Synchron Clock Motors that are no longer available.

    My business is rebuilding your original motor, when possible.

I'd first check the following to see if your Synchron motor is still being manufactured. Both the Hansen Corporation & American Time carry some of the Synchron motors. As well as I've even seen some NOS (new old stock) on
I am able to rebuilt most Synchron motors.  All of these motors cost $150.00 plus $15.00 priority mail (Canada is $40.00) and has a 2-year warranty, which brings your total cost to $165.00. I must have the old motor in all cases, otherwise I'd have hunt around in my Synchron "boxes" and I hate hunting. My turn time is around a 3 to 4 weeks in all motor only cases. If you send in the entire clock then the turn around increased to 4 to 6 months. If you do not send in the old motor, then there is a $75.00 charge for using one from my inventory, which will have to be rebuilt. If you want to send in the clock for motor or rotor replacement, please be advised that your costs will increase by $95.00 with everything else staying the same. The increase covers the increase in return shipping and insurance and includes my labor charge of $50.00 for the replacement service.  I can ship at that price for clocks up to 22" long ($260.00 total). Overhaul Synchron clock motor $150.00 Labor and cleaning of movement $50.00 Return shipping and handling $60.00 Total $260.00 The above assumes you ship the entire clock and does not include a warranty on the movement (mechanism) because that may need to be overhauled as well.  Most times the movement does not need to be overhauled but if it did then you're looking at an additional $300.00 for a possible total of $560.00, then the movement would have the same 2-year warranty as the motor. I'll not ship the motor until I received payment.   I ONLY accept money orders, certified checks, or company checks for payment but repeat customers may use personal checks.   Normally shipping takes place one week or so after I receive payment and thanks ! I must have the old motor. If your motor is dead then at least I'll have it to match it to the one I'll use from inventory exactly. Using one from inventory adds $75.00 to the total and it to would have to be rebuild, so the time frames would still be the same. Please be aware that my inventory now consists of used motors and these motors must be heat tested and then rebuild before being shipped. This also means that there is the potential that nothing passes and then I'll not be able to help you. If that happens, then I return your old motor at no charge. So please test the motor's coil for continuity and the motor itself for excess heat, which is explained below.
One thing you can do before you send in the motor is to take a Multimeter or Volt/Ohm meter, these are less than $10.00 at any hardware store, and with no current on the motor, set the meter to Ohms and touch the two leads to the end of the wires or the posts where the wires connect and see if you get a reading. Just about any reading is a good one. But if you get no reading what-so-ever then the motor's coil is dead and I cannot repair that specific motor. You should still send it in because I may have an identical one in inventory that I can rebuild. Using one from my inventory adds $75.00 for a total of $225.00 plus shipping. Even with a dead (open) reading on the Ohm meter, there is still the possibility that I can cannibalize a new Synchron's internal coil and drive motor and incorporate your old gearing. That is a possibility and I have done that in the past but if the internal gear box is worn out see below. This service add $100.00 for a total of $250.00 plus shipping. Please don't assume I have an identical motor in inventory. It is extremely important you test the coil before you send the motor and please contact me before you send a motor with a dead coil. If I do use a motor from inventory, that increases your costs by $75.00. I will clean and lubricate the mechanism, which will help in delivering more power and longevity.
If you get a reading, then plug it in for at least 24 hours and see how hot the motor gets. If you can hold it with your fingers for 10 seconds without being burned then the coil would be good enough to rebuilt the motor around it. If you can't then it's not rebuildable because there are too many shorts in the coil and the motor would not have enough torque to last or perhaps not run at all. If you don't want to test it with current, then I'll be happy to and do that right off when the motor is received, so we know what we're dealing with.
One potential problem with Synchron motors is the internal coil generates so much heat that the electro-magnetic torque delivered to the motor is not sufficient to drive whatever it is suppose to drive. For $465.00 I can replace the internal coil with the coil from a new Synchron motor. The irony here is that the new modern Synchron coils run hot but that is how they were designed and this heat does not affect the torque as it does in the older Synchron's. So if the motor is extremely important I will overhaul the internal gear box and install that into a new Synchron motor where I have remove its gear box. The $465.00 include return shipping (that's the $15.00). If this is a unique motor to a unique situation, then the $465.00 option is the only option that warranties the entire motor. I offer this because sooner or later all old motors that are running hot will eventually and permanently fail.
My turnaround is 4 to 6 weeks for motor/rotor service, 8 to 12 months if the clock is sent with the motor/rotor, or the movement is overhauled and expedited ervice adds $100.00 for rotor only service and doubles the labor on the movement overhaul. Expedited service take about 2 weeks for motor/rotor service, one month if the clock is sent with motor/rotor. For return shipping I use USPS for all shipping. If you want to use another carrier then you will have to arrange everything for shipping, meaning I hand the box to the driver, get a receipt and nothing else.

If, for any reason, I cannot rebuild your motor or I cannot salvage an exact substitute, then I'll return your motor at no charge what-so-ever, unless it was expedited service.
I would like payment by money order, certified check, personal check, business check, or through Pay Pal or Square, which is the only way I take credit cards. I do prefer a check over Pay Pal or Square because Pay Pal and Square take 3%. I only take credit cards if you are in the USA or Canada. The 3% is added to the total bill if you use a credit card. With Pay Pal you can pay me directly using "friends and family" where you absorb all fees and I'm paid the full amount. There would be nothing added amount to the final fill if you absorb all fees. Here you log on to Pay Pal and send me the full amount of my bill, so there is no E-voice coming from me with this method and you will be charged all Pay Pal fees on top of my final bill. With either Pay Pal or Square, I will send an invoice to your E-mail address. Here you are dealing directly with either service and not me. You do have to be a member of Pay Pal in order to issue a payment but you may use Square without any membership or additional Square fees but the 3% will be added to your total bill as with Pay Pal. With Square, I can also take the credit card information which includes the number, expiration date and the last 3 or 4 #'s of the security code from the back of the card BUT that adds 3.5% to the final bill. I'd prefer to avoid this method but it is an option. All of the added fees are exactly what either service charges me for taking your credit card.
