(And please don't get into the calculations of how many amps go into a hp.
For normal motors it is approximately 22a; for expensive high efficiency
motors maybe as low as 16a. It is never 14a, and HF does not use expensive
high efficiency motors; it is probably a tad more than 1hp. And that
assumes it actually draws 14a; an uncertain issue.)

I am selling a canister DC with a real 2hp motor; asking $225. Two people
have offered $200; for that price I will scrap it and save the motor in case
my TS motor ever calls it quits, since the motor alone sells for $300.

Anybody got any links or something where I can research that? I
confess I'm not well-versed in motors as I used to be, but everything
I've ever been taught says if it pulls x amps on y number of volts,
it's using xy watts and therefore xy(cf) horsepower. How is horsepower
measured in this case?

740 Watts to the horsepower


746 Watts to the horsepower
