glass fiber reinforced material, add part of the filler, made of unsaturated poly glass fiber reinforced plastic. BMC molded plastic products have low shrinkage, high dimensional accuracy, bright color, and good gloss. BMC molding compounds have high strength, flame resistance, high pressure resistance, corrosion resistance, and their excellent arc resistance. The tracking index of creepage resistance is located in the insulating material. Forefront. BMC molding compounds use injection molding or compression molding to produce slip rings. Simple processing, light weight, high production efficiency, one-time rapid solidification molding, very suitable for large-scale production of collector ring. Therefore, it is an ideal insulating material for producing large collector rings.
