Fault Signature Production for Rolling Element Bearings in Induction Motor

摘要: This paper investigates the faults of ball bearings and their effect on both machine vibration stator current. Bearing are categorized into two main groups according to fault signature produced appear in They single-point defect generalized roughness. Single-point produces one four predictable characteristic frequencies depending which surface bearing contains (inner race, outer balls, cage). While, roughness produce broadband change Experimental results given for healthy when it becomes faulty detect
