Effective immediately, I'm no longer taking in work until, at the earliest, the Fall of 2022. This is so I can address my back-log and will only make exceptions for prior commercial customers. My back-log is such that this is, at best, a guess and it could be later. I will remove this banner when things change. I do not make any recommendations.

Hammond Clock Motor (Rotor)
My business is rebuilding your original motor, when possible. All of these motors cost $150.00 plus $20.00 priority mail (Canada is $45.00) and has a 2-year warranty, which brings your total cost to $170.00. 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 $150.00 to the total and it to would have to be rebuild, so the time frames would still be the same. I do not know of any substitute. In addition to the picture above, these motors are identified by their 15 tooth brass pinion (gear). Hammond produced clocks from 1928 to 1941. My turnaround is 4 to 6 weeks for motor service, 6 to 8 months if the clock is sent with the motor, or if the movement is overhauled. Please see Postal Telegraph Clock for the cost and Hammond movements I do and don't work on. If a movement overhaul is needed it is $300.00 plus shipping. I no longer offer expedited service. If you want to send in the clock for motor or rotor replacement, please be advised that your costs will increase by $90.00 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 Hammond 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 accept personal checks, 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! If you use a personal check then please allow 10 days before shipping to allow the check to clear.
One thing you can do before you send in the motor is to take a Multimeter or Volt/Ohm meter, these are less than $20.00 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 and see if you get a reading. Just about any reading is a good one and lower the better. But if you get no reading what-so-ever then the motor's coil is dead and you will need a coil as well. I do NOT sell these coils separately but do as part of a motor overhaul they are $125.00 each but do sell # 60 or # 14 Telechron coil for the same $125.00 plus shipping.
Hammond’s were mostly made with a movement that did not have a motor (as pictured directly above) and used a coil to generate an eletro-magnetic field that would drive an internal disk. This is considered a (Time Only) movement and an overhaul on a time only electric is $300.00 plus $30.00 shipping, assuming you only send in the movement. The movement overhaul does NOT include the coil ($125.00), so that would be added to the cost of the overhaul, if needed. If this is what you have and you send it in with the entire clock then it’s the same as above with shipping increasing to $150.00 in order to cover the additional labor and shipping costs ($450.00). My turnaround is 4 to 6 weeks for motor/rotor service, 6 to 8 months if the clock is sent with the motor/rotor, or if the movement is overhauled. If the movement is to be overhauled then add $300.00 extra. The confusion is that the picture above is the back of the clock and Hammond’s with the Hammond motor look identical. It is not until the backing is removed and any movement outer covering removed until we know if it has a motor or not. I can and do service both and if you’re sending the entire clock, then it’s my problem and not yours. You can send a picture of the back and sometimes I can tell if it has a motor or not to firstname.lastname@example.org
Another possibility is that an older Sessions that two electrical "motors" from one power source.
Here the bottom motor can be an electro-magnetically driven rotor, a Sessions motor, a Telechron motor, or a Hammond rotor (pictured). The upper motor usually drives the chimes or strike and is usually an electro-magnetically driven rotor. I have worked on every variation and can service the movement or just the Hammond "motor". I use quotes because Hammond calls it a motor but it is in fact a rotor (semantics).
The picture above is the back of the first movement used by Hammond and I DO NOT work on these but do work on all that were made after that because they contain either a clock motor or a magnetically driven disk. The above was only used in the first production in the late 1920’s and all others have a motor or disk and were make in the 1930’s. Hammond produced clocks from 1928 to 1941. Also this clock will say bichronous, which means that it has an auxiliary system with a mainspring that is suppose to "take over" once the power is off. Some of these have the type of mechanism that has leaf spring limiters to regular the time when the current is on and I do not work on these. If you or a local clock shop can take the back cover off and send a picture of what's underneath, then I can tell you if I work on it or not. The word bichronous can be on the front or back or both. Even with that word, I may still be able to work on it but need that picture to be sure.
If the clock states synchronous anywhere then I can definitely work on it.
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.
Please do not send any money or check with the clock. However, if you are sending a Hammond motor only, prepayment is always welcomed because of the relatively short turn around time. I would like payment by, 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%. The 3% is added to the total bill if you use a credit card. 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 not have to be a member of Pay Pal or Square in order to issue a payment but the 3% will be added to your total bill. All of the added fees are exactly what either service charges me for taking your credit card.
You should realize that a Telechron coil will effectively replace the Hammond coil, if the need should arise, with the same wattage considerations. A # 60 or # 14 Telechron coil work well and I do sell those for $125.00 plus shipping.
