Looking for information on how to rewind a motor coil

[Johan de Jong]

Hi, I'm considering to rewind a motor coil to be able to run it on another voltage.
But I have no experience with doing that, so I'm looking for help or advice how to do it (or not to if that is the best advice )

The clock that I want to convert is a Tamura Lumitime that is currently setup for 110V/60Hz. As I live in Europe I would like to convert it to 230V/50Hz.
To convert it I would need to:
- replace all resistors and neon bulbs (some are broken, so I better replace all),
- replace a gear in the motor to adjust it for 50Hz,
- replace or rewind the coil to convert to 230V.
The first two I think I can manage, but the last one I have no experience with.

The motor is made by Nikko. I have seen the same motor in some other clocks, but all are pretty rare, so chances on finding a donor clock look dim.



Any help or tips are much appreciated
Thanks!

Johan, I have never done this, but I have read a lot of posts on FAN, Radio etc transformers and motors changing from 110 to 220V
You will need a wire spool and transformer winding "machine" https://ussolid.com/u-s-solid-manual...Ws8XR_2zeHMZkE (can be found on AliExpress). Buying all these parts, plus experimenting will take a lot of time and effort, how about just getting an analog stepdown transformer? From 220V to 110V https://a.co/d/4a9yoFT
At least till you find a proper way how to rewound and do a calculation.

Thanks Aram!

That tool winder looks like a helpful tool. I also found them on AliExpress and the prices are low but the shipping cost spoils the fun. I have also seen video's of homebuilt versions and that might be a cheap solution and good enough for the one or few times I would use it. I see what I can do.
I'm a bit worried about how well it will work with the wire size I will need. The wire for 110V is already very thin and the one for 230 will only be thinner. This will probably be very fragile.

I did consider a step down transformer, or even a frequency converter, but I would rather like to do the recoiling as I find it an interesting hobby project. Finding a solution and doing the work is part of the fun for me
