I also had the 3612 and it was called a 1.5 hp motor, but I think that is the modern optimism. If you had asked me, I would have guessed 12 amps at 120 volts for a 1 hp motor (closer to 50% efficiency).
The 4.7 hp motors in my current shop (4 of them) each draw about 22 amps at 240 volts when they are running a machine idling, not when they are cutting, which is almost 10 amps per hp at 120 volts before the machine does any useful work. Yes, spinning a blade takes power, but not that much. Which reinforces my 12 amps per hp guess.
Hoa has some interesting examples, which I will take the liberty of interpreting and normalizing to 120 volts...
My old Craftsman had a similar rated motor (13A @120V) by Emerson. The label said, "1 HP." For what it is worth, Emerson made a lot of the Craftsman power tools until Sears went cheap, then switched to Ridgid tools for Home Depot... Supports my ballpark of 12 amps per HP
My next saw, a Delta, had a motor (Marathon I think) rated at 12.8A @120V. Its label said "1.5 HP." This sounds like one of the optimistic hp ratings. Emerson made very good motors, so I can't believe Marathon was 1.5 times as efficient. My guess is that it was closer to 1 real hp.
The motor on Jet contractor's TS is rated at 18A @120V. It is advertised as 1.5 HP. Back to the 12 amps per hp guess.
My 2HP G1029 dust collector has a motor rated at 12A @240V. which would be the same as 24 amps at 120 volts, or 12 amps per HP.
Your honor, I rest my case.
