Ditto on the comments about highly inflated h.p. ratings. I think Sears started this, setting off a claimed-horsepower war. Annoying because it’s really deceptive. Amperage is the surest indicator of power, though other factors such as efficient design and materials (copper windings vs. aluminum, for example) can be a factor. Universal motors seem to get their horsepower via extremely high rpms, which is one reason they are so loud. Interesting how they will audibly drop in pitch when loaded. I had a DW 735 that screamed like a banshee (fault of the blades, though, not the motor). Any fairly wide hardwood board would make it lug down until I thought it would go up in flames. Probably would, too, if you kept applying that kind of load to it. Have to admit, though, that it did leave silky smooth surface (until the blades would get nicked). If you want to suck dust with real authority, you have to go to induction motors, which of course means dust collectors (but I admit I have a mini dc from HF that has a universal motor—dedicated to the ts).
