Balance weight fault detection in compressor using FFT algorithm

This paper is investigating stator current to detected balance weight faults and frequency component base on observations in the amplitude of sideband component between healthy and faulty compare with absolute statics and dynamics center of gravity. This paper apply Motor Current Signature Analysis(MCSA) method using Fast Fourier Transform(FFT) algorithm. And show prime features of difference signal between healthy and faulty compressor. Finally also present the relations between center of gravity and fault amplitude sideband frequency components.
