i have car alternator with rated rpm 1500, output 14v; 43 amp. so what is the output if we double ,tripal the input rpm ?
What is the changing in output , if we change the rated rpm of dc car alternator?
Alternators are usually belt driven to run a little faster than the engine so that 1500 RPM rating would be the minimum speed that would allow the alternator to produce a 14 volt DC output with the engine at idle speed. At a the maximum engine speed, the alternator might run at 15,000 RPM. Over that speed range, the voltage would be regulated to remain close to 14 volts. If the speed is increased above the maximum, the internal voltage would continue to increase. At some point, the regulator would probably be unable to hold the voltage constant. Electrically, regulator components, the stator winding insulation or the rectifier diodes could fail. Mechanically, the bearings or the rotor structure could fail.

you would burn it out, bearings and diodes.
