Main objective of this study is to design a compliant mechanism with high frequency and high mechanical amplification ratio to be used for amplifying the stroke of a piezostack actuator. In this thesis, first of all, related literature is investigated and then alternative conceptual designs are established utilizing the mechanisms found in literature survey. Once best conceptual design is selected, detailed design of this mechanism is done. For detailed design of the compliant mechanism, topology optimization method is used in this study. To design the mechanism, first a design domain is defined and then a finite element model of the design domain is prepared to be used in topology optimization runs. After running the topology optimization model by using TOSCA with ANSYS, results are imported to ANSYS, where final performance of the mechanism design is checked. After finalizing design of the mechanism, it is produced and its performance is tested through experiments

Design of a Piezoelectric Ultrasonic Motor for Micro-Robotic Application
Akın, Tayfun; Başaran, Dilek; Erden, Abdülkadir (null; 2002-09-05)
In a piezoelectric ultrasonic motor, exciting at least two orthogonal mechanical vibration modes of the composite stator using single or orthogonal multiple high frequency AC signals generates a mechanical vibration on the stator surface. The rotor is pressed against the stator's surface and a rotation is produced by frictional interaction between the touching stator and rotor surfaces. Piezoelectric ultrasonic motors, which have superior characteristics like; high torque at low speed, frictional locking at...
Design of a GaN Based Integrated Modular Motor Drive
Uğur, Mesut; Keysan, Ozan (2018-10-25)
In this study, design procedure of an Integrated Modular Motor Drive (IMMD) is presented focusing on high power density. The design is based on a permanent magnet synchronous motor (PMSM) and GaN FETs. Fractional slot concentrated windings are used on the stator. Slot/pole combination and winding configuration is selected based on having low cogging torque and high winding factor. An extended motor drive inverter topology is proposed where 2-level voltage source inverters are connected both in series and pa...
Design and optimization of high torque density generator for direct drive wind turbine applications
Zeinali, Reza; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2016)
In this thesis, it is aimed to design a high torque density generator for a variable speed, direct drive wind turbine application. Such a generator may reduce the size of the turbine tower and the nacelle and may provide cost advantage. For this purpose, various topologies of the permanent magnet machines in the literature are reviewed. Among the reviewed electrical machines, a magnetically geared machine introduced as a concept with high torque density and high power factor is chosen to be evaluated for th...
MODELING OF A CAPACITIVE Sigma-Delta MEMS ACCELEROMETER SYSTEM INCLUDING THE NOISE COMPONENTS AND VERIFICATION WITH TEST RESULTS
Boga, Biter; Ocak, Ilker Ender; Külah, Haluk; Akın, Tayfun (2009-01-29)
This paper presents a detailed SIMULINK model for a conventional capacitive Sigma-Delta accelerometer system consisting of a MEMS accelerometer, closed-loop readout electronics, and signal processing units (e. g. decimation filters). By using this model, it is possible to estimate the performance of the full system, including the effect of individual noise components, operation range, scale factor, etc. The model has been verified through test results using a lateral accelerometer, full-custom designed 2nd-...
An analytical approach for determination of optimal stator/rotor saliency number of a swıtched reluctance motor
Kılınç, Cem Erkan; Bostancı, Emine; Department of Electrical and Electronics Engineering (2020)
The purpose of this study is to seek the optimal stator and rotor saliency number of a switched reluctance motor (SRM) for hybrid electrical vehicle (HEV) applications. For this purpose, first a previously developed SRM analysis software is investigated to identify possible errors in implementation of both the theory and the coding. Performance prediction method is based on the use of normalized force and permeance data produced via numerical field solution, and a polynomial based interpolation is introduce...
