초록

A control for a brushless generator is operable in a starting mode of operation to convert electrical power into motive power for starting a prime mover. The control applies AC power to an exciter field winding at a first frequency at the initiation of a start sequence and thereafter decreases the frequency of the power applied to the exciter field winding during the start sequence.

대표
청구항

A control for a brushless generator having a main generator portion including a field winding disposed on a rotor and which receives field current and an armature winding disposed in a stator wherein the rotor is movable with respect to the stator and a permanent magnet generator (PMG) having an armature winding coupled to a rectifier which is coupled to a voltage regulator wherein the generator is operable in a generating mode to convert motive power into electrical power and in a starting mode to convert electrical power provided to the main generator ...
