I have 4 Ametek motors and I am trying to decide which one to use or if it is even worth it? I have 2 50VDC long body (7 inch), 1 38VDC and 1 40VDC. I have found quite a bit of info. on the 38 and 40 but not too much on the 50? Should I just chuck all of these and look for a lower RPM motor? Or will one of them work? Common since says that the 50 should produce more amps. It is much heavier and has "more in it". But if I have to spin up to 400 RPMs to make any power it seems like a moot point.
Are there any other good generator solutions out there that anyone is using? I see quite a bit out there and there are several surplus places near by. I just need to know what to look for.
