The design of today's high performance synchronous motors must take into account not only the steady state but also practically inevitable dynamic regimes. In such conditions an accurate predetermination of the parameters and constructive solution by modeling and simulation of the given dynamic operation, becomes a mandatory step. In this aim, in the present paper a novel mathematical model of the high power salient pole synchronous machine (SPSM) is elaborated. We proposed to consider especially the effects of the magnetic saturation and saliency. The qualitative and quantitative results show an important number of valuable information in the design stage of the synchronous machine.

Lettl, Jiri; Kuzmanovic, Dragan; Fligl, Stanislav (2011-09-10)
In this paper, the implementation of the Field Oriented Control and the Direct Torque Control in matrix converter supplied induction motor drives is analysed, and compared with the implementation in drives supplied by the Voltage Source Inverter. The analysis is accompanied by the results of numerical simulations and experimental implementations of these two control methods.
Design of synchronous reluctance machines with a wide speed range
Yılmaz, Yusuf Basri; Bostancı, Emine; Department of Electrical and Electronics Engineering (2021-9-10)
Synchronous reluctance machines (SynRMs) are a good alternative for traction and industrial applications due to their good power density, low cost and high efficiency. However, they suffer from high torque ripple, low power factor and poor high speed performance due to their singly excited nature. To overcome these challenges, rotor geometries are optimized to get a low torque ripple and ferrite magnets are inserted in the flux barriers to get a higher power factor and a better high speed performance. Thi...

Petrus, V.; Pop, A. -C.; Martis, C. S.; Iancu, V.; Gyselinck, J. (2011-09-10)
Due to its doubly salient structure and highly nonlinear behavior, the Switched Reluctance Machine (SRM) operates with very high torque ripple. To overcome these inconveniences different average and instantaneous torque control techniques were developed. This paper presents an instantaneous torque control technique named Direct Torque Control (DTC) implemented on a 4-phase, 8/6, 0.75kW SRM. Simulations results with modified flux observer and with fast torque response are presented and discussed, along with ...
Measurement of brushless dc motor characteristics and parameters and brushless dc motor design
Şahin, İlker; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2010)
The permanent magnet motors have become essential parts of modern motor drives recently because need for high efficiency and accurate dynamic performance arose in the industry. Some of the advantages they possess over other types of electric motors include higher torque density, higher efficiency due to absence of losses caused by field excitation, almost unity power factor, and almost maintenance free construction. With increasing need for specialized PM motors for different purposes and areas, much effort...
Prediction of torque and inductance displacement characteristics of asymmetrically slotted variable-reluctance motors using a simplified model for numerical field solution
Ertan, Hulusi Bülent (1999-09-01)
For prediction of static and dynamic performance of doubly-salient motors, it is essential to know their flux linkage-position-excitation characteristics and also the static torque characteristics. At the design stage determination of these characteristics presents difficulties because of highly nonlinear behavior of the magnetic circuit. It is possible to use numerical field solution of the complete motor to obtain this information. This, however, requires expertise on a professional program and may be exp...
