I know very little about what features are on what motors. But I
looked on Amazon and they state that one of the Bosch routers has
"overload protection". I would think that's the same thing.

That could simply be a feed back from the speed control switch. If the
motor bogs down the switch feeds more current to speed the motor back up.
If the motor slows or stalls it coud burn up. This is helpful but not a
guarantee. If the motor draws too much current through the switch it could
burn out the circuitry in the switch and or motor. Better would be to have
an additional themal reset switch which you seldom see on universal motors.


But it's not the motor that is dying, it's the electronic speed
control.

If the motor is laboring too much and drawing too much current the switch
could overheat and fail. Probably better than the motor itself. Or the
switch design could be inferior.
