Abstract
A current sensor positioned on a power line monitors current draw associated with an electrical motor driven shaft based device, such as a scroll compressor. Mechanical vibrations in the scroll compressor force stress on the motor shaft of the scroll compressor, directly influencing current draw. By monitoring current draw, vibrations resulting from problems in the compressor, such as a broken mounting bracket, can be detected. A controller receives the current values and indicates if a current value exceeds a threshold current value or if a plurality of current values exceed a threshold value.
