Publication Open Access Analysis of In-wheel asynchronous motor with conical geometry for electric vehicle(2018-04-01) AKÜNER, MUSTAFA CANER; DEMİR, UĞUR; DEMİR U., AKÜNER M. C.The purpose of this study is to optimize the package geometry in wheel motors for an electric vehicle. In this context, it is aimed to analyze and design in-wheel asynchronous motor with a conical geometry for an electric vehicle. Thus, an asynchronous motor with a conical geometry and in-wheel asynchronous motor with a radial flux have been evaluated by comparing performance against each other within the package boundaries. An asynchronous motor design for the required performance requirements was realized by using the Ansys RMXprt program. The package analysis for the designed asynchronous motor was performed and the minimum and maximum package sizes for in-wheel asynchronous motor. The motor with conical geometry which is designed as a tapered geometry in 3D according to the minimum and maximum dimensions. In the Ansys Maxwell program, these 3 type motors were analyzed in terms of the rated torque, the rated revolution, the starting torque, the breakdown torque, the power factor, the efficiency and the magnetic flux on the rotor and the stator. It has been seen that every motor has advantages and disadvantages in the study. In this context, an asynchronous motor with a conical geometry may provide optimization for the desired properties.Publication Metadata only Malzeme bilgisi: İmalat yöntem ve teknolojileri(Papatya Yayıncılık, 2018-01-01) AKÜNER, MUSTAFA CANER; YAVUZ H., AKKUŞ N., KIRAL Z., AKÜNER M.

C.Publication Metadata only Design and analysis of radiaxial induction motor(SPRINGER, 2018) AKÜNER, MUSTAFA CANER; Demir, Ugur; Akuner, Mustafa CanerIn this study, design and analysis studies of an asynchronous motor with a tapered geometry for a two-person electric vehicle were carried out. The goal of this study is to analyze change in the taper angle for this asynchronous motor in terms of the power factor, efficiency, starting torque, breakdown torque, and rated torque. First, the vehicle dynamics and the asynchronous motor structure were analyzed. Then, axial, radial, and hybrid (radiaxial) flux electric motor models and the purpose of these models were investigated. Literature studies have shown that there is no work related to angle optimization for a radiaxial flux with a conical geometry hybrid structure for an asynchronous motor. The required motor characteristics for a two-person electric vehicle have been calculated. Then, the package volume for the in-wheel motor was analyzed, and the maximum diameter and length of the asynchronous motor were determined. The minimum diameter of this engine package was also specified considering magnetic limit conditions such as saturation factor for rotor and stator of the asynchronous motor. Nine asynchronous motor models were designed and analyzed considering the maximum and minimum motor diameters to investigate the optimal taper angle of this asynchronous motor. And the results were discussed and evaluated.Publication Open Access Analyzing High Efficiency Asynchronous Motors Using Scalar Control Technique(2018-04-01) AKÜNER, MUSTAFA CANER; H. UZUN;O. AKAR;A DEMİRCİ;M.C. AKUNER;U K TERZİIn industry, more than half of the total electrical energy produced in developed countries is converted into mechanical energy by electric motors. The usage rate of asynchronous motors is estimated to be 90% of all electric motors. For these motors, an improvement in efficiency may result in huge savings. These electric motors which have minimized losses can be improved with speed control drives to be more efficient in terms of energy consumption and performance. In speed control drives of asynchronous motors widely used in industry; scalar, vector control and direct torque control are used.In this study, in a Matlab/Simulink environment, high efficiency and standard asynchronous motors with the same characteristics were driven with scalar control technique and the simulations were compared in detail. From the point of view of both speed control performance and energy saving, it observed that high efficiency motors have more advantages.Publication Open Access Neural network approach for E-motor development(2022-06-30) AKÜNER, MUSTAFA CANER; DEMİR, UĞUR; Pourkarimi M., Demir U., Aküner M. C.In this study, the development of electric motor design optimization methods and algorithms for electric vehicles, which have become widespread as a result of energy policies, is discussed. The rapidly increasing need for micro transportation within the scope of small cities has increased the interest in short-range transportation vehicles such as electric bicycles and electric scooters. Therefore, an electric scooter model is considered and the desired motor requirements are determined by analyzing its dynamic model. Then, IPM topologies are investigated and the appropriate topology is decided. IPM design parameters are dealt with in the ANSYS RMXprt environment, and all design combinations by selecting the appropriate test matrix in Taguchi\"s experiment design method are modeled in ANSYS RMXprt and logged in the appropriate file format together with the obtained results. The motor design models of all experiments are saved as the. png format in the aspect format to be determined. Then, the labeled pictures with the obtained results in the experimental design are trained in MATLAB on a neural network model with appropriate input and output. Thereafter, the trained neural network derives the appropriate motor geometry in terms of the design requirements. The derived motor geometry is converted into a 2D technical drawing format with the help of a package program (Img2CAD) and uploaded to the ANSYS Maxwell environment. To assess the motor performance are performed in ANSYS Maxwell. The proposed methodology shows that the results of parameter estimation and geometry generation in solution space with the trained neural network give sufficient performance.Publication Open Access Otonom robotlar için kablosuz sensör ağı uygulaması(2019-08-28) AKÜNER, MUSTAFA CANER; Aküner M. C.Kablosuz Sensör Ağları(KSA), kablosuz bir ortam vasıtasıyla birbirine bağlanmış yüzlerce veya binlerce sensör düğümünden oluşabilmektedir. Sensör düğümleri; dahili batarya, RF adaptörü, mikrodenetleyici ve sensör birimi ile tümleşik bir yapı oluşturur. Kablosuz sensör ağları nem, sıcaklık, ışık, basınç, toprak bileşimi gibi çevresel koşulları izlemenin yanında; nesne hareketi, gürültü seviyesi, ağırlık, boyut, hareket hızı, yönü ve son konumu gibi fiziksel durumları inceleyebilme özelliklerine de sahiptirler. Bu çalışmada, yukarıda bahsedilen çevresel ve fiziksel koşulları izlemek için öncelikle sensör düğümleriyle donatılmış otonom robotlarda MQTT tabanlı bir KSA tasarımı ve gerçeklenmesi üzerinde çalışılmıştır. Ayrıca tasarımı yapılan KSA için, toplanan sensör verilerini uzaktan izlemek için gömülü bir sistem üzerinde çalışan monitörleme yazılımı da geliştirilmiştir.Publication Open Access Competencies of Teachers' use of Technology in Learning and Teaching Processes(KAUNAS UNIV TECHNOLOGY, 2012-12-12) AKÜNER, MUSTAFA CANER; Meral, M.; Akuner, C.; Temiz, I.This research has been done on how the teachers will use technology in teaching-learning processes. Teachers' use of educational technologies in teaching-learning processes has caused alteration in teaching qualification and teacher role. Technology has enabled students to learn in more different dimensions by removing time-place limitations in teaching and learning. Teachers have not only been the source of information as in traditional education methods, but also advisors, counselors and pathfinders who guide students to information and redirect them at reaching information. Using technology in education can be possible via its integration to teaching-learning processes, so teachers use technology in arranging teaching-learning processes. Utilized technology is selected harmoniously for education purposes and environments. Technology must be such as to supply teaching-learning process, not a basis model, and must be eligible to be integrated into teaching-learning processes.Publication Open Access Neural network and IoT-based test maneuver deployment for 2 DoF vehicle simulator(2023-05-15) DEMİR, UĞUR; AKGÜN, GAZİ; YILDIRIM, ALPER; AKÜNER, MUSTAFA CANER; DEMİRCİ B., DEMİR U., AKGÜN G., YILDIRIM A., AKÜNER M. C., ÖZKAN M.This paper presents the driving scenarios deployment for 2 DoF (Degree of Freedom) vehicle simulator based on IoT (Internet of Things) and Neural Network. The controller structure is chosen as Neural Network-based controller is preferred as the transferring appropriate accelerations in 3 axes in the 2 DoF manipulator evokes a nonlinear problem. Due to the microcontroller used in the vehicle simulator to perform Neural Network calculations has limited processing capacity and speed, IoT-based computing and data transferring are chosen. Firstly, an open-loop measurement is performed to identify the vehicle simulator and to generate the training data for the neural network. Thereafter the acceleration data on the axes and the control signals are logged. Secondly, the neural network training is carried out with the logged data. Finally, the trained neural network was tested with various driving maneuvers. And the measurements are evaluated.Publication Metadata only Eksenel akılı sabit mıknatıslı motorların elektrikli araçlardaki kullanımına ilişkin bir inceleme(2013-06-01) AKÜNER, MUSTAFA CANER; HÜNER E., AKÜNER M.
