The description is contradicting. I am unsure how a 15 Amp motor designed for 120VAC can produce 3.25 HP. Can this be clarified ?

I am sure the HP measurement is mechanical power not electrical. Mechanical power in this case would be a function of torque and rotation as opposed to electrical power which is voltage and current.

Not a an electrical engineer but I can tell you that this performs as I expected it to and better. It is quieter than the old 3horse Porter Cable that we had. Not as quiet as our Festool but fraction of the price. Highly reccomend this router for heavy routing in a fabrication shop.

Every tool manufacturer has found a way to exaggerate their power ratings in order to make their products more marketable. Those 120v shop vacs that are claiming an output of 6.5 HP is case in point. They get away with it by calling it "peak" horsepower. I believe they calculate peak HP by factoring in the start up amps that it takes to get the motor going, not the running amps. Startup amps can be 3 to 4 times the normal running amps. Yes, startup amps only surge for a second or two at most, but again it's a marketing ploy.

Not sure how they calculate the HP, this might be a question for Makita. I get 2.41HP when calculating based on 120V and 15A. (Php=(eff*UI/1000)/0.746). It could be 3.25HP if the motor was 135% efficient!

I have not used mine with motor running as of yet,I have it in a Rv and used breathing machine ( c-pap) and also had a 20" box fan running @ same time,when first turned on it said it had 12.68 volts,ran both all nite (7 hrs) and when I looked before shuting off it said 12.06 volts so it didn't draw to much.....I have a 200hp O/B and it only has a 35amp alt so they don't put out much amperage,,,,,,,

It is a 120v. 15 amp, single phase motor. You will need to plug it into a receptacle that is wired from/for a 20 amp breaker. If using it as a portable unit instead of a fixed base for a router table/shaper, you will need to use an extension cord at a minimum of #12 AWG from the 20 amp receptacle.

They do not provide an amperage rating but your calculations are close. You used the right formula. The math is just a bit off. The actual formula for this is P(watts)/V(volts)=I(amps),so 150w/120v=1.25 amps. Hope that helps. Good luck.

About 6 amps is average for a 1/3 hp motor operating at 120 volt. Its a good idea to have it on a dedicated circuit or a circuit thats " known" not to have alot of load on it.

Can't say about saw but when my AC unit kicks in, the genny pops the throttle and everything just keeps humming at the higher speed. 2400 watt is peak. 15 amp is 2000 watt which is what this generator is rated for. Personally, is look a little bigger if this is the most common use. I like buffer room....your right at spec

Its rated for 22 amps. I wouldn't load with more than 15 amps, because your motor will pull more amps at start up.

Label on the motor says 1 HP. Don't know the amperage and sorry, but I couldn't look it up.

The claimed 4 HP = 2984 WThat means, at 120 V it will have to draw 25.8 Amps.Some sellers list the Poulan Pro 400E CRBB as drawing 15 Amps. At 120 V that = 1800W. That would be = to 2.4 HPNow 2.4 is far from 4Wich one is it ?L.

Ohms law says amps X Volts = Watts, So with the information provided the compressor runs on 120 volts at 15 amps will be 1800 watts. However when this compressor motor starts under a load I'll bet it spikes upwards of 20 amps probably around 30 amps so if your going to use a power inverter to run this compressor better be a good one ! At least 3600 watts at the minimum

Hello Gail. It is a 500 watt motor and goes a steady 20 mph for me. I hope I have answered your question. Tony

Reading the answer below about the 15/20 amp switchable modes, yes a 2000 watt generator would be fine in 15 amp mode. 15 amps at 120 volts is 1800 watts so in 15 amp mode, it would be fine. The power consumption shown on the sticker is 2200 watts, so you could not use a 2000 watt generator to power it in 20 amp mode.

My apologies. Forgot to mark your email as unread until I got the answer. Then forgot to look at motor. Noticed your email question as I was deleting old emails. You probably no longer need it but here is the answer. 19.5 amp, 60 HZ,110 V, single phase, power 8.2 KW. Once again, sorry for the delay. Ed

To be sure just check the output on the speed controller (in this case 15 amp) and make sure the fans doesn't exceed 15 amps. More than likely the fan will not come close to 15 amps. I don't see this fan drawing more than 1 or 2 amps.

The specs says "1240 Watt 120V electric motor" which means you got to have a minimum generator of 1240W so find a 1500W should work or just plug in a regular outlet. I plugged my in a typical outlet.

15 amp is fine as long as the rest of the circuit is not overloaded. Mine run off a dedicated circuit, 15amp, and I have no issues. You run into trouble with overloading the circuit that plug is on. Clear as mud, right? Trial and error, if you are blowing your circuits, you are overloaded.

This motor uses not more than 3 amps normal operation at full speed. At start up it can draw up to 10 amps. I rec to use at leat 12 amps power supply for an on-off operation.
