takoda Report post Posted November 21 Can anyone help me find the correct servo motor compatible with this machine? Found this Pfaff walking foot machine for sale. It has a clutch motor and I would want to switch it to a servo motor as I have with past machines for preference. The seller at the shop doesn't think a servo motor will be powerful enough (says because its a cylinder and not a flatbed), but I don't see how that would be true. I am currently living in Italy so thinking maybe they don't have as much access or know as much about newer servo motors now maybe? The shop owner said if I buy my own servo first that they can install it for me then as long as it fits with the current mounting underneath the table. Thanks!

canvassewing Report post Posted November 21 Hi, I've got a machine like yours but a later model (cream-colored). It's driven by a servo motor from Global at 750 Watt. As a belt I have chosen a 8 mm Polyurethane (green) like this one: https://www.ebelting.com/index.php?main_page=product_info&cPath=1_3&products_id=135&zenid=5a0b06vqsrcbknlgn2v0f46f47 This arrangement works beautyfully!

That is a very pretty table but seems impractical to me with limited usability for a cylinder arm machine more of a show piece. The drop leave end is nice space saving touch. I think when you are sat at the machine you will find that you are going to have to put one leg outside the left side table leg which probably is not going to be a comfortable sitting / sewing position. Also that beautiful hardwood swivel is going to be real pain in the butt, literally. The question I think is would this table arrangement work for the items you want to sew? If you plan on doing bag type work a cylinder arm mounted on a flat table like this one will not give the freedom as a "U" shaped or a table that mounts the machine so the cylinder arm overhangs the end of the table which gives clearance basically to the floor. From the photo of the motor it appears to have the standard triangle mounting arrangement as all motors, clutch or servo. 1 hour ago, takoda said: The seller at the shop doesn't think a servo motor will be powerful enough (says because its a cylinder and not a flatbed), but I don't see how that would be true. A servo will give you better speed control that is much more quiet then a clutch, cheaper to operator as the motor only runs when you press the "go" pedal and provide better bottom end torque. I would suggest finding either a brushed servo motor or brushless servo motor. Like @canvassewing has suggest a 750 watt would probably work quite nicely. If you choose a brushless servo motor the more internal coils it has the better the motor. A couple of questions: i) What do you want to sew?? Fabric, Leather ii) What size of thread do want to use?? iii) Which model is this PFAFF machine?? iv) What are they asking for it?? You maybe better off buying a clone with a proper industrial table setup. kgg Quote Share this post Link to post Share on other sites
Northmount Report post Posted November 21 @takoda Moved your post to leather sewing machines. This is a great area to research machines and servos. Lots of experience gathered here. Quote Share this post Link to post Share on other sites
dikman Report post Posted November 21 Yep, a beautiful table indeed - but as kgg said it might not be too practical when it comes to using the machine. It looks a bit squeezy for the legs. As to a servo, pretty well any servo should work as the mounting plates are all a standard size. 550w will be more than enough but 750w often don't cost much more. The ones on ebay are pretty generic, the control functions usually being the major difference. You would have to mount the control box on the outside of the table due to the limited space underneath. The table may not be the best choice for this machine/motor setup - but it does look nice! Quote Share this post Link to post Share on other sites
AlZilla Report post Posted November 22 Just for reference, I have a 111w151 and 111w153 each with a 550 watt generic servo. The 53 has a speed reducer (torque multiplier), the 51 does not. The 53 easily punches through whatever leather I stuff under it at slow speed, while the 51 can struggle a bit. I don't know the specifics of your pfaff but I suspect most generic servos and a speed reducer should be adequate for your needs. Quote Share this post Link to post Share on other sites
