I found this article about electric motor horsepower that answered a lot of
my questions.

  AGREED, I learned while shopping Craftsman stuff...IGNORE the HP 
rating, look at the amperage draw of the motor, there is just no way 
that Craftsman motors can put out 5HP with only 12amp draws, they rate 
them differently I forget which, startup or stall or who knows. The 
amperage is the true HP of the motor.
