IEEE Transactions on Industrial Electronics, 2016 Multiphase (MP) induction machines (IMs) provide important advantages over three-phase (3P) ones. Sensorless speed estimation makes it possible to obtain high-performance control and monitoring without the inconveniences of speed sensors. In 3P IMs, the speed estimation methods based on rotor slot harmonics (RSHs), normally on the principal RSHs (PSHs),

IEEE Transactions on Power Electronics, 2018 Multiphase (i.e., with more than three phases) induction machines (MIMs) are particularly attractive for safety-critical applications, because they are able to operate under open-phase fault. On the other hand, algorithms for sensorless speed estimation are of great interest, since, e.g., they improve reliability and decrease cost and maintenance ...

Primary Resonance Analysis of Permanent Magnet Synchronous Motors Caused by Unbalanced Magnetic Pull
IEEE Access, 2021 The dynamic behaviors of permanent magnetic synchronous motors considering unbalanced magnetic pull have been extensively investigated. However, the harmonics and cogging effects are ignored and the stator and the rotor are assumed to be smooth cylinders.

Induction motor’s rotor slot variation measurement using logistic regression
Automatika, 2022 Rotor slots in induction motor expand due to thermal imbalance and create magnetic stress. Magnetic stress is a force that develops on the laminated surface of the rotor due to the curving or stretching magnetic flux.
