hey guys, i'm a young hot rod/chopper fabricator, with even less electrical experience. i've been on the forum now and then to learn a little bit about machinery, but this is my first time posting anything. i searched the forum a little bit for this, but didnt seem to find anything too specific to my situation. if you know of a thread that can help, please link me to it. thank you
so, i just got a 3HP Sharp knee-mill, when i had picked it up, i wasn't sure if it was single-phase or three-phase, the wiring was messed up coming out of the switch because of how it had been removed from the previous shop. The motor said 3-phase, but the previous owner could've sworn it was single phase.
heres what i'm working with:
heres the tag on the motor
heres the wires in the backside of the switch
heres the tag on the switch (the 'POWER REQUIREMENT' tag below has no info on it )
inside the switch
and finally, the wires coming out of the switch. three wires, coming out of the 4-wire cable..
so i think ive determined that its all setup for three-phase, right? the wires coming out of the switch is just missing one, like it had been broken or ripped out or something..
anyway, if it is in fact 3-phase, i'll need to figure out a phase converter situation.. heres what i've found so far, but i really don't know the first thing about all this..
