When there is a small amount of magnetism left over from the last time the generator was running, it is called residual magnetism. The little bit of magnetism is enough to produce a small amount of electricity. This small amount of electricity is needed to create an even stronger electric magnet. As the engine turns this magnet moving its electric field, through the stator windings, your generator produces even more power.

Priority Applications (1)

In addition to the above shortcomings, alternators have had other difficulties when applied to use in particular applications which require high shaft speeds and high rotor temperatures are produced at such speeds. Another consideration in particular applications is that of the alternator size and weight. The design of the heretofore known alternators which satisfactorily met the required power demands normally resulted in units of prohibitive size and weight.

Dc excitation system for synchronous generator

I wasn’t very accurate in my OP. What I meant was permanent magnet generators (PMG) to power the AVR which in turn powers the exciter field for the exciter armature and rotating rectifier assy powering the actual field(maybe done with brushes on older gens?). All the generators I’ve personally been around have been Kato between 2000-2500 with PMGs mounted on the end of the rotor.

My Generator Is Not Generating, But The Engine Runs; Help!

Still nothing! Ugh! Our incredibly resourceful customer did a quick Google search and found that these symptoms are associated with a non-energized electrical field in the generator head (windings).  While the unit was running, but not generating electricity, he set the master switch to the “Start” position for 3 seconds to “flash-energize” the electrical field within the generator head. This worked!

Because our alternators and controls are designed to fit directly on specific engines and engine models of specific build configurations we are unable to sell and support alternator kits. Under certain programs involving quantity we will consider selling alternators kits under a franchise contract.

Difference between static and brushless excitation system

The purpose of an alternator is to develop sinusoidally varying alternating emf of fixed frequency. This is because the loads connected to the alternator, particularly AC motors, are designed to receive that kind of voltage only. For example, if the alternator produces a non-sinusoidal waveform and it feeds a motor, the motor will be loaded with harmonics and it will run with humming noise and increased losses.

great video very informative, thanks. Question just bought the same generator as this one, looks like you have electric start as I do(but u did not use it)?, however battery is not is the same place as a ex, where the heck is it on yours?? Input appreciated. thanks
