Mark from Cathedral Sewing Machines demonstrates the great control features a Jack Servo motor gives on a heavy duty industrial walking foot machine. Easy to adjust and great for control of sewing, especially on leather items.
Great video - thank you! Could you do any more for the other functions? My Jack servo came without instructions…I’ve got it installed fine, but I’ve no idea how to complete the set up !!
When you use the synchronizer (needle positioner) and program for needle down, if you step back in the pedal, it will rise the needle. It's a very useful function. I can control stitch per stitch in the pedal, but I added one extra spring because the pedal of my table is too heavy.
Very good control of the slowest speed... I am trying to find a servomotor to replace the one that comes with my new Pfaff 1245 because the lowest speed that I can get is about 0.5. I mean, if I set a speed of 0.5, even if I feather the pedal, the machine goes flat out to 0.5, and in this video I see that you can go stich by stich if you do not press full the pedal... This Jack servo motor looks really good!!! Thanks for the video! :-)
Thanks for the message. We sell them on our website or you can purchase them on EBay. Just look for Jack 3/4 HP servo motor as that is the one on the machine.
Great video - I have the the same motor and would like to attach a sewing light without having to connect it to the mains separately, is there any way I can plug it into the jack 513a to make it work? Thanks very much for sharing this video 🙏
Hello! What is the major difference between this JK 513C and JK 513A models? Visually only the control block looks different and from the pure looks the JK 513A control block appears mroe solid with a larger radiator etc. Is JK513C a stripped down budget version of JK5`3A?
Thanks for the message. You may need to adjust the size of the belt but if not, you can move the motor slightly to suit your current belt. Let me know if you need any help. Regards, Cathedral Sewing Machines
@@cathedralsewingmachines2145 Thank you for your reply! My concarn is about placing this motor on a Juki overlock machine, there's a table on the manual that specifies which belt to use, depending on the motor and pulley, but I suppose the length doesn't affect anything, is this correct?
They can replace the regular clutch motor of sewing machines. Usually servo comes in two main power options, 550W and 750W. There are some with 400W, 600W and 800W, but less common. I have one Jack servo of 750W in my Pfaff 335G and it handles the job of sewing thick layers of Cordura fabric. If you step back in the pedal, the needle will rise (if programmed for lower position when stop). It's a nice motor for the price you will pay.
Thanks for the info - I have bought a servo motor and replaced the clutch motor - it works fabulously -good slow and fast control! Definitely the way to go! I replaced it straight after buying a new machine so I have a brand new clutch motor packed away for when I am more used to using an industrial machine, if I should ever want to use it.
Once you starting use servo motor in sewing machine, you'll never want to use clutch motor again. You just need a good quality once. I would say that this Jack servo is the best for the price. It is not the great one, but at first, will handle good. If some day you want something better, go with PowerMax, Ho Hsing or Efka, but they cost lot more. Hope you keep this happy!
