Mains synchronous clock movement
Hello,
My mains synchronous clock (made in woodwork class half a century ago) has stopped working. I think the motor coil has gone open circuit. There is only one place that sells the motor, but unfortunately they are trade only! See https://www.cousinsuk.com/product/ma...ous?code=M7814 Note: this has to fit a panel 11 mm thick, there are other ones I can get for a 5 mm panel: however, the construction of the clock makes these unusable. Perhaps I could have the coil rewound? But there may be other problems with the motor, is it worth the risk? Or could I find a friendly clock repairer who could order for me? Michael |

I'm sure Ed Dinning could re-wind it for you.
Or you could re-wind yourself using thicker wire and power it from a small step-down transformer: http://sound.whsites.net/clocks/ocm.html Quote:
Could you post a pic of the motor you currently have, please? Nick. |

Hello Nick,
For Cousins, when you register with them don't you have to confirm that you are in the trade? Michael PS Sorry Nick, photo coming asap. |

Did CE marking exist half a century ago?

Re: Mains synchronous clock movement
You are right, this is a replacement movement! Must be 20 years old though I can't remember exactly.

Re: Mains synchronous clock movement
We have a Cousins account, we have to place an order most weeks.

Re: Mains synchronous clock movement
CE marking started in 1993 replacing the EU mark.

And presumably you don't have to say exactly what trade you're a member of....... you're a "restorer"- a perfectly good trade!

H S Walsh are another supplier who come recommended:

Re: Mains synchronous clock movement
Can we have a pic. of the clock?

Herald1360: Good point!
Phil: Unfortunately neither the CM310 nor the CM311 is suitable. The CM310 has a maximum panel thickness of 5 mm whereas mine is 11 mm; the CM311 is too big and also has no seconds hand. Thanks anyway! The Cousins one (M7814) is now in stock again so I'll try to order from them. Brigham: Yes, indeed, photo coming this morning. |
Re: Mains synchronous clock movement
Another approach is to rewind the motor to operate on a low voltage and add a transformer. I've previously linked here to a website which gives details, but I can't spot my posting at the moment. It makes sense because the typical coil for operation at 240v is wound with thousands of turns of fine wire, whereas rewinding for, say, 6 volts means fewer turns of thicker wire, much more manageable.

Re: Mains synchronous clock movement
Now that is pretty, and you made this when you were in your crib?

Re: Mains synchronous clock movement
Age 14 I think!
Perhaps it could also do with a set of new hands .... |
Re: Mains synchronous clock movement
That's a lovely piece indeed, with a classic 1930s look to it.
