wiring an electric motor
I have a small lathe I need to wire a 1/2 hp electric motor to. I would like to know if anyone knows how to wire the motor to a forward and reverse switch and to the power supply

is it a reversible motor?
how many leads and what are they numbered.
most motors have a wiring diagram on them or in the peckerhead to show you how they need to be weired for different hook ups. take a look.

unless.......you are you reffering to the comment in the previous post here?
as in peckerhead. If you are not kidding, that is a generally accepted term for the termination enclosure on a motor. (at least to most I have dealt with.)

I've never heard that term before and laughed out load when I read that.

I really do not know where the term came from but it is a very common term in the circles I travel. It still is a bit embarrassing when in mixed company but that is sometimes what it takes to communicate. When in Rome, you speak Italian.

nap beat me to the next question. I will add to it.
Can you list ALL the model and part numbers from the motor and lathe
And HF catalog numbers.
Name of lathe.
Does the lathe have a reverse switch ?
Are you replacing an old motor ?

The old motor went bad so I am replacing it. It was a Dayton 1/3 hp fan motor someone rigged up to the lathe before I got it. The Chicago Electric motor I bought is Model 36549. The lathe is a South Bend and It does have a forward and reverse switch. It's a Cutler-Hammer switch box

I cant find a chicago electric web site. the harbor freight web site has a manual, but the electric dwg is about as bunk as it gets. And I do control work for a living.

from Ray
The Model # of the Chicago Electric 1/2hp motor I bought is: 36549. The lathe I have is a South Bend and the switch box on the lathe is a forward and reverse switch, a Cutler-Hammer switch box.

--------------------
Ray, how many contacts does the switch have and can you diagram the interconnections when in the "rev" "off" "for" positions for us(or is it only a 2 position switch? plus an on off switch). That is critical to the correct connection.
Once I have this I can give you the correct connections.
A model number may allow those here to find the info (if available).

motor wiring
I can scan a drawing I made of the switch leads, motor connections etc, but I dont know how to get it into this forum, anyone know?
The switch itself is already wired internally, the leads coming out of the switch box are like a regular power cords. There are 2 separate cords coming out the back of the box, each contain a black, white and green wire. The front of the box has a switch, it turns left for reverse, top (0) for off and to the right for forward.
I could'nt find a website for Chicago Electric either, The drawings they give in the manual only show how to wire the pecker head for clockwise or counterclockwise, separately. It doesnt show how to wire to a switch either. I called the tech dept and they didnt have a clue.
There are 4 pin connections in the perker head. Pin 2 and 3 have nothing attacted. pin 4 has a black and white wire attached coming from inside the motor. pin 1 has a red and orange wire attacted to it also coming from inside the motor.

You can use photobucket or other image hosting sites and give a link.
Do the pins connect to anything (I would guess on the backside of them) or are they simply terminal posts to allow the wiring to attach to?
I'm not talking avbout the read,ornage, white, black wires coming from inside the motor either. Is there any (presumably permanent) connections that lead into the motor as well connected to any of those pins?
I have to assume there is because in the different configurations of wiring, there are times where the external power (specifically the neutral) is connected to a pin that has none of the internal wires connected to it. But check it out to be sure
Toss in the model number of the reversing switch if you have it as well..

Read this thread for help on wiring a drum type reversing switch.
http://forum.doityourself.com/showthread.php?t=271914
I myself have wired one on a lathe.
For that motor, you need to switch power to the motor, and switch the red and black wires to change direction. P4/White are one side of the run windings, P1/Orange are the other.
Without knowing what is going on in the control box, we are at an impasse.

It is no bigger.
Plus showing the cables just leaving the reversing switch is no good. We need to know what is going on inside. Likely though, you will need to rewire the reverser, as there is no means on 4 wires to control power and direction (the greens are to be ground, so if someone used them for a power lead, they did wrong).
