yea basically that is the deal without gettin all sciencey and stuff,,,,,3 things for an alternator/generator to produce voltage: 1 magnetism,put power to slip rings/brushes on rotor,theres your magnet(rotor),2,motion,,,,yea the engine is spinnin the rotor,,3 , a conductor,,,,hopefully your stator is good
,and voila u got juice!!,,it just takes extra "motion" to allow the magnetism to build up enough tell the voltage regulator, Im rotor,and im turning,please keep sending power to the brushes,,and give me alternation to recharge my friend mister battery :wink:actually,power doesnt get sent to the brushes,usually,,until the volt reg senses the rotor turning ,,thats the "residualmagnetism",,,i can "see" on a multimeter,when checking a generator,ac 110,,,that if ihave "no 110",,and i have a reading of 4 or 5 volts ac when its running,and idont have power on the brushes cause of a problem,,that 4-5 volts is produced,just by the motion,and the conductor,that 4 or 5 volts usually goes toan "exitation" circuit,,,,,kinda same deal in an alternator
