Electricity is a secondary energy carrier. The generation and the transformation of it starts from a primary energy source (i.e. nuclear power, petroleum, natural gas, coal, hydropower,...) that will take a mechanical form by a transformation process. This energy is turned over into electricity by means of a generator or alternator; the most powerful machines having a capacity of 1500 MWatt. The energy is thereafter put at the disposal of the users who will create either electrical heat or light or an industrial process or an electric drive. The application of electric drives absorbs two third of the total electricity production and is based on electric motors. Electric motors (AC or DC) are found everywhere and have a key position in the industrial and domestic world (i.e. electric traction on public transport, automatic machines, robots, elevators, automatic washing machines, coffee mills, refrigerators,...). The course starts with the operation of the three phase synchronous machine used as motor or as generator. This part of the course is complementary to the analysis of the induction motor in the course "Power Electronics". Subsequently, the course discusses transport of electric energy and the basic principles of protecting an electric transport high voltage network and its stability are discussed. To a limited extend, the construction and the working of direct current (DC), permanent magnet, reluctance and universal motors are discussed.

The students must have acquired knowledge and understanding in the structure, the operation and the characteristics of electric three phase synchronous machines, for their use as motor and as generator. They must have acquired knowledge and understanding in measuring the machine's characteristics (static short circuit test, no-load test, potier diagram, dynamic short circuit test, impedance measurement, sliptest). They must have acquired knowledge and understanding in the function of the synchronous generator in an electric power network and also about the structure of the latter. They must have knowledge about the procedures to protect a high voltage electric energy transport network.
They must have acquired knowledge about the structure, the operation and the characteristics of DC motors and synchronous motors with permanent magnets.
The students must be able to apply this knowledge and understanding to set up a measurement procedure to determine the characteristics of an existing synchronous machine.
The students must be able to communicate the results of the previous in a written report. They must be able to communicate verbally for a peer audience about intermediate results and about the organization of the measuring procedures.
The students must be able by self learning to acquire knowledge about the structure, the operation, the characteristics and the application of other electric motors and generators.
The final grade is composed based on the following categories:
Other Exam determines 100% of the final mark.
Within the Other Exam category, the following assignments need to be completed:
First exam session and second exam session.
An interview like examination is provided during which the students can use all documentation they feel usefull. The students must make an industrial case study, which has not been discussed during the lectures or the practical sessions, and present their results. A minimum of 24 hours of preparation time is made available
