(ET) Another mower motor blows.



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?
