Wiring Diagram for 110V

[rarebear]

Here is a Novice Wiring Diagram

I read a lot of posts and I have also read a lot of diagrams and they are all wrote by smart people it seems but they fail ever time to include how a motor is wired or explain the circuits work and they seem to wite them for other electricans how know how to wire a motor and switch...

With the help of the SB Group and its Moderator David Smith I tweeked this on how to wire a Baldor six wire switch and motor..

This also work for a GE motor that changes a black and Red Wire just replace No-5-8 with the B&R

Hi There,

I wonder if you looked here before you decided to criticize us. I have posted many
wiring diagrams for people. The biggest problem is that there isn't one type of
drum switch. So, when someone ask "how do I wire this motor to my lathe?", and
doesn't provide any other information, it puts us at a great disadvantage in trying
to help.

Also, motors (especially older models) didn't always follow NEMA standards. The
motor pictured in your link does. But when someone asks "how do I hook up a six
wire motor?" and doesn't give any more information, is like someone asking a doctor
"I have a cough, what is the problem?" There just isn't enough information to provide
a definitive answer.

Personally, I'm glad you are happy with the diagram but I found it to be poorly
done and confusing (though I see it will work). This is one I just knocked-out.

Good Luck!

Webb,
I did seach here and only found a sketch that made me relize what I was not getting.. Connection two leads together.. I didn't find anything like your diagram for a dummy like me..

I don't me to criticize I just want to let those folks how to help us electricly challanged people..

I worked 10 years making wave guide parts and still have no idea how a radar tube works but I know how to build one

Most I have found show how to wire the switch but not how to wire a motor to the switch..( I guess they do but I dont undersand it)

I truly think yours is the first diagram I can read and it also helps me understand the motor wiring..I think many will use it as a resource..

Thanks

Hi There,

Normally, I don't use the Motor Diagram in these wiring diagrams but I made
that one just for you. Usually, I make them more simple, like so:

But all the necessary information is there.

Good Luck!

You have no idea how beside my self I have been over this wiring thing..

This is the second time I was wiring a new motor and it maybe the first time I relized I could not understand something no matter how much I tried to read on the web about it..

I have always been able to learn something new by reading about it.. Everything I read left me angry with myself because it scared me that I could learn how to wire a motor..

Thanks for your help, without people like you I would have to pay someone to come to my house to wire a motor...I hope some day I can return the favor......

Webb,

Excellent, clear diagrams for those of us without electrical knowledge!
Do you have diagrams for 230v and 3 phase?

Thanks,

Ron

Hi There,

I have a few simple diagrams for 115 and 230 volts but using the
Cutler-Hammer type drum switch but diagrams can be different
for different motors and different drum switches.

Single phase motors can have as little as two leads (single voltage,
non-reversible) or as many as 8 leads. Three phase motors can
have a few as three leads or as many as 12 leads. Also, there are
motors that have a terminal board instead of leads.

Drum switches can vary almost as much and I don't have model
numbers and types. I go by the internal connections of the switch
itself. Typical drum switches (that I have come up against) are
shown below:

I'm sure there are others I haven't encountered.

So, there are just too many variables involved when supplying diagrams
and putting out a "generic" diagram may lead someone into trouble. But
if a person can supply me with the necessary information, I can make a
diagram that will work for them.

Good Luck!

For single phase, 240 volt configuration:

That's why when I got my lathe and the cords were rotting, I made a careful diagram and reconnected the new cord the same as the old cords.

Hi There,

Jim, that is an interesting wiring diagram. But it illustrates what I am
talking about. First off, the motor is not NEMA compliant in regards to
the lead numbering in the motor. Therefore, I assume it is an older dia-
gram. The motor is a "Thermal Overload Protected" type motor but it is
unusual in that there are only two connections on the thermal cutout
device. Motors I usually see that have thermal overload protection will
have the T1 connection made directly to the Klixon device (Dayton,
Doer, Emerson, GE, etc.) and hence, will not work with your diagram
unless modifications are made.

The drum switch in the diagram is not identified but it looks to me like
a Cutler-Hammer type switch with the jumpers set as illustrated below:

Now in the past, South Bend Lathe used motors that weren't NEMA
compliant (usually GE motors but lathes could be ordered without the
electrics so people can encounter just about anything out there).
Also during the life of a lathe, the motor and/or controls can wear out
and "in the field" type repairs and modifications add to the confusion
on wiring a lathe.

Add to that, the individual that has picked-up a used lathe with a 3
phase motor and wants to put a single phase motor on it. Maybe he
or she has an old motor or is going to buy a new or used motor.

Now you get to see what a person is up against when a request for
wiring diagrams comes up. The diagram you posted will work for a
specific motor type with a specific switch. There isn't any
"one size fits all" answer to these requests.

Good Luck!

Thanks to everyone. I'm putting a vfd on my 10L and my Rockwell mill, therefore disconnecting my drum switches. I'll follow your recommendations & make careful diagrams of everything.

That's right webb, that motor wasn't NEMA compatible.
Well, not when I got through with it.
Of course, I *was* deep into modifications on the
motor. I wanted to power the system through the
thermal switch because otherwise it could go back to
the start windings, because in the 240 volt configuration
the start windings were not interrupted by the click
switch.

The drum switch was the standard three pole, two position,
center off type. The jumpers were added to give the
configuration shown.

I like to put that diagram up because it illustrates
how motors use the centertap on the run windings for
the start windings - on 240 volt hookup - often.

Interesting posts........I find this whole subject quite electrifying !

Hi There,

Jim, I understand wanting to have some overload protection going through
the switch. I just thought there should be some mention of the fact that
the diagram you posted was not to be used for all situations.

Some time ago, I posted a diagram for a Dayton single phase motor that
has the overload protection device (with T1 connected to the device),
wired for 230 volts and using a Cutler-Hammer drum switch jumpered for
the typical three phase configuration:

God Luck!

Absolutely right on webb's comment about that diagram not being "one size fits all."

I make it a point to never give advice when folks ask "what number wire do I hook up
to what number terminal, to make this thing run?"

All too often the numbers don't line up and the magic smoke comes out....

When I wire something like this, I always look under the covers to see exactly what's
going where and what terminal goes to what. That way there's less chance for
a smoke emitting motor!

Hi There,

Absolutely! That's why I want specifics on the switch and the motor and make a diagram
specific for the application.

Good Luck!
