Course detail
Cooling of Electric Machines and Equipments
FSI-9ESZ Acad. year: 2027/2028 Both semester
The course extends the view of the technical equipment of very often overlooked part of the overall design, which has a major impact on its reliability and efficiency. This is a cooling design that uses selected chapters from hydromechanics, thermodynamics and heat transfer. The main focus is on methods of cooling design and description of steady state and transient heat transfer. Particular emphasis is placed on the interaction of electrical, mechanical and thermal subsystems describing the behaviuor of an electrical machines or equipment. Particularly, emphasizes the interaction of electrical, mechanical and thermal parts that describes the behavior of electrical machines or device.

Entry knowledge
Mathematics: linear algebra, matrix, function of one or more variables, differential and integral calculus, ordinary differential equations.
Basic knowledge of programming
Rules for evaluation and completion of the course
Exam consists of oral or written test of theoretical knowledge (50 points)and of evaluation of the final project (50 points).
Studies is designed in four lecture blocks and as individual with a successive definition of items in the recommended literature. The individual items are controled during consultations in intervals corresponding to the difficulty of the items.
Aims
The goal is to provide knowledge and experience with design of cooling of electrical machines and devices. The next aim is to provide knowledge that can be used for describing of thermal processes occurring in devicess which encountered in engineering practice.
Students should manage theory of description of hydraulic and thermal systems, which appear in electrical machines and devices. They can build mathematical models and solve them with the use of commercial systems. They will also be able to build a complex model of the interaction between electrical, mechanical and thermal parts. In addition, students get basic knowledge with measuring of temperature and air flow in electrical machines and equipment.
