Electric clock motor description

Electric clock motors are sold with no hands or hardware. They are sold as a replacement motor for a worn out or broken electric clock. The most popular is the Hansen electric motor in either bottom or rear time set. These were used often in industrial and commercial applications as well as street clocks. The product description will explain how to get the proper hand shaft length on these units.

As far as all those electric mantle clocks with the wooden case made in the early 1900's, no luck. They are no longer made so we do have some alternate movement ideas. This is described in another section and could save the clock from the town dump.

Electric clock hands

If you need hands it may be necessary to modify some long quartz hands to fit. They can be modified to fit the electric unit by filing the minute hand hole. The electric movement hands are hard to come by and usually not available.

It is pretty easy to modify high torque quartz movement hands to fit. They work good on the Hansen electric clock motors. All that is required is to file the minute hand hole some with a needle file. Make it so it will fit on the hand shaft of the Hansen unit, the hour hand will fit fine.

The obsolete antique electric clock

In the 1920's through the 1950's there were many mechanical clocks that had an electric motor to run them. Unfortunately most of those wonderful electro-mechanical shelf clocks have parts that are no longer available. Some of those units were very impressive, combining the electrical motor with a quality brass movement. This then eliminated the requirement of winding the clock for it to function.

Pending doom to the electric clock

If an obsolete antique motor is needed, all you can do is throw the clock trash usually. It maybe possible to find someone to rebuild the coil if that is the issue. We at clockworks.com do not perform such service however. We found it is often unsuccessful and would need to charge way to much for this to happen. In the end the clock would still be left with a motor that is old and worn. This is found not to be a viable long term solution and ultimately a waist of money.

Alternate units for the obsolete

There are alternate units you may consider if your stuck on keeping the clock case. Options include a new wind up movement or battery operated clock movement instead. These conversions are explained more in detail in another section. Quartz units require the center hole of the clock dial to be 3/8 wide. Drilling the 3/8 wide hole in the clock dial maybe required because many of the electric units have a smaller sized hole. Quartz units have a 5/16 wide post to go through that 3/8 wide dial hole. It is a challenge to convert to a quartz unit, and not always successful. The electric clock movement that is now obsolete can be replaced with a quality mechanical unit instead.

The obsolete antique electric clock - Conclusion

If going with a quartz replacement please know the project can go south. An error in drilling the dial out for example could render the dial useless. The clock dial is unobtainable so the project is ditched. Your left with a wood case with nothing to do. Sad story but it is what it is and you maybe best to just buy a new clock if it gets to that point.

If you really like the clock and want it to function and stay high quality, a mechanical unit is best. The mechanical unit would not require the drilling out of the clock dial. It will mount to the wood case and be a back wind instead of plugging into the wall.

Electric Clock - Mechanical Substitutes

All of the antique clock movements that are electric and have a wood clock case are obsolete. They are no longer available and not worth repairing if you could do it. Parts are not available, the movement is useless and the clock looks like its heading for the dump. Such as shame when you like the clock and it is part of your family history. There is something you can do in this situation. Putting a quality mechanical unit as a substitute in the clock case could save the clock and have it running again. It would be a wind up mechanical unit and it will run 8 days every time its fully wound up. The clock will be functioning again and still have highest quality.

The 8 day wind up Hermle 130-678 or 130-627 can be easily mounted in most tambour style clock cases. These are good substitutes to replace an obsolete electric motorized clock movement. Having a back wind mechanical unit such as one of these, there are no concerns with drilling holes in the clock dial to wind it up. Now lets look at some mechanical substitutes for the obsolete electric clock movements.

The Hermle 130-678 clock movement

The 130-678 unit is a bell strike unit that comes with the bells installed. 130-678 is the easiest unit to adapt to a clock case that contained an obsolete electric clock movement. This unit mounts to the wooden clock case with some wood screws only. You will also need new hands for your new movement, any of the German mechanical clock hands you see at the top of this link

  • The winders are on the back, no dial holes to drill out
  • No chimeblock to mount because the movement comes with bells installed
  • Compact and self contained movement fits into the tightest of places

The Hermle 130-627 clock movement

The 130-627 unit is a bottom 3 hammer strike, so if your current electric movement has three rods below, this will work with it. If you have anything other than this as far as the strike goes, you would need to also get the chime block with the movement. This unit will take chime block style A with 3 rods and most likely 7 inch length on the longest rod. This can be ordered at this link.

The length of the rods does not matter so much, just the longer the rod the deeper the tone. You will also need new hands for your new movement, any of the German mechanical clock hands you see at the top of this link
