110 /220 motor

[2mJps]

I have a 3hp motor on a lathe the guy that had it died so i dont know much about it. He was a machinist and i cant belive he didnt use this like it was but its had a cord with just 2 wires 110? I needed to use it so i put a plug end on it and used it. I didnt have to put it under much of a load it worked ok but i found out it wouldnt start in highgear. I thought i would wire it for 220 and try it. I pulled the motors box cover and it isnt wired like the diagram for 110 or 220 and its hard to tell if the wires are all still labeled. The motor is old there is 2 capasters in the box and it has a centrifugal starter. Is there any way to wire this for 220 with out all the wires labeled?

Got a multi meter?

Yes l do.

Make sure to hookup a ground wire to it

you can ohm out the leads to figure out which one goes to which winding

There are 10 wires comeing out of the motor and the wireing diagram shows 10 but it dosent show the capasters.

Sounds like a dual voltage 3 phase motor where someone has tried to use capacitors to keep it running on single phase power. But, a typical 3 phase motor has 9 leads rather than 10. Is one of the wires by chance attached to the inner surface of the junction box as a ground?

Pictures of the inside of the junction box and the motor nameplate would be helpful.

Read the first post again, and noticed there's a centrifugal switch so its not a 3 phase motor. Only other type of motor I've seen with that many leads is a 2 speed motor. Definitely need pics.

Can you take the motor, along with some doughnuts, into an Electric Motor Shop and ask them for some Tech Assist?

I will try to take a picture.

I only know of one place and its 70 miles away. This motor weighs around a 100#. I may replace it with a 3ph motor but it would be nice not to have to start the converter when i wanted to use the lathe.

 

[wyliesdiesels]

until you post pics how about a brand and model number?

you really havent given us much to go on here...

Ive never seen a 10 lead single phase motor.

Im wondering if this is a 9 lead 3phase and the 10th lead is ground

Are you sure it has a centrifugal switch?

A picture would be worth a thousand words.

Three Phase motors need three phase power, until you get 3 phase into your shop you will have to deal with the phase converter or replace the motor.

My advice, Deal with it.

Its a Westinghouse ALDP. IT has 1 phase 110/220 with a 110 wireing diagram and a 220 diagram. Both show 10 wires.

I have a lathe,shaper,and a mill that i run off of a rotory converter i built. I have another small lathe thats single phase. I dont mined the converter but its handy to just turn the lathe on and use it.

heres an old thread on the same motor

I got to thinking about it today and wondered if it was wired for 220 and some how the neutral was hooked up but not through the cord.What was bothering me was alot of the wires didnt have any numbers and the switch was also wired through the motors box to use forward and reveres.The cord that ran in to the box had 3 wire but looking at both ends only 2 were used the other one was cut off were it couldnt be used.I look at the wires and made a note of what wires i could see the numbers on. I am sure that its wired for 220. I dont understand how it was wired to the shop. I am going to try and talk to the guy that may have unwired it when it was moved.Thanks for every ones help.

It's been a while since I worked on an ALDP motor, but if I remember correctly, the wiring is generally as follows, which you probably already know from the wiring diagram on the motor.

For a 115V connection configuration, (Line (HOT) - 1 & 3); (Line (NEUTRAL) - 2 & 4); (5,6 & 10 tied); (7, 8 & 9 tied).

For a 220V connection configuration, (Line (HOT) - 1); (2 & 3 tied); (Line (HOT) - 4); (5 & 10 tied); (6 & 7 tied); (8 & 9 tied)

What would really help in identifying the individual conductors, as others have said in this post, would be if you could ohm out the conductors and then post those ohm readings. As others have also stated, pictures of the wires, the wiring diagram and the nameplate would also be very helpful.

Just my two cents.

A vfd is another relatively cheap and very easy way to get 3 phase power. Plus it would provide speed control
