Subject description

Prerequisits:

Inscription in third stage of study. Basic knowledge of electric machines.

Content (Syllabus outline):

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.

Objectives and competences:

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 numerical treated stationary and transient electromagnetic and electromechanical states. Students will gain theoretical knowledge required to understand finite element methods for modeling of magnetic and electric conditions in electrical machines. Also, understanding the optimization methods in the design of electrical 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.

Intended learning outcomes:

Student will in-depth understand the principles of electrical machines operation. Mastered the modelling of modern forms of electric machines using finite element method and their presentation in the form of circuit model. All of this will allow the analysis of stationary and transient electromagnetic and electromechanical conditions. Students will gain ability to critically evaluate obtained results and autonomy in the design of new modern electric machines.

Learning and teaching methods:

Lectures (in the case of a large number of students) and project work.
