A method is disclosed for converting a commutator exciter, also called to as a DC machine, into a brushless exciter while keeping one part of the rotor as well as the stator frame of the DC machine. In an embodiment, the method also keeps the field currents and the time constants of the DC machine so that the exciter's voltage regulator may be kept. Alternatively, the magnetic cores of the DC machine stator poles may also be kept.
