In rotating machinery fault diagnosis, the accurate rotational speed is essential for
interpretating the repeating fault-induced characteristics. However, installation of extra …

It is well known that rotor speed estimation assumes a paramount importance for the correct
diagnosis of bearings, air-gap eccentricities, or rotor bar defects. In this paper, a new …

Multiphase machines have recently been promoted as a viable alternative to traditional
three-phase machines. Most experts are looking for strategies to estimate the rotation speed …
