Big Joe asks:


My Grizz DC is only rated at 2HP, sucking up 12 amps of 230 volt
power. Let's see, crunching the numbers, the motor is capable of
3.7HP, so it's only 54% efficient. Is that a mark of poor quality, or
just an overly honest appraisal of the motor's output?

It's probably just an honest rating. I don't really know the various efficiency
ratings for different types of motors, and I'm too lazy to look them up right
now, but I would GUESS (let's emphasize the guess again) that 60% is pretty
close to the norm.
