摘要： A canned motor pump has a bearing wear sensing device comprising a pair of ring elements having opposing surfaces. The outer element is mounted fixed with respect to the stator and the inner element is mounted for rotation with the rotor. The outer, fixed element is coated with polytetrafluoroethylene. An ohmmeter measures the resistance between the elements through the coating. As the motor bearings wear, displacement of the rotating element causes wear of the coating which reduces its thickness and decreases the resistance between the sensing elements through the coating. One conductor of the ohmmeter is connected directly to the outer, fixed element, and the other ohmmeter conductor is connected through the conductive bearings to the rotating element. Thus, the ohmmeter can dynamically measure the motor bearing wear.
