“…A bearing has 8 balls with an approximate diameter d of 12 mm and a contact angle of 0 • . Bearing faults are obtained by simply drilling holes in different parts [24]. In order to study the load influence, the induction machine was operated with various load levels ranging from 0 W to 400 W. The measured quantities for off-line bearing fault detection were the line-currents.…”

“…It is easy to point out in these figures that, depending on the operating speed (and certainly on the bearing itsel1), the SK indicator is not fully reliable. It truly reflects the bearing fault at 14 100 rpm while it varies for 10 000 rpm, for other reasons such as DC bus variation or a circlip fault as depicted in [19 ]. Then, a change is made in the calculation of the indicator.…”
