Mechanical systems are suddenly breaking down in the industry, reducing productivity. This happened due to various faults such as unbalance, bearing, misalignment, etc. Primarily, an unbalanced fault occurs in mechanical systems. This study aims to investigate unbalanced faults in mechanical systems to reduce the sudden stoppage in the industry. This study is carried out on the mechanical system for an unbalanced fault. The factors affecting the unbalanced system frequency and mass are investigated using Signature Analysis (SA) and the Taguchi Method. It is observed that the maximum amplitude of vibration occurs at the running frequency of the system when an unbalanced fault is present. Furthermore, it is observed that frequency dominates the unbalanced system more than the unbalanced mass. This study helps the industrialist and researcher implement SA in the industry to identify the type of fault easily. It also suggests that controlling the running frequency is more important than the unbalanced mass. This study is one of the very few investigations that represent unbalanced fault through SA and the Taguchi method.
