Or make a 5mm thick adapter plate. And rotate holes 10 degrees. Also very
easy. This is probably what I would do unless the motor pcds are already
fitting to motor frame which is unlikely.

I use 1/16" grinding discs all the time for such. I think I'd arrange to
clamp the shaft not the motor frame so as to
reduce vibration on the bearings. It it amazing what those discs will do
at reasonable speeds.

I've not used wire, but have used spinning brass discs to make deep
compression slots, spinning 200 rpms under

Lots of good ideas, here are some less-preferred options:
Find a way to power the motor on top of your lathe or milling machine
ways, and turn the shaft down.
It is possible to

You can use a cutting blade for a grinder they work awesome. So your not
actually grinding. It's slicing. We go through 100s. It's a 5min job

Quick and easy way is to use a 1mm cutting disc on a angle grinder.
Slightly harder option is put it in a mill,
clamp the shaft and cut 5mm off
Just don't bang on shaft and you will be sweet.
I would definitely not take them apart that's a headache

I just got a great deal on three 750w brushless servos and drives to upgrade my
cnc mill. They have the same face dimensions, but the shafts are 5mm longer
than the old brush servos. There was no clearance between the motor shaft and
ball screw inside the coupler, so I need shorten the 32mm
