Default Re: industrial buffer help

thanks for the heads up, but that craftsman is really 3/4hp. craftsman notoriously applies creative hp ratings to their products. Some things that help me get the full picture (usually have to tell by the current rating):

Power (in Watts) = Voltage x Current x efficiency (usually assume around .6)= 115V x 8A x 0.6 = 552W

conversion: 1hp = 746W

552W/746W = 0.74hp

general rule of thumb, you can get around 1hp/10A. if i see a motor that says it draws 15A, i ballpark it without actually working any numbers that it's a 1.5hp motor.
