Brushless Excitation System - Electrical Concepts

For a machine using field coils, as is the case in most large generators, the field must be established by a current in order for the generator to produce electricity. Although some of the generator's own output can be used to maintain the field once it starts up, an external source of current is needed for starting the generator. In any case, it is important to be able to control the fiel… WebParallel Redund for Brushless EXC System - Electric machine
