Modern electric machines

Overview of the global development of newer forms of electrical machines. Influence of drive system for selection and design of electric machine. The theoretical basis of modern electric machines: single and poly phase machines, permanent magnet machines, electronically commutated and hybrid machines. Energy and power in the circuit describing electromechanical system. The concept of a comprehensive model of the machine in its own coordinate system, circuit theory of electric machines. Electrical and mechanical equations of the machine and its circuit models. Selection and use of appropriate transformations of variables and models. Valuation methods, models nonlinearities, time and spatial harmonics. Using finite element method for modelling magnetic and electric conditions in electrical machines. Optimization methods in the design of electrical machines. Magnetic materials properties description with artificial intelligence methods. Application of numerical methods to solve the circuit models of electrical machines. The synthesis of acquired knowledge in concrete design of modern electrical machines.

The aim of this course is to gain an in-depth theoretical and functional understanding of the operation of modern electric machines. To qualify the student for independent design of modern electrical machines. Analytical and numericaltreated stationary and transient electromagnetic and electromechanical states. Students will gaintheoretical knowledgerequiredto understandfinite element methodsfor modeling ofmagnetic and electricconditions inelectricalmachines. Also, understandingtheoptimization methodsin the design ofelectrical machines. Ability to critically assess the obtained results. Conquered depth knowledge of the theory of electrical machines will enable the design of new modern electrical machines, their integration into modern drive systems. Further implementation of modern electrical machines into electrical energy conversion systems.
