It is well known that slotting harmonics exist in most of the electrical machines. So far, these harmonics are mainly identified using spectral estimation techniques. However, this approach requires long sampling and computation periods. In this study, a novel speed and position estimation method based on identification of rotor slot harmonics (RSH) that does not require any kind of spectral analysis...
It is well known that slotting harmonics exist in most of the electrical machines. These harmonics may supply valuable information for condition monitoring of bearings, windings or rotor bars. Utilization of these harmonics for rotor speed and position estimation is limited mainly due to long sampling periods required by spectral estimation techniques. In this study, a novel speed and position estimation...
Air-gap flux of all electrical machines contains harmonics. Some of these harmonics stem from rotor slotting of the machine. These harmonics can be utilized for control or diagnostic purposes. In the literature, rotor slot harmonics are mostly utilized for condition monitoring. There is also some research utilizing them for rotor speed estimation. However, it is observed that in the existing work...
