• What are Various Losses in DC Machine Their Working

     · In many of the machines, stray losses are considered as a convention to be 1% of the whole load resultant power. Both the mechanical and the iron losses are collectively termed as stray losses. To know clearly about these losses either in a dc motor or dc generator, the best approach is to follow the power flow diagram.
