Like every one else has said, based on the amperage, it sounds like a
real 2HP motor. Referencehttp://users.goldengate.net/~kbrady/motors.pdf

Quick rule for estimating the real HP of single phase induction motors -
the fixed speed motors used in table saws, jointers, lathes, drill
presses, etc. At 120 V, it's about 10 amps per HP - at 240 V it's about
5 amps per HP. Note: any spec that says "peak" or "max" or "developed"
HP is a lie.

A few days ago someone asked about lathes. A link was posted referring
to Griz G0462. Then went on to say it's not 2 HP but more like 3/4 HP.
Is the 2 HP listed on Griz site just an exaggeration? I've been
thinking about getting that lathe for a while now.

The other thing to do is actually read the nameplate on the induction
motor. For example the old "3HP" crapsman saws said 1.5 HP on the
motor name plate. Of course what you get out of the motor may not be
what the nameplate says. But it's more likely the name plate data
was specified by manufacturing/engineering rather than marketing so
you'll likely be closer.
