Raymond Garafano If the field has lost its residual magnetism you can “Flash the Field” by applying a DC source for a spell. This will provide the necessary electromagnetic field to create the residual magnetism necessary for buildup once the machine is put into operation.

Bravo davver. By, da Utenti.itali

Grazie mille

Being someone who's familiar with the 52 Delta MOS, How much did you expect to learn from attending a 3 month technical course? AIT is suppose to get you familiar with a basic understating of mechanical and electrical fundamentals (Ohms law, diesel engine operation, and using test equipment and general tools. Your true learning is suppose to come from your supervisors in the motorpools. Army generators from 5kW to 840kW are designed to operate, and support three phase loads. Some of the power consumers we used have three phase motors installed E.G Radars, Weapon Systems and Environmental Control Systems. When your setting up power grids, you want to insure that the load is as balanced as possible. This will allows the generator to spread the load evenly across all three phases. A generator that isn't properly balanced with reduce the life expectancy of the generator.

On additional note... this about the 220 VAC...In Europe (Germany), we use 220 VAC, 50Hz, If we had to use a printer or plotter from our office in the field, we would just take one of the german style extension cords, splice it into two of the three phase, and one to neutral. That will give to 208 VAC when operating in a three phase setup. the 12 volt difference is not a big deal, and because the german equipment works on 50Hz, the motors may turn a little faster.;)

NO Nuclear Damm Its Going TO KILL Us ALL

lol, I sat down and thaught about it and I think I know why the army uses 3 stages instead of a magnetic core in the exciter. earth magnets lose there field over time naturally. pushing against the north pole of an earth magnet with a northern electro magnetic field and the same with the south could potentially cause an unnatural decay at best or crush the earth magnet or at worst turn it into a projectile.

The Army use a permanent magnet generator on the 3kW, and 7.5kW generators.

@@tberry7348 There's no such thing as an earth magnet. It's called a rare earth magnet because it's made from rare earth elements.

احمد الجبوري You can communicate with me, I can help you with electrical engineering abdullahalssahan@gmail.com

MrPeterpott residual magnetism is how it self excites itself. This is why people whos generators sit for a long time have to "flash" the field. Same thing with old tractor generators. Im not real sure you know what youre talking about.

Lol wow Peter. Wouldn't be speaking with such a condescending tone when you clearly have no idea what you're talking about. Your arrogance makes me sick. Thanks for the helpful video Marc.

you´re a special kind of dum. the residual magnetic field is in the steal the rotor made of.

@@oliverroedel1111 Residual means left over, not innate. This means your "Primal, primer, primordial mover and a shaker is not so self exciting after all". What am I dumb or something not to know the meaning of residual, (I.e. left over). You know when you toss your left over food towards the dog because he depends on you. Your beloved dog doesn't have his own food. He lives off your residual left over food. Can't make his own. At least residual is not residential. I can deal with that.

@@alchemy1 residual is residual and means that METAL gets magnetic and this is resisual magnetism. en.wikipedia.org/wiki/Remanence
