Step motors are motion control mechanisms that convert digital pulses into mechanical shaft rotation. They provide high precision positioning and repeatability of movement without a closed loop control, which is preferable for industrial applications in which accurate positioning control is needed. In this thesis, design and realization of a step motor driver will be performed using micro-stepping, which is based on controlling the current of each winding of the motor continuously and solves noise and resonance problems as well as providing an increase in accuracy and resolution.

Modeling and Simulation of a Boost DC/AC Inverter fed Induction Motor Drive SÜRGEVİL, TOLGA (2011-09-10) Single-stage three-phase boost dc/ac inverters can provide sinusoidal ac output voltages which arc greater than input dc voltage without needing an intermediate dc voltage boost stage. Such a topology is cost-effective due to reduced switch count and it is suitable for compact design These unique features of this type of inverter makes it a suitable choice in many applications such as uninterruptible power supplies, variable speed ac drives, and some distributed power generation schemes. This paper aims to ...
Analysis and design of a novel reciprocating compressor utilizing a minfas-tar mechanism(s) Ercan, Abdulkadir; Soylu, Reşit; Department of Aerospace Engineering (2021-1-26) Similar to the slider crank mechanism that is utilized in a conventional reciprocating compressor, the MinFaS-TaR (Minimum Friction and Shaking – Translation to any Rotation) mechanism may also be used to convert a rotational motion into a translational motion. In the MinFaS-TaR mechanism, the translational and rotational motions can be related to each other in any desired manner. Furthermore, it has favourable dynamic properties. In this study, the piston motion function, , or the chamber pressure function...
Method for suppresion of G-sensitivity of MEMS gyroscope Azgın, Kıvanç; Akın, Tayfun (EPO, 2017) The invention relates to provide a method for suppression of the g-sensitivity of MEMS gyroscope (1) by keeping the movable sense frame of the gyroscope stationary irrespective to the external accelerations with the aid of closed-loop feedback circuit (2)
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...
Stability of Milling Operations With Asymmetric Cutter Dynamics in Rotating Coordinates Comak, Alptunc; Özşahin, Orkun; Altintas, Yusuf (2016-08-01) High-speed machine tools have parts with both stationary and rotating dynamics. While spindle housing, column, and table have stationary dynamics, rotating parts may have both symmetric (i.e., spindle shaft and tool holder) and asymmetric dynamics (i.e., two-fluted end mill) due to uneven geometry in two principal directions. This paper presents a stability model of dynamic milling operations with combined stationary and rotating dynamics. The stationary modes are superposed to two orthogonal directions in ...
