Insight into the construction, functioning and use of drives, on the basis of electrical actuators, completed with power electronics, sensors and regulations. This course is intended for system-integrating engineers who will have to use these drives in global systems. In the additional part, we will look deeper into advanced types of electrical machines (actuators/generators). Finally, practical aspects connected to the concrete implementation of electrical drives will also be discussed.
Basic concepts of system theory, notions of control theory, basic knowledge of electrical machines.

DC drives: stationary and transient behavior, and construction and setting of control loops (torque, speed, position control)
o Induction Machines
- Scalar control: subsynchronous cascade, U / f control, field weakening
- Derivation and implementation field oriented (FOC) and direct torque control (DTC)
o Synchronous machine types
- Synchronous machines with emphasis on permanent magnet machines with sinusoidal control
- Brushless DC Machine
- Switched-reluctance machine
- Stepper motors
Selection of applications, in accordance with each of the machine types: electric transportation (hybrid and electric vehicles, trains),
electrical energy (variable-speed wind turbines), robotics
o Sensors (e.g. speed)
o Digital DSP system implementation
o Parasitic problems including thermal management, electromagnetic compatibility, power quality, noise and vibration
o Energetic aspects: efficiencies
The exercises and laboratory sessions focus on demonstrating the different drives based on real systems. Students optimize at least one type of drive starting calculations, from simulation to verification in lab.

A) Synchronous machines: types, models, transient and subtransient behavior , short circuit, grid connection, parallel operation, behavior in island and strong networks.
B) Small machines:
The scope of small motors today is extremely broad and includes all areas of our world. They are installed in CD players, cameras, washing machines, heating and cooling appliances, cars etc. Traditionally one makes a distinction between three classes based on power: large, medium and small power. Within these classes it is possible to make a partition based on certain special features or elements of the machines. The upper limit, where one speaks of small machines, is a mechanical power about 1000W. These machines are mainly used in drives for consumer goods. In this series of classes on small machines, the following topics are treated :
Defining the various types of machinery and design for small electrical machines
Rotating field, single- and three-phase motors, auxiliary winding with R / C / L
Permanent magnetic materials, PM motors
Small permanent magnet DC machines
Brushless DC motor
AC synchronous motors (permanent magnet, reluctance)
Switched reluctance motor
C) Efficiency aspects of electrical machines and drives
Understanding and solving problems related to the design and use of electrical machines, maintaining a close link with applications.
Evaluation : Electrical Drives; Advanced Topics in Electrical Machines, including Implementation Aspects (B-KUL-H24A4a)
Theory: oral with written preparation. Exercises: written. Both are open book.
The laboratory sessions are evaluated during the sessions themselves.
This exam consists of two parts, matching both teaching activities of the course, so that students who have one of these as a borrowed course in another programme can take the matching exam.
