I'd also throw this out their for comment:
In my observations, there are 3 types of motor overloads in the consumer appliance world:
1) solder pot
2) circuit breaker
3) none (thermal failure of the motor windings, bearings or connections)

Both 1) and 2) will fully remove power from the motor until reset (if they work correctly). and shouldnt *normally* cause a 'slow run' condition.

Its easy to reset circuit breakers, solder pots are only reset by giving the motor 30+ seconds to cool down and then trying to restart it.

3) will just burn the motor until it fails completely. While this is isnt really overload protection, its cheaper and if the motor is really low HP, the risk of injury is relatively low.

In the old days, solder pots and circuit breakers would fail internally....giving you all kinds of mixed signals.


I'm interested to see what I'm missing here.
