RMS Watts is in the same silly season class as Sears and some others "Peak
Horsepower" rating of electrical motors.

REPLY: by Bill W6WRT
Nothing wrong with rating peak horsepower in the sense of power for a brief
period. Kind of like ICAS rating vs CCS rating.

Whether they do it accurately or not is another issue. I have no idea and
don't much care.

I read: a 1 hp electric motor, such as on an electric lawn mower, "if over loaded" (tall grass) can produce 3 hp (drawing triple the current) until the windings heat enough to increase their resistance, then 1 hp will be the most it can produce and this is not the property of a internal combustion engines. Is this not correct? I think this is the property of series wound and PM field motors only. (from school)
