More info about circular saw quiet

The circular saw has a universal motor in it, and this type of motor is extremely noisy. Something like a radial arm saw or a table saw uses an induction motor instead. Induction motors run only on AC power and do not use brushes – that is the main reason they are so quiet. If we compare this with a universal motor with 3/4 horsepower output, we see a speed increase of about 15,000 RPM, a size reduction to about 6″ long x 3″ diameter and a weight reduction of greater than 85%. The weight difference is huge – a circular saw would be almost unusable if it contained an induction motor.

An interesting experiment would be to run your skil type saw on dc, and see what noise remains. As someone said in another post running the saw on rectified and filtered ac will give too much power to the motor. You need something less than 100 volts dc to run the saw at the same power level.
