I am in need of the magnetic ring (aka drum) for a integrated spindle motor.
Original p/n is UTMSI-10AABDZE, which is a kit of three parts. The drum, a sensor and a mounting bracket.
I only need the drum.
Somebody out there probably has been in the opposite situation
and only needed the sensor/reader and still has the drum.
Yaskawa is out of stock and they're kinda pricy.
I erased portions of the encoded data on the smooth 8-track tape-like OD surface
with a magnetic pick-up fishing for a screw.
I think any drum with a similar p/n starting with UTMSI-10AA will work,
as long as the OD (appx 4.495") and ID (82mm/3.230") are the same
