Iii abstract this thesis presents a control system for a high-speed solid-rotor synchronous reluctance flywheel motor/generator the objective of this research is to derive a model for a solid-rotor synchronous reluctance machine and provide a control scheme based on the model which has stable performance at high speed. Constant irrespective of shaft load double winding synchronous reluctance motor (dwsyrm) model presented in this thesis work aimed to have better voltage regulation in the second set of winding and performance improvement the detailed literature survey of synchronous reluctance motor based on the performance. This thesis includes an investigation of the starting capability of a high efficiency syn- chronous motor for direct on-line industrial applications the approach is to use a hybrid rotor concept to achieve the starting properties of an induction motor and the steady state performance of a synchronous reluctance. This thesis is concerned with two aspects of the synchronous reluctance motor the q-axis magnetic circuit modelling and the sensorless rotor position estima- tion the modelling aspect of the research looks at the effect that the axially laminated rotor has on the distribution of flux it seeks to find analytical equa- tions that. Motor fundamentals e-learning course tom genberg bachelor's thesis electrical engineering vaasa 2017 motors that are included are 1-phase induction motors, permanent synchronous motors and synchronous reluctance motors the theory used in the work was collected by studying literature on how electrical.
Some conclusions are drawn about the work done keywords— synchronous reluctance machine, machine model, mtpa machine drive, pi tuning i introduction a reason for the thesis dissertation the ever increasing demand for energy efficient electrical machines resulted in a large amount of new motor designs. All im and synrm motors in this thesis have the same standard stator structure for each size the mtpa control strategy is also used in the measurements finally, all reported measurements in this thesis are summarized and analyzed keywords: synchronous reluctance machine (synrm), torque,. Synchronous reluctance motor (synrm) with transversally laminated anisotropic (tla) rotor equipped with damper winding (dw) for direct online operation is studied in the thesis the stator used in the synrm is the same as in a 30 kw, 3- phase, 4-pole induction motor (im) matlab, simulink software has been used for the.
Abstract— synchronous reluctance machines become more popular nowadays development of power electronics allowed reluctance motors to be used in many drive applications due to increased interest in electric vehicles and high prices of pms, the research on electric drives is mainly focused on reluctance machines. Information on the structure of considered drive system with reluctance motor, principle of operation and mathematical model of the motor, principle of the energy conversion in analysed system and elementary types of supply devices have been presented in initial part of the thesis in context of the large world wide.
Abstract this master thesis focuses on the design of a high efficiency permanent -magnet-assisted synchronous reluctance motor (pmasynrm) intended for pump applications the new motor is designed to replace an existing induction motor (im) in a pump product the basic principles of synrm, and pmasynrm motors. The thesis is dedicated to creating a fast and accurate analytical model of the synchronous reluctance machine motor geometries another approach is through analytical modelling, which requires less time to alter for different geometries however, the accuracy of this method is lower than that of a finite element analysis.
Modern computer aided design techniques [12-15] with improvements in the performance of rotating reluctance motors, other types of reluctance machines have emerged over the years [8-11] though rotating rsm are the bases of investigation in this thesis the reluctance synchronous motor with conventional rotor. Performance of the electric drivetrain, especially the electric motor, in traction applications recent fluctuations in the this thesis addresses the computational and design challenges involved in the rotor design optimization of pm-assisted synchronous reluctance machines for traction applications upon presenting a brief. Materials has increased significantly in recent years, electrical motors without permanent magnets draw more attention, such as induction motors, wound- synchronous motors, switched reluctance motors, and synchronous reluctant motors in this thesis, induction and synchronous reluctant machines are.
