pott motor rewire.
I have a singer 15-91 sewing machine that I bought from a lady on this board. The bobbin winder had broken in shipping. I found a bobbin winder frame from an old 201-2 and they interchanged. It even came with a wirking motor. The lead wire that goes to the motor on the new frame is brittle. can you rewire these? Where can I get information on these.

PATTIESPEARL,
Here is a link to forum member Rayn or Rain ( can't remember which ) blog where he give very concise and detailed instructions on how to rewire motors, including the potted motors. { http://vssmb.blogspot.com/search/label/rewiring } And then a thread I did not long ago with a few comments about rewiring them. { http://www.quiltingboard.com/vintage...r-t205360.html } They might look complicated, but in reality they are very easy. Just follow the instructions in the blog. Joe |

PATTIESPEARL,
The potted motor from the 201-2 and the 15-91 are identical and interchangeable, but the bobbinwinder is not. The bobbinwinder parts are fairly easy to remove from the old broken 15-91 assembly and put on the 201-2's motor assembly. I have done this a fewl times. Cathy

I did take the frame that I bought that came from the 201-s and installed it onto the 15-91. The bobbin winder works great, am just concerned about the brittle wire ot the motor on that one. In my mind, I should be able to take the motor with the good wire and put it into the frame that I now have on the machine. I have already tried the jb weld twice on the old frame. it sits at such a funny angle that the winder would not work.

i have even thought about slipping a piece of heat shrink tubing over the top of the wire and leaving it like that. the motor works very well.

I agree with Jon on this. When I did mine the two motor wires were devoid of insulation all the way up inside the motor. It was unsafe to even test run.
Joe |
that is what i am afraid of. There should be a way to replace the wire going from the motor to the sewing machine
|
Without disassembling the motor there isn't. Did you read the blog I posted the link to above? It is very detailed, but not overly complicated to rewire these motors.
Joe |
I'm with the crew...replace the wires up to the actual motor. After soldering use shrink to insulate the exposed solder joint. Even though the motor may seem to be operating properly, it may only be working on a few tiny stands of wire which will burn it out and make the wiring overheat...better safe than sorry. Rewiring is a critical part of making these old machines safe to use again...good luck!

Take a close look at the wires to the armature of this motor, and the light, and the cord block. The insulation has crumbled off all the way up inside the the motor, to the light, and to the cord block. If the wires are just cut and spliced outside the motor housing you could have a disaster in the making. The insulation in these old machines tend to either melt or petrify and crumble off. It's rare to find one in really good condition. http://i119.photobucket.com/albums/o...resinmotor.jpg http://i119.photobucket.com/albums/o...attheblock.jpg This is why I posted the two links I posted. There is no short cuts to electrical motor wiring repair. If you do it right you're good to sew, if you do it wrong it could be a shocking experience. Joe |
I will read it well. May even try to put the old motor in it. I did not understand when the man that i bought it from said that it could not be done. My original motor is very good.

Thank you JMiller. I live almost at the end of the world when it comes to buying supplies. I got the last of them by mail day before yesterday. I read and copied to a usb drive, the article by Mr Rains. I have taken the motor apart and totaly rewired it, put in new oil wicks. I have it all back together now and it sews beautifully. I was a little afraid to do this on my own, but my dh has such tremors that he can not do things like this any more.

Congratulations Pattie! I cannot tell you how happy posts like this make me. "Motor re-wiring" sounds intimidating to the non-initiated, but when you take it step-by-step, it's not so bad!

PattiesPearl,
I'm glad you took the chance. Isn't it great when you accomplish something yourself. :D Sewing machine motors are fairly easy. I don't usually do household type electric wiring but sewing machine motors don't bother me a all. Joe |
I have never been afraid to tackle a sewing project or reupholstering project, but motors and things of that nature were my husbands passion and I thought it would be too complicated. afraid that I might have some "leftover" parts. I only had one leftover part and couldn't figure out what it was. found out that it was something extra that my dh had placed in the box with the solder pencil.
