This Offering is for a New PFAFF Sewing Machine Top Stepper Motor ID31.  I do not have access to a PFAFF parts catalog so I can not give the actual model of PFAFF machine this Top Stepper motor fits.  I will list all the information on the unit and answer any inquiries and supply additional photos to serious inquiries.  This stepper motor listed for $149.99 a few years ago.
Stepper Motor information on the label:
Stepper Motor ID31 - step angle 7* (degree symbol) 30'  -  MB00 - 5083  -  9904  112  31808.  (and then stamped across the face) - 245846
This Top Stepper Motor is new and in the original packaging.  I only opened the box and plastic for photos and any identifying marks.  This is only one of several new top and bottom stepper motors, motor control circuit boards, bottom surface plates and many other new parts for various PFAFF machines.  I will be selling all of the parts over the next several days and weeks to come.  All the parts listed came from an existing authorized dealer.  I am not a certified repair service technician or dealer.  All inquiries are welcome.
