Abstract

Inventia se refera la un material cupru-grafitic cu rezistivitate mica (0,1...0,3 miu omega m) si uzura redusa în exploatare, destinat confectionarii periilor electrice pentru motoare de curent continuu de joasa tensiune, utilizate în echipamentul vagoanelor de cale ferata, pentru micromotoare si compensatoare sincrone. Sunt indicate materiile prime necesare producerii materialului cupru-grafitic, principalele lor caracteristici, proportiile acestora, precum si caracteristicile fizico-mecanice si de functionare ale materialului obtinut.The invention relates to a low-resistive copper-graphite material (0.1 ... 0.3 mil omega m) and reduced wear in use, for the manufacture of electric brushes for low-voltage DC motors used in the wagon equipment rail, micromotors and synchronous compensators. The raw materials needed to produce the copper-graphite material, their main characteristics, their proportions, as well as the physico-mechanical and operating characteristics of the obtained material are indicated.
