Hello All, I am trying to completely wrap me head around a project of mine. Here is the scenario.
I have an engine and a generator. The Engine produces 25 watts power output at 30,000 rpm.
The generator will produce 15V, 1.5A, 22.5W 10ohm resistance. at 2832rpm.
I am still trying to check my logic, but if I were to bring this motor to the 30k rpm speed, then the potential for 15V 1.5A 22.5w is there. If I were to charge a phone at 5V 750mA, this should equal 3.75W correct? Should this system be able to maintain said charge without a problem? I kinda wanted to build the system to be able to handle most things up to 1 amp.
If I am using this mainly for the charging of batteries and devices, will power use (W) stay lower? And since the output of the engine is 25W and rpm were to decrease when loaded, would the rpm decrease cause loss of power? Just trying to wrap my head around it all. Thanks!
