Course specification
Course is active from 01.01.2024.. The course aims to provide students with fundamental knowledge in electrical machines and power electronics, specifically for application in mechanical engineering fields. After completing the course, students will be able to understand the basic operating principles and characteristics of different types of electrical machines and power converters. They will also be able to identify and describe the main components of an electric drive. The laws of electromagnetism related to the operation of electrical machines (Ampere's law, Faraday's law, and Lorentz's law).
Types of electrical machines: transformers and electromechanical converters.
Transformers: design fundamentals, the principle of operation, power losses and power balance.
Rotating electromechanical converters: DC machines and AC machines (induction and synchronous machines).
DC machines: construction and principle of operation, mathematical model, mechanical characteristic, speed control methods, power losses and power balance. Static converters as a power actuator for DC machines.
Induction machines: construction and operating principles, three-phase stator winding, cage rotor and wound rotor, rotating magnetic field, equivalent circuit, torque expression, mechanical characteristic, speed control methods, losses and power balance. Static converters as a power actuator for induction machines. Single-phase induction machines.
Synchronous machines: construction and operating principles, three-phase stator winding, construction of the rotor, rotating magnetic field, mechanical characteristic, losses and power balance. Inverter-supplied synchronous machines.
Fundamentals of electric drives. Electric drive systems in industrial applications and electric vehicles. Lectures. Practice classes: numerical (N), laboratory (L), computer (C). Individual consultations. The examination consists of the development and defence of an individual paper and an oral part.
