Electrical Machines

Education facts

Code: ELGB19

Instruction is in the form of lectures, exercises, and mandatory laboratory sessions. Magnetic circuits: important properties in non-linear magnetic materials, calculations of magnetic circuits, magnetising losses, and magnetising current. <br> Transformers: step down and step up transformers, law of induction, transformer theorem, idling, load, voltage drop, equivalent scheme, loss, efficiency, structure, materials, coiling, cooling, three-phase connection, rated current data in switching, transformer testing, short circuit impedance, winding connector, parallel connection of three-phase transformers. <br> Direct current machines: construction, theory, separate-, shunt-, and series magnetisation, armature reaction, commutation, loss, efficiency, start, brake, speed rotation control. <br> Asynchronous machines: construction, theory, short circuit- and slip-ring machine, loss, efficiency, start, brake, speed rotation control, single phase operation, generator operation. <br> Synchronous machines: construction, theory, generator and machine operation, over- and under-magnetising, start, phase synchronisation, loss, efficiency.
