ADVANTAGES OF PERMANENT MAGNET SYNCHRONOUS GENERATORS

Today, no one will be surprised by the fact that many relays and sensors, rotors of motors and generators, even in such grandiose structures as industrial hydroelectric power plants and wind turbines, use neodymium magnets in their units instead of the excitation windings that are becoming a thing of the past. Large currents through the rotor windings are no longer needed here, and sparking brushes have long been dispensed with.
