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
