The existing instantaneous power analysis and stator current analysis techniques are unable to diagnose bearing surface roughness defects, due the fact that characteristics defect frequency model is not available for the bearing surface roughness defects. Thus, this paper proposes a Park's transformation method which can detect surface roughness defects without requiring information of the characteristic defect frequencies. The theoretical and experimental work conducted shows that the proposed method can detect bearing inner race surface roughness faults without use of any extra hardware. The results on the real hardware implementation confirm the effectiveness of the proposed approach. {\^A}{\copyright} 2015 IEEE.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84971668250&doi=10.1109\%2fICSIPA.2015.7412245&partnerID=40&md5=f9120e805e1b534afa7a2900fc61d2b0}, keywords = {Condition monitoring; Hardware; Image processing; Induction motors; Machine vibrations; Reconfigurable hardware; Signal detection; Signal processing; Surface defects, Bearing surfaces; Defect frequency; Hardware implementations; Instantaneous power; Park's transformation; Stator currents, Surface roughness} }
