this to me looks like a good motor kind of expense but good. Only thing about this one is you look down at the motor specs and it gives two amp reading a 5 amp continous and 65 amp max cut in for 12 volt should be about 150 or so rpm ? but the amps I am not sure about. I think this motor would put out 3 phase ac and I would have to 3 phase to dc retcifer. No gearing a 7 or 8 foot blade ?

This motor I am not so sure about I included it cause i have a question about the amps on it too. It sayes 6 amps pr phase and 8 leads. Look farther down it showes 8 lead hookup. I asume each one of the legs is hooked to a coil and each leg would go to a bridge retciver. You have 4 coils so you would have 24 amps max output at 2000 rpm ? voltage for this motor is not listed
It is not productive for anyone to post a bunch of dead in two weeks Ebay links and ask if they will do "X". How to select motors has been covered in detail many many times. [CLOSED]
