Hand Crank Generator
Hand Crank Generator
(OP)
I want to hand generate 40w for 30 seconds is this possible with a 4"dia x 1" housing
I built a neodymium motor 20 poles the windings were done by a transformer house but I was unable to remagnatize the neo's
I bought a brushless motor turns out I had to turn it 60:1 not an easy task.
Not my strong suit but I offered to help with this project..
Regards

RE: Hand Crank Generator
This is a 25W generator you can scale to the bananas.
Those generators guys sit at and crank with both hands are only about 30W I think.
RE: Hand Crank Generator
With a 6" radius handle turning one rev per second you would required about 20lb of force with a 50% efficient system.
If this is a home project you might be able to use an old drill motor gear head for a speed increaser.
