    Default Any movement as Synchron A43RA running at 220V, 50Hz?

    When in USA I bought a beautiful wall clock, running at 110V, 60Hz. Brought to Europe, I have of course some problems. The voltage is 220V: ok, just a transformer can solve. But the frequency is 50 Hz. From USA I bought a "high-quality inverter", powered by 12 Vdc, with output 110 Vac and frequency "stable and sinusoidal," says the producer, at 60Hz. But the clock does not keep time, it goes a bit 'forward. The movement is a Synchron A43RA-6-76 0020. In your opinion, can I find (and where) a replacement movement, running at 220Vac 50Hz? Should I just change the movement or the whole assembly? Or should I operate (but do not know how: I do not have the circuit diagram) on the inverter? I would like to see it work well: it's too nice! Thank you for your patience and your suggestions: only here I can find an answer.

    You might post a picture of the motor. Many of these have motors that
    come in 60Hz and 50Hz types.
    Your inverter is not intended to run a synchronous clock. It is intended to
    be used with transformer equipment that would over heat with a square
    wave inverter.

    There should be a motor available in the correct voltage and frequency. Yours was made in 1976

    you either have to find a frequency stable 60Hertz source (which would be quite expensive) or a 50HZ motor.

    The motor is made by Hansen mfg - you could contact them and ask who has purchased a 50HZ version of this motor and purchase them from this firm. As hansen has a large minimum order.

    You can get a suitable voltage and frequency convertor from here:

    I use one of their quartz pulse timers to run a Gents slave clock which works well.
