Understanding and accepting basic laws in electric machinery; according to this knowledge students will be able to describe and recognize some important problems in many engineering fields: mechanical engineering, bio-medicine, food processing industry, and power engineering. The students will meet during the course different types of electric machines.

Upon successful completion of this course, students should be able to: 1) adequately recognize, mathematically describe and understand the most important types of electrical machinery and processes in them; 2) adequate mathematical express and quantify different physical quantities that describe the operation of electrical machines; 3) recognize the need for the application of appropriate electrical machine to the requirements of real engineering problems; define the basic data required to communicate with other professions; 4) recognize on the basis of the acquired knowledge the actual existing electrical drives and perform elementary diagnostics of possible failures of electrical machines. Checking outcomes listed under items 1) and 2) is done via computational tests and exam, as well as via student answers to the questions. Checking outcomes cited under 3) and 4) is based on individual problems addressed to each student to be solved.

Magnetic circuits: Intro,basic components, permeability and hysteresis. Transformers: power transformers, autotransformers, measuring transformers; basic equations, measurements, connections. Electro- mechanical systems; energy conversion principles; force and torque equations. Dc Machines: motors and generators; basic equations, moment characteristics, efficiency. Induction motors (3 phase): principles and equations; construction; implementation. Synchronous machines: types, construction, equations, principle of operation, implementation. Single phase induction motors : specifics in construction and operation Step motors: construction and principles of work; implementation. Control of electric machinery: classical and modern control principles(electronic, frequency, PLC application etc)

Practical lessons include: 1) exercises on the blackboard (numerical examples and problems in general numbers) and 2) labs. Practical classes follow the curriculum of lectures, particularly transformers, polyphase induction motors, motors and direct current generators and a combination of electromechanical coupling. The making of homework is scheduled. Laboratory exercises are: 1) Measurement power of three-phase motors, 2) Demonstration of a three-phase synchronous generator, 3) Operation of three-phase asynchronous motors: basic quantities measurement, change the direction of rotation; 4) DC motor, regulation, demonstration of work.
