On the contribution of magnetic forces to the overall noise of reciprocating compressors

Independent Component Analysis Applied to Hermetic Reciprocating Compressors to Predict Noise Sources

“…The signals chosen to represent the set of sources represent the pressure variation in the compression chamber, the suction valve displacement, the discharge valve displacement, and the magnetic force of the electric motor. The sources described are obtained from the works of [34] for magnetic force, from [35] for pressure in the compression chamber, and from [7] for discharge and suction valve displacements; it is recommended to consult the aforementioned authors for more details. Next, the theoretical sources used throughout the work are presented in Fig.…”
