I have a set of hyperspin 5 blade 28" on a GE dc PM 1/2 horse motor. On test stand, with nominal load, this motor would produce 18 to 20 volts @ 9 amps in 15 mph winds. After installation, and being connected to battery bank (much larger load), this same motor is only producing 12 to 14 volts @ 3 to 4 amps. My battery bank is taking FOREVER to recharge and never reaches 14.5 to 15 volts. Now... I do have a 2hp pacific scientic 14.5 amp 120 volt dc continuous charge 3600 rpm motor. Will this motor solve my problem? which blade set would be best suited? torque 24?
