High power density variable speed traction motor

Koushan, Salar
The purpose of this thesis is to develop, manufacture, and test a new traction induction motor that is capable of meeting the desired characteristics, limits and expectations set by the traction application in which it will be utilized. For achieving this goal, initially the finite element (FE) calculation techniques and model accuracy is verified by modeling a reference test motor in a FE environment and verifying the loss data and performance of the motor with measurement data. After testing and modelling the reference test motor, several guidelines and criteria are defined to further help the design process and to ensure the accuracy of the results obtained. In the next step, an initial FE design is developed based on the desired motor rating, and by following the established design criteria (motor’s magnetic loading, electrical loading, current density, and cooling capacity of the motor). Through iterative analytical modification, initial FE model, is improved and an optimum design is selected. Finally, based on the developed model, the motor is manufactured and is verified through comparing the FE data with the test results. Additionally, manufactured motor is tested to ensure that the motor is capable of providing the required performance


Finite element analysis of cornering characteristics of rotating tires
Erşahin, Mehmet Akif; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2003)
A finite element model is developed to obtain the cornering force characteristics for rotating pneumatic tires which combines accuracy together with substantially reduced computational effort. For cord reinforced rubber sections such as the body plies and breaker belts, continuum elements with orthotropic material properties are used to improve solution times. Drastic reductions in computational effort are then obtained by replacing the continuum elements with truss elements which do not require orientation...
Soft starting of large induction motors at constant current with minimised starting torque pulsations
Zenginobuz, G; Cadirci, I; Ermiş, Muammer; Barlak, C (2000-10-12)
The performance of a voltage-controlled, large induction motor soft starter has been improved, resulting in nearly perfect current and torque profiles. The performance analysis of the soft starter, motor - load combination has been carried out in dynamic state using a hybrid induction machine model which takes account of disconnected, two-phase and three-phase operational modes of the machine. Some simple control strategies have been proposed to keep the current constant at any preset value during starting,...
Shape optimization of wheeled excavator lower chassis
Özbayramoğlu, Erkal; Söylemez, Eres; Department of Mechanical Engineering (2008)
The aim of this study is to perform the shape optimization of the lower chassis of the wheeled excavator. A computer program is designed to generate parametric Finite Element Analysis (FEA) of the structure by using the commercial program, MSC. Marc-Mentat. The model parameters are generated in the Microsoft Excel platform and the analysis data is collected by the Python based computer codes. The previously developed software Smart Designer [5], which performs the shape optimization of an excavator boom by ...

Uz, Canan; Özgen, Gökhan Osman; Ciğeroğlu, Ender; Department of Mechanical Engineering (2013)
Design of a test setup to investigate dynamic characteristics of a vibration isolator has been extensively studied over the years and international standards are regulated to explain the basis of the measurements. In this thesis, design efforts to develop a custom test setup for measuring dynamic stiffness of vibration isolators are presented. The setup is designed to conduct dynamic stiffness measurements for various static preload values and over a certain (target) frequency range. Direct Method has been ...
