Copper Brush in DC Motor | DC Motor Brush | Commutaor Brush
In this video you will get to know about the Copper brush which was used in Commutation process before carbon brush existed. Carbon brush repair is easy and cheap as compared to copper brush . Therefore it is used in every type of motor and generator. So watch this video on my channel Science Engineering Technology Simplified to know how motor and generator were made before carbon brush existed.
Reference - Patent number 475668 / Year 1892

In this Series of videos i will be making videos on Nikola Tesla . Currently I will be making videos on Nikola Tesla inventions . There are about 300 Nikola Tesla Inventions but many of them are still classified by the government so we call them Nikola Tesla Lost Inventions . In future I will also try to bring videos related to Nikola Tesla Lost Inventions if the government declassifies them . So Dear viewer kindly Subscribe to my channel Science Engineering Technology Simplified if you want to Learn about Nikola Tesla Inventions in detail .
