Hello, I am working on a mill/drill and switching the wiring from 115v to 220v. The motor has four numbered black wires #1-4 plus a red and a gray Comming from inside the motor. Total of six wires. Picture #1. The motor needs to be hooked up in such a way it has forward/stop/reverse. The switch is a rotary switch that is new because the original switch was broken Picture #2.
I have a new 220V capacitor as well to replace the original 115v. The wire plate in the motor shows 115v and 220v installation. The new switch has numbers but no wiring diagram.

Oops….wrong picture number one.

 

Oops….wrong picture number one.

 

If the start and run windings are Identical, usually just a SPDT switch with centre off is required.

 

There may be a connection diagram some place on the motor! And the photo leaves much of the information hidden by glare. And as it is a dual voltage motor that adds to the complexity.
Also. I see a second photo that appears to be a switch with ten terminals. Did any information come with the switch, or is it from amazon, with no info and no customer support?? Does the TS have a meter or a continuity checker to verify the switch functionas..???

Thank you for having a look !! I have attached the plate from motor showing the wiring hook ups for 115/230. On that diagram it shows the hook ups for the black numbered wires 1-4 but does not show what to do with the red and the gray wire, all Comming from inside the motor.

I can figure out a switch to work if I just know what wires to hook up to be able to switch the motor fwd and reverse.

Better

 

It looks to me like the red and grey wires would go to a capacitor. And now the big question: did you have the motor before the switch was broken?? The problem is that the colors do not match. So another quuestion is if that broken switch was even associated with that motor.
Do you have the cover for the junction box?? Would it have enough room for a motor RUN capacitor?
Have you tried starting the motor with it connected for high voltage, feeding 220 volts to 3 and 4 with 1 and 2 connected as shown??
If it starts, then change the connections to tie 2 and 3 instead, and apply 230 volts to1and 4 and see if it spins the other way.
But you may need a capacitor.

 

The problems is

if this is on the motor its not going to be wired to reverse.

Hello and thank you again,
you called it right. The red and gray wires going into the motor come out the side and go to a capacitor.
When I received the drill it was powered by 115V. It had a SAF-RUN interrupt wired in and only would run counter click wise. (I left all of this out for clarity reasons figuring starting from scratch with the 220V wiring.
The green switch box in picture is a cheap new one off Amazon. I am attaching a pictur

Thabk you again for your experience and time. You were right on the money with the red and gray wire, they go into the motor and come out on the side to a capacitor (capacitor was bad). I just purchased the black 220V as a replacement.

I left out the back story to try and keep things more clear. Figured switching over to 220V was all new anyways.
The old switch is a rotary type, I have attached a picture. The green one is a new cheap rotary switch from the internet. I think maybe they use the switch to change the polarity for the motor ? Many connections.

 

OK, now I see that you have left us without the first 15 chapters of the 18 chapter book. If the other switch was wired for reversing, there are those folks available who could easily determined how the reverse worked.
To be more specific, THAT WAS A VERY POOR CHOICE!!!
Those "many connections" would probably have been useful for understanding how to reverse the motor.
So now what you need to do is locate the motor manufacturer and download the circuit drawing for it's reversebal operation.

 

To reverse would be easy you move the capacitor wire from L to N problem is don't look like they have those pulled out where you can do that.

I have to own that, making a poor decision.. Thank you. I don’t believe the motor manufacturer wiring diagram is out there to find so thank you again for your time.
If I am stuck with no wiring for reversing is it possible just to wire it for a normal rotation (non-reversing) ) clockwise.

 

Non-reversing can be as simple as the drawing provided already shows. That is the series (high voltage) connection we see in post #10. Reversing might simply involve exchanging the one set of connections like described in post #9.
Discovering how to do that with the new switch is certainly possible, it may take a bit of effort, though.

 

What I have done often as a last resort is contact the Manuf. in this case, Shen Loung Machinery Ltd.
They seem to be a large reputable Chinese Co, most have a support contact of some sort.
Very seldom has this avenue not payed off.

 

Maybe im wrong but you can't change rotation on a single phase motor if it running off L1 and L2 at 240 volts

?? Why so?
The rotation is whether or not the start winding is connected leading or lagging!

 

I've never tried it line to line but most show line to neutral i work only with 3 phase motors not done any single phase rotation in probably 30 years got love 3 phase

 

Line to line is identical, they are both exactly the same, 1ph
The diagram would only make sense for reversing if the ends of each winding were identified.
The diagram is identical if labeled L1 - L2 .
BTW, you also have the cap in series with run winding, it should be start winding. it would only work on a small PSC motor with identical windings.
