Hello:
Like many other Unimat lathe owners, I have installed a new 24v / 200W motor with electronic speed control on the U3.
Works a wonder, does not overheat, recovers gracefully from mistakes (stalling)? and is very silent.
So I am now faced with finding something to put the OEM motor to good use, if at all possible.
I understand that there is more than one version of this motor, depending on the manufacturing date on the lathe.
My U3 lathe has serial #80070243, so it is from 07/1980 and close to 43 years old.
Just like the motor, which seems to have the orignal carbon brushes with ~50% still left on them.
The motor's stick-on label has a "Gefeg"* logo and reads:
----
Typ Ug720-2S
220v ~ 50Hz (c/s)
95/65W S3-80% 5000/6000/min
Intermittent duty ON 8min/ OFF 2min
Made in Germany
----
No serial number on it.
*
So the question is: has anyone here repurposed their retired Unimat motor for anything worthwhile?
Obviously, the unavoidable 8m/2m intermittent duty spec limits the alternative uses this motor could eventually have, but I was wondering if it could be used to build something which does not require more than 8' use each time.
eg: running a 100/120mm diamond wheel for the finishing or retouching of HSS tools.
Those are the ones most of us end up using after giving up on brazed carbide and indexable insert tools and must be sharp.
I'd appreciate any insight on this.
Thanks in advance,
JHM
