Hey /diy/ My grandma tried to fire up a necchi supernova sewing

Its not the motor. Its the foot pedal...

>using double the designed voltage
why do people do this kind of shit?

>>1034955
Don't use 110 volt stuff on 220 systems dumbshit. Jesus.

Its a motor.

First off, Motor.

Second, don't try to run the motor on a voltage it was not meant to run on.

Third, sewing machines should not sit around unused. All of the grease had turned to a rock and the oil to varnish.

To fix the machine, open it up, remove all the old hard grease. Use some long cotton swabs and alcohol. Once done apply grease to all gears. Next look up the oil points for the machine and oil it with sewing machine oil. Also check your belts, as old ones are often hard and useless. Finally plug the motor into the correct power supply and try again.

Without the motor, does it even turn from hand?
Find out how to set the machine to lower thread spooling. Possibly by pulling out the ring at the far end of the machine a little.

I'm asking because some machines have separate settings to couple/decouple the needle and the lower thread spooler from the motor. Maybe they're just both decoupled at the moment.

Just to get something straight, i didn't ran it at 220, but what i got from my grandma is that she did had run it before at that voltage (Again, without success) and even after using 110 with a voltage transformer nothing more than a buzzing occured when pressing the pedal.

Will try the cleaning, thanks a lot for that advice!
As for the motors: Is it posible that there might be a small tranny in the foot pedal? Or did these machines actually took straight up 110V?

Well, the needle dind't even budge when i cranked the hand wheel, so i'm thinking something in the middle is failing too


Also, apparently, this sewing machine was stored in a very damp deposit, and some guy who knows about these old timers told me that it was most likely that it had soaked in a lot of water from the air itself and that has most likely fucked up the motor

Anyway, will try cleaning and will keep you guys up!
Thanks for all the help!

If the sewing machine doesn't turn by hand than the motor wont have a chance. First fix it so the machine turns by hand. Then check out the motor. Its possible the motor is fine and its just the gummed up sewing machine that is causing it to stall. That said, trying to run a stalled electric motor is a great way to destroy it. Don't run it until you get the machine itself fixed or are able to disconnect from the machine.
