Marcus,
I have the Baumuller. After replacing the wiring to the brushes and
soldering it to the brush holders instead of using the tiny
connectors it seems to be working fine. It does overheat if i run it
with heavy loads at high speed for a long time. Unfortunately this
is what i need to do. I do appreciate the quietness. Would it make
sense to add a cooling plate to the motor and make it water cooled?
I am running it close to max speed and am cutting 1/2" maple with a
1/4" good quality carbide upspiral bit and am cutting at 40 inches
per minute. The motor speed controller keeps the speed constant and
all works well until the motor gets hot and starts to loose power.
Then i need to stop and let it cool. I think it failed when i did
not do this and it got slow enough to not cut and broke a cutter.
would the ZME with fan work better and is it possible to get for a
reasonable price? i don't think they are in business anymore.

Hi Spencer
I am not certain of the
motor used on your Emco, but the PM 180v DC 4000rpm is
the same as on the F1 milling machine
intended for working with
steel so lower max spindle rpm of 2000, achieved by
pulleys and belt but with reduction rather than increase
as on the F1 Woodworker.
Original makers were either
KEMO (with ZME 200-278 or without ZME 200-285 external
fan cooling) or BAUMULLER ZME 200-290
The ZME part numbers refer
to original replacement brushes.

Changing to a router type
spindle may be the answer but there will be LOTS more
noise.
