Well, I got my new Leeson 3 something HP motor installed on the cyclone, I bought a tester and determined that the amp draw at full speed all gates but one closed was 17.2 amps continuously and the outlet read 240V, according to the tester

Julio,
The motor you have is probubly around 3 HP not know in the losses in the motor It's hard to tell exactly But here is how you can rate the comtinuous HP of any motor.
HP = Volts x Continuous amps/ 746 (Convert watts to HP) x effecncy.
Assuming 30% losses due to copper losses, windage, friction and depending on the air gap between the stator and the rotor you would ge the following.
230 x 15/746 x .7 =3.2 HP
if I plug these numbers in 240 x 17.2 /746 x .7 I get 7.9hp??
This cant be right?
