one thing to note, I used the neuton
circuit breakers on mine also. figured it would be cheap
protection for the motors.

I've been looking at
replacement deck motors.
I have used the Black
and Decker 36v drives and they are still running (2yr -
1acre).
Another deck has tall
motors and the terminal insulation is failing. I could switch
a couple out with HD fat drives but would like to try newer
drives.
It seems the TORO 20"
model #20360 uses the Ametek CPM-160. About 970watts.
Motor + Fan + base+
blade,washer,nut = $245.87 from E Replacement.
The Neuton CE6 motor setup, Motor
+ Fan + base+ blade,washer,nut = $138.54.
Anybody have
any experience with these mowers?

I'll
check with the guys at work, Ametek-Rotron Lamb
electric, build thousands of PM motors, many of which
are used as starters and sit beside the engine. I'm
sure those guys have some pretty good ideas on which
glues hold PM's in place.

Steve Naugler figured out how to reglue
the magnets, I think. Somebody did, anyway,
you should be able to find it in the mailing
list archives.
Well, had the usual deck motor failure.
This seems to happen every other
year or so with tall thin motors:
Mows fine one weekend.
Start mower next weekend, tractor pulls
huge amount of current. Blade is
stopped.
Blade free-wheels, wiring to motor is
smoked.
Take motor top off, commutator is
burned, and armature is obviously
shorted. Motor destroyed.
Any idea why this happens? The inside of
the motor was dry, no problems,
plenty of brush. It's as if the
laminates just decide to fail and burn
everything up.
Now to buy some more motors, my supply
is low. This never happens to fat
motors, they just have the magnets
deglue and shatter all along the
inside. Once again no reason, is there a
glue that will hold them?
