I am attempting to replace the motor on a lathe I just purchased. I came across a really cheap motor with (pic related specs). But I have no idea how to wire it to do what I need it to do, I haven't even been able to test that it works.I just need it to run clockwise wired to a double pole switch.
This is what I am looking at.
>>1955463Take another picture from farther away. Where are those red and black wires leaving the motor cover going?
>>1955470they go to nothing right now, just loose wire
>>1955478Well shit apply mains and see if it spins.
>>1955483tried that, breaker went
>>1955490Instantly? Did the rotor try to move at all?
>>1955463That looks like a 3 phase motor.
>>1955500instantly.There was an additional black wire, yellow wire and green wire connected to the spade connectors, but they also led to no where, so I removed them to try and start fresh
>>1955517You're going to have to give a better picture of the wires behind that cover piece to make sure there isn't something stupid going on. Otherwise, the field windings are shorted and its pretty much fucked.
>>1955517anon please post more pictures of the motor. Single phase 120v AC motors sometimes require capacitors to get started, and would explain the "extra?" wiring you found. If you have a multimeter check the resistance of the winding wires, they're the ones connected to the big bundle of copper windings. It should measure at least 10 ohms and probably should be a lot higher. If it's less than 10 ohms then the windings are shorted to ground and the motor is trash. I should add that i dont know if 10 ohms is correct, i just got that number from ohms law and the volt amp ratings.
>>1955501really how can you tell? did you read the plate in the first picture where it says 115v which is always single phase? or did you pull something out of your ass?
>>1955478take a picture of the whole motor like you were asked to.
>>1955463another tard who can't use google to save his life.here you go tard. served up for you.I image searched the model number and the words general electric then removed letters or numbers at the end of the model number until results came up that showed the motor. as home simpson said >never try
>>1955463full size picture idiot
>>1955909that's a different motor. just look at the HP rating. but yeah, it should be the same type of wiring/connections
>>1955909So does the hot wire go to both 2 and 3?
What kind of shaft connection does it have? Might be unusable if you reverse it. If the motor connects with a belt than you could just flip the motor around.
>>1955909Jesus fucking christ i HATE electrical engineers. wtf are those symbols even supposed to mean? >Blue (5) is capacitor?>White (4) is half of a switch to nothing? Thermal protect?>"HI" (3)[A] wtf is this? is it trying to say it's 1HP OR 1/3HP? wtf do you need the "A" there if it's already labeled "3"?>"LO" (2) wtf AGAIN? does ungrounded line mean L1? are they fucking calling neutral a "LINE"?Electrical engineers need to be fucking culled.
>>1956258Yeah that really is a fucking shit diagram. The best i can tell is that the "ungrounded line" (maybe neutral?) can be switched from either stud 3 or 2 to make the field winding 2 or 3 pole (~1800 or ~1200 rpm). Blue and white must go to the start winding then since those are the indicated wires to switch direction with, while the field winding is permanently wired. (The polarity of either winding can be reversed to change direction, but usually one is hard wired)
>>1956216wtf is this? We need to see BEHIND the little panel with the lugs to get an idea of the connections
>>1956210anon. please. for christ's sake. you see the nuts with numbers on them? Move the fucking wires so that we can see them.
>>1955463Back cover connections for Most GE motors. The inside connections wire color may differ by motor type.
>>1956258worst diagram ever to be honest
>>1956414this wiring pictogram is infinitely better than the newer one. The new one looks like they're trying to mix in actual wiring schematics and just confuses things.
>>1955501Its a single phase 120 v.
Tie your line to 1 and load to 2 or 3 depending if you want higher or lower rpm
>>1956210How many amps is your breaker? Motor probably works fine but it is rated at 11.4 amps. Inrush current (current spike that happens right after cold start) is going to be higher. You probably have a 10 amp breaker so it throws it immediately. Go to your breaker panel, find a line with a 20A breaker and plug the motor in to that.>>1956258You seem rustled.
>>1956258non standard symbols. probably it was a mech cuck who did
