Well, no luck so far on finding a more efficient ac motor. They don't seem to have changed much since this old existing Hoover motor was built (back in the 50's?). Still around 4.8 to 6.6 amps at 120vac.
One thing I have neglected to do is actually run the fan with the existing motor and take an amp reading. Something I should do with the fan installed to get a more accurate amp reading but, I am reluctant to do since there is so much building involved first and, I wanted to know that I can actually use it first. I know from experience that nameplate amps are not always what the motor draws.
Even after crunching numbers and getting second opinions, sometimes it just takes, a leap of faith.
Thank you all. Sincerely, Sunour.
