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!
