Powermatic 66 with router table and a DC

[Toddler]

Saw this on Craig's list. Seems like a great price.

Wish I had space and 220V

And 3 phase power...

 

[Toddler]

Missed that. Sorry

 

[Travis Porter]

Easy miss on the 3 phase. I didn't see it either.

 

[Jon]

what is 3 phase power?

 

[Travis Porter]

Normal house current is single phase. Industrial/commercial is 3 phase power. Have to have a phase converter or have the power company bring in 3 phase power (as well as change out electrical panels) to use it.

A little bit I found about about 3-phase power, because I really didn't know much about it either.

Three-phase is much more costly to install, but is much more efficient for high horsepower motor loads.

Have you ever done any singing in rounds? ''Row, row, row your boat, merrily, merrily....'' When the first group reaches merrily, the second starts ''Row''. Eventually you have 3 different groups singing the same thing at different times. So 3 phase. In addition to the familiar sine wave of single phase, 3 phase has a second phase starting 120 degrees after the first, and a third phase at 240 degrees.

The big advantage to 3 phase is that motors can be smaller for the same horse power. Just as a single phase AC motor is smaller than a similar DC motor, so a 3 phase motor is smaller than a single phase. Airplanes use electric motors with even more phases where weight is even more important then size. In factories, it is common to have many high loads, and most of them use 3 phase motors and 240 or 480 volts.

Also, motors dont need a capacitor to start on 3 phase

Single phase 120/240 volt service at 100 amps can provide 24000 watts of power.
The largest single phase motor available is approximately 10 HP.

Typical 3 phase 120/208 volt service at 100 amps can provide 35984 watts of power.
3 Phase motors are available up to 3000 HP.

Interesting. I don't know that I have seen many if any single phase motors above 5 HP. 100 Amps at single phase would be a big set of wires straight to a motor. For my shop at 100 amps, I ran #4, but the size to a machine would be even larger IIRC.

I don't even have 220V in my garage right now, but think I'll get one of these in my basement next house. . .
3 Phase Converter Info- Sales- rotary phase converter, static 3 phase rotary converters.

Seems like buying two big tools used will pay for it.
