Needing a new plunge router. Any ideas on which brand is best between triton, bosch, and porter cable. Need a 3 1/4 hp. Thanks
Actually, you divide by 746, and the nominal voltage these days is 120VAC. That gives you 1800 watts, and 2.41 HP. Of course, that is just power consumption with a very basic calculation. Doesn't take into account power factor, motor efficiency, and such. And no, they don't jam metal rods into the motor to measure peak HP.. I won't even go further down that trail.I have several routers and I like the Triton best and all of my routers are plunge types.
By the way, manufacturers and folks always talk of 3 1/4 hp routers and 6.25 hp shop vacuums. Years ago there was an interesting article in Fine Woodworking Magazine. The article said those advertised power is peak horse power. It said when the motor is running and you jam a metal rod into the motor, the instant prior to it exploding is peak - when the motor is drawing the most power. It said to calculate actual horse power you multiply the volts (110) times amps (15) = 1,650 and divide by 1,000 you get the actual horse power 1.65 - about 1 5/8 hp.
