THis is precisely what I mentioned earlier. RMS ratings
give what we can call the "average" output of the motor.
Peak rating means power that can be sustained for short
periods only. A motor with a peak rating of two HP may
be able to carry only a 3/4 hp load on a continual basis.
That's an important thing to know in many cases.
