this is my first time posting here also I'm very new to electrical engineering. i am building a pull cord (like a lawn mower) human powered generator and I'm looking for ways to increase the current output.
since i want the device to be as small and portable as possible i had originally bought a basic gimbal motor that is generally used for drone and thought i would turn it into a generator.
i bought the motor that had the lowest kv rating (31), since thats how many rpms it would makes per volt. i figured if i reverse that and treat it as a generator then i would be able to get a high power output at low rpms. i thought since p=iv then if i have a high voltage reading then the current wouldn't be an issue.
however although i was able to get a modest voltage reading (around 30 volts per pull) i didn't take into account that most of that would be lost to heat as i go and charge a pair of lipos. what i need is a way to increase the current so i can charge the batteries faster. I'm thinking maybe if i can increase the torque that would help. I'm trying to be able to charge the batteries as fast as possible, even if it requires more work.
is there a way to increase the current of a generator? or are there already of the shelf motors that have high current? what if i charge ultra capacitors from the generator instead? i know they can charge faster so will they increase the current?
i am very new to all of this. anything helps!!! :)
