What is the difference between an alternator and a generator?

An alternator can be called a type of generator. Both alternators and generators convert mechanical energy into electrical energy. The main difference between them is in regard to what spins and what is fixed. In an alternator, electricity is produced when a magnetic field spins inside the stator (windings of wire).

Likewise, what is meant by brushless excitation system?

Brushless Exciters. WEG Electric Machinery's (WEM) brushless excitation system consists of a high frequency AC generator (armature & field) and rotating rectifier bridge. Rotating rectifier redundancy with detection of diode failure which in operation allows for more convenient maintenance intervals.

What is an exciter for a generator?

The essential part of this principle is the magnetic field. The magnetic filed is produced from a DC power source from an Exciter that is part of the generator system. The rotor is a rotating electromagnet that requires a DC ( Direct Current) electric power source to excite the magnetic field.
