“…Literatura zientifikoan, hiru faseko 6/4, lau faseko 8/6 eta bost faseko 10/8 konfigurazioak dira ohikoenak (7. irudia); horien artean, 8/6 eta 10/8 konfigurazioak jotzen dira egokien ibilgailu elektriko eta hibridoetarako [20]. Ezaugarri hobetuak dituzten topologia aurreratuak ere aurkeztu dira literatura zientifikoan [21,22]. Ordainetan, azken horien konplexutasuna eta fabrikazio-kostua altuagoak dira.…”

Laburpena:Ibilgailu elektriko eta hibridoetako propultsio-sistemetan erabiltzen diren motor elektrikoen artearen egoera aztertzen du artikulu honek. Horrez gain, makina horiek kontrolatzeko ohikoak diren FOC (Field Oriented Control) eta DTC (Direct Torque Control) kontrol-egiturak azaltzen eta konparatzen dira, eta baita motorraren posizio eta abiadura mekanikoa neurtzen duen sentsorerik gabeko kontrola (sensorless, ingelesez) ere: behatzaileetan oinarritutako estimadoreak, abiadura moderatu eta altuetarako baliagarriak direnak, eta salientzia magnetikoan oinarritutako metodoak, abiadura baxu edota ibilgailua geldi dagoenean ezartzen direnak. Amaitzeko, teknologiak etorkizunean izan ditzakeen erronkak eta joerak azaltzen dira. Hitz-gakoak:Ibilgailu elektrikoa, motor elektrikoak, sentsorerik gabeko kontrola. Abstract:This article provides a state of the art of the electric machine technology used in Electric and Hybrid Electric Vehicle applications. Most common FOC (Field Oriented Control) and the DTC (Direct Torque Control) strategies are explained and compared. Position and speed sensorless control strategies are also detailed: observerbased estimators, suitable for medium/high speed ranges and magnetic saliency based methods, applicable for low speeds and standstill operation. Finally, challenges and future trends of this technology are provided.

“…It shows there is a trade-off between reduced costs of machine, convertor and control which most likely results in an oversized motor. The new configuration for high starting torque switched reluctance motor is introduced in [7]. This configuration allows more space for coil windings in small size motors with a high number of stator and rotor poles.…”

Abstract Switched Reluctance Machine is applied for many industry applications because it has simple structure, high variable speed range. This paper is proposed a novel three phase 6/4 two layer field-assisted Switched Reluctance Generator (SRG). This generator consists of two magnetically dependent stator and rotor sets. The magnetostatic analysis includes mathematical and simulation analysis using Finite Element Method (FEM) is carried out in this study.

Abstract-In this paper, a new hybrid method of obtaining the degrees of freedom for redial airgap length in Switched Reluctance Motor operation under normal and faulty conditions based on magnetostatic analysis is presented. At the beginning, this method goes through the magnetic design of the motor utilizing three dimensional (3-D) Finite Element Method (FEM) in order to consider the end effects as well as axial fringing field effects. The motor parameters, such as torque, flux linkage, flux density versus rotor position are precisely obtained. Then, a Multi Layered Perception Neural Network is designed by considering the nonlinear behavior of the motor parameters obtained under different modes of operation. Using this network and the obtained parameters from FEM, an Objective Function (OF) for torque ripple with the aim of having a minimum mean square error is estimated. In addition, an improved Genetic Algorithm (GA) for the minimization the OF is also presented to determine the motor's operational regions. Finally, the legal intervals for different modes of motor operation are addressed.
