    The importance of in-service training in restructuring sectors
    (ELSEVIER SCIENCE BV, 2010) ORAL, BÜLENT; Oral, Bulent; Saglam, Safak; Uzunboylu, H
    Reduction or abolishment operation of government's intervention to economy, accelerating since the beginning of 1980s, is adopted by many governments as governance policy. This policy, being widely used in manufacturing industry and service sector at the beginning, has been used subsequently in electricity, natural gas, water ... etc industry as natural monopoly. The employee needs to know position at institution organization, individual value and expectations. It is effective on the employee performance. In this context, the employees can take in-service education their institutions and regulatory authorities, which regulate and supervise the sectors. The in-service education plan is supported the program content and process by academic circles. In this study, it is emphasized process and content of scheduled in-service education program.

    Transformation of technical education faculties in Turkey in the process of European Union: Faculty of applied sciences
    (ELSEVIER SCIENCE BV, 2010) ORAL, BÜLENT; Saglam, Safak; Oral, Bulent; Uzunboylu, H
    Countries education systems unavoidably changes to adapt themselves to innovations because of developing technology and globalization. This perspective technical education faculty position is queried which are established with the aim of educate technical teachers for vocational high schools in Turkey. Faculty of applied sciences model can replace with the technical education faculty that has completed its mission. It is possible to educate engineers with the faculty of applied sciences who has qualified, keep up the technology and has the characteristics necessary for the working life. (C) 2010 Elsevier Ltd.

    Investigation on efficiency of in-wheel BLDC motors for different winding structures
    (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2019-06-21) SAĞLAM, ŞAFAK; Cabuk, Ali Sinan; Saglam, Safak; Ustun, Ozgur
    Electric machine windings are the essential elements which affect machine performance and efficiency substantially. Two main criteria are considered during winding design: impact on performance and manufacturing costs. In this study, different winding structure combinations are investigated by implementing in an in-wheel motor structure. The motor is a surface mounted permanent magnet BLDC motor which is intended to use in light electric vehicles. According to the design data, the obtained optimum design is manufactured and tested. Accurately captured test results are compared to the calculated values. The direct drive in-wheel BLDC motor used in this study has the rated values of 2.5 kW output power, 900 min-1 shaft speed and 150 V terminal voltage. A Finite Element Method (FEM) based software is used for the design study, that is called ANSYS Electronics Desktop. Effects of different winding topologies are studied by keeping the motor structure and materials unchanged. The validation of the optimized design is realized by conducting the performance experiments. The study shows that the winding topology has a great importance especially for in-wheel motors.
