Re: Electronic Goldmine motors

Greetings

I got some of them for a future mill/drill and lathe conversion. Also
plan to use them in a large plotter project.

While it could be used as a tach they have a real quadature encoder.

The encoder disk is marked 1000 but no brand name. The reader is an HP
9002 chip as I recall. Nice Al base plate attached to one end of the
motor to mount the encoder chip. Molded plastic cover over the encoder
disk and electronics.

Encoder disk is mounted by a pressed on coller and a spring type speed
nut. May require some careful work to remove the disk.

The motor is probably a 12-24 volt. Motor case is abt 1.5 inches in
diameter and 3.5 to 4 long with double ended shafts probably 1/4 inch.

Motor has no marking on it but looks like good quality construction.

I have not tested then except to apply 12 VDC to two of them and they
spin.
