unless you got some hydraulics going on like clamping or something, its most likely a spindle cooler. extend lifespan of tool and keeps the spindle thermally stable

here is the inside of my rotary phase converter for my thing, mine is only 5hp, but im just powering some 750w servos at 220v. the biggest slap in the face to the whole 3phase experience was that my 3phase servo drivers convert 3phase into 2 phase, and then back into 3 phase, but i digress. i paid $1100 cad through a source(homie) at work, but they were listed for $4000. knowing now whats inside the panel, i would have just bought the starting unit and sourced the motor separately. knowing what i know now, i would go a different route because everytime i boot my thing on, even when im doing control related shit like parameters or programs, or setting it up and debugging/repairs (its p old) i need to run the phase converter,big ol 5hp motor just spinnin, so if i spend the whole day just working on the control unit, my mom flips because it sends the hydro bill though the roof. the control unit doesnt take 3 phase either, unless you can get 3phase hydro at a good rate, id suggest doing a single phase vfd for the spindle like the other guy suggested

oh la la mr professional. i cant argue with any of your logic or reasons but yeah this is 4chan dont be a fag

here is a of my 3 phase thing, my motor is bigger than yours but same idea

ew portugase motor

but yes! you can! even you the guy who hasnt looked up shit on his own.

several ways to do it
one, is with a starting capicator, thats if you only need to run a 3 phase motor

another way it to use a normal motor, to start the 3 phase motor, then once the motor is already spinning it can run off of 2 phases as well

a vfd is definatly the nice way

this is the way im currently doing it now
this powers up my 5hp 3 phase motor, it then generates 3 phases for me and smooths them out into useable 3 phase electricidad. to just run a motor you do not need this level


running a 3phase motor or generating a third phase is not nearly ad difficult as you guys make it out to be,
