Calculation of core losses of a six-phase induction motor with third harmonic current injection
Büyükbaş, Afşin; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004)
The advantages of using a six-phase induction motor for industrial drives, over the conventional three-phase drive can be summarized as improved reliability, reduction on the power ratings for the static converters and harmonic reduction. A technique of injecting third harmonic zero sequence current components in the phase currents to improve the machine torque density was presented recently by another research study. However, to meaninigfully evaluate the performnce of such machines and/or to be able to ma...
Diagenesis of Cudi group formations from Dinçer-1 and south Dinçer 1 wells, se Anatolia Turkey
Kahraman Özkan, Ayşegül; Günal Türkmenoğlu, Asuman; Department of Geological Engineering (2010)
Dinçer-1 (1968) and South Dinçer-1 (1980) exploration wells are located at Şırnak Province of Southeast (SE) Anatolia. South Fields of SE Anatolia have received a significant attention after the completion of subjected wells and numerous studies have been implemented regarding this area. Many theories about the geological generation of these fields were put forward by people who studied this region.Both wells have penetrated the Arabian Plate autochthonous units. The Cudi Group, of this sequence, mainly con...
Development of piezoelectric ceramics for ultrasonic motor applications
Kalem, Volkan; Timuçin, Muharrem; Department of Metallurgical and Materials Engineering (2011)
This study has been carried out to develop and manufacture piezoelectric ceramic materials which are utilized for ultrasonic motor (USM) applications. For this purpose, the effect of compositional modifications on the dielectric and piezoelectric properties of lead zirconate titanate (PZT) based ceramics was investigated. PZT based powders were produced using the mixed oxide method. The base composition was selected as Pb(Zr0.54Ti0.46)O3. The samples in the proximity of morphotrophic phase boundary were dop...
Field oriented control of permanent magnet synchrounous motors using three-level neutral-point-clamped inverter
Meşe, Hüseyin; Ersak, Aydın; Department of Electrical and Electronics Engineering (2012)
In this thesis, field oriented control of permanent magnet synchronous motors using three-level neutral-point-clamped inverter is studied. Permanent magnet synchronous motors are used in high performance drive applications. In this study, the permanent magnet synchronous motor is fed by three-level neutral-point-clamped inverter. For three-level neutral-point-clamped inverter different space vector modulation algorithms, which are reported in literature, are analyzed and compared via computer simulations. T...
The Balkan Wars according to the Pravda newspaper
Şarlak, Levent; Turan, Ömer; Department of European Studies (2012)
This thesis has examined the Bolshevik newspaper, Pravda, which began its broadcasting life in April 1912, for the period of the Balkan Wars from October 1912 to October 1913. The objectives of this study are to present and examine the position towards the Balkan Wars of a political group, which viewed the world and the Ottoman Empire from a different angle than the traditional Russian political position of the time, and would seize the power only five years later in Russia.
