Electric motors - peak vs continuous hp?
Since so many shop items are now rated by peak horsepower, such as compressors, chop saws, and even shop vacs, what is peak horsepower all about? Why is it able to exceed the calculated power which the item draws from the outlet? Where does this added "power" come from? What does peak horsepower tell us about a compressor or other item that isn't subject to unpredictable stalling forces, like a chopsaw or tablesaw where we load it down intermittently?
