Development of a Brushless Regulated AC Generator of Radio-Interference-Free Design

摘要

The Naval Civil Engineering Laboratory was requested by the Bureau of Yards and Docks to study power generators with the object of reducing radio interference at BuDocks installations. Study revealed that brush sparking at the commutator and slip rings of ac power generators and associated exciters was a source of severe radio interference and that brush, commutator, and slip-ring wear were the main sources of all generator troubles and maintenance expense.
