In the "Electrical Machines & Drives" module, students learn how electrical machines and drives are developed and used. 

The aim of the electrical drive is to convert mechanical kinetic energy into electrical energy (generator) and electrical energy into mechanical energy (motor).

Electric drives are the classic core area of mechatronics. First of all, the electric motor, the power electronics that feed it and the measurement, control and microprocessor technology form the hardware of the drive. This is supplemented by thermal and design concepts. Digital measured value preparation and processing, control algorithms, control procedures and AI methods form the software of the drive. A classic drive therefore consists of mechanical engineering, electrical engineering and computer science, i.e. mechatronics. 

Research and development activities in this area are expanding due to the energy transition and increasingly powerful computer systems and are one of the most important fields of activity for researchers and engineers in society. Most renewable electrical energy is generated by electric drives. Around half of electrical energy is converted into mechanical energy in electrical drives. This means that energy efficiency is the big issue for the future of drive technology.

With the help of new technologies, electric drive systems can now be calculated 50,000 times faster than just a few years ago, making it possible to simulate these systems in real time and link the virtual world with the real world of development thanks to the real-time capability of the methods. New concepts and very complex optimizations are made possible, resulting in highly innovative new products that offer very high efficiency in a wide range of load spectra. The energy transition becomes possible.

The fields of knowledge taught in the core subjects of the programme are explored in greater depth and new areas of knowledge are also covered.

Students understand the physical and logical relationships between electrical machines, power electronics, control engineering, modelling and simulation of drive systems.

Students are able to model and simulate simple drive systems. 

Students communicate and cooperate in groups in order to model, simulate and evaluate a given drive technology task.
