A bearing failure detection system includes a thermal protector switch
circuit having a wear strip located within an interior of a motor stator.
In response to bearing failure or wear above a predetermined magnitude,
the motor rotor will shift off its axis of rotation and wear away the
wear strip or break the electrically conducting material of the wear
strip and activate the stator thermal protector switch circuit and shut
down the electric motor. The wear strips assist the thermal protector
switch circuit in the identification of a bearing failure and the light
rubbing that results therefrom prior to the generation of an electrical
burning smell that may otherwise occur after a prolonged period of
rubbing.
