31. Optimizing a servo drive using Field Oriented Control
University essay from Uppsala universitet/SolcellsteknikAbstract : An optimization of a servo system for a satellite antenna system wasperformed. A brushless DC motor with an angle encoder was used, whoseangular velocity had to be controlled with great precision. Specializedhardware was used to implement field oriented control to directlycontrol the torque and magnetic flux of the motor. READ MORE

32. Modelling of electromechanical motors for turret and barrel control in main battle tanks
University essay from KTH/FordonsdynamikAbstract : In this master thesis the dynamics of a modern main battle tank's turret traverse and gun elevation have been modelled. The models of dynamic motion have been coupled to two different types of electric motors, namely a direct-current motor and an induction motor. READ MORE

33. Torque Ripple Analysis and Compensation of Servo Drives for Robot Application
University essay from Lunds universitet/Industriell elektroteknik och automationAbstract : Permanent magnet synchronous motors or PMSMs are commonly used in multiple applications, both in industry and commercial use. These motors have many pros when compared to other electrical machines but do present the issue of torque ripple, especially cogging torque. READ MORE

34. Quantification of Drive Cycles for Evaluating Motor Efficiency
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : Due to the goals made by the European Union as well as the country of Sweden regarding the desired decrease of the ongoing greenhouse gas emissions, electrical alternatives have increased enormously in the industry and the automotive areas in recent years. By going from petrol-powered vehicles to electrical vehicles, the transport sector has the potential to produce zero direct emissions. READ MORE

35. Modelling of air-gap harmonic torques and its impact on vibrations in electric drivetrains : Modelling interaction between electromagnetics and vibration of an electrical machine
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In this report, the effect of external torque injection of a particular phase and frequency was analyzed using an induction motor assembly consisting of a prototype of an induction motor and a flexible mounting arrangement. The eigenfrequencies of the several components that make up the construction of the induction machine assembly are found out both by analytical and FEM methods. READ MORE
