How the electric motors are sold

Replacement Electric clock movements and motors do not come with the hands or mounting hardware. These are sold as to replace worn units for repair on the existing clocks, so these parts would be used from the old unit.

The antique movement issue

There is a big issue with attempting to replace many antique electric clock movement motors as they are no longer in production. Alot of the very good quality antique units made by New Haven or Seth Thomas are not able to be repaired as the motors and movements are not available any longer. It is a real shame but often enough there is nothing that can be done but go with a battery unit instead.

ST 300 Motor Conversion Note By Customer

My Seth Thomas clock's motor burned out. Seth Thomas "Staunton 2-E" mantel clock with an "A-300" mechanism. As far as I know, they don't make that motor any more. I tried to have a company re-wind the motor, but it was crimped together when it was manufactured and would likely be destroyed in the process of trying to repair it. I then looked up the internet and found this webpage.

I was able to line up two of the three screw holes, but I had to re-route the power cord because the wires from the motor now come out at the top instead of out the lower left as in the original motor did. After a couple of weeks I've found that it keeps good time.

If we do not have your electric Movement

We have the most common electric motors on this webpage. These units are sold as replacement units only and do not come with the hardware or hands. We do not have the hardware or hands to offer unfortunately.

Please see if we have what you’re describing on this webpage. If no luck, then try American Time and Signal at this link. As we generalize and stock the most common clock motors, ATS specializes and carries a wider variety of units.
