Electrical Traction

The course will be given in German.

Learning objective:

The students learn

• about the structure and main components of an electric traction system,
• to apply the knowledge acquired in the basic lectures to traction systems,
• design a basic layout for traction drive systems and
• they gain an overview of the “railway” system.

Contents:

The lecture covers the fundamentals of electric drive technology for traction applications. The field covers vehicles from tramways to high-speed trains. An overview of the technological development and the current state of the art is given. The main features of the design of vehicle drive systems from requirements to dimensioning are explained.

• Development of electric traction
• From pantograph to wheel
• Drive system technology with three-phase motors
  • Drive system design
  • Induction machine
  • Synchronous machine
  • Inverter
• Control
  • Control methods
  • Processes
• Aspects of the energy supply for electric railways
  • Contact wire and feeder
  • Battery and fuel cell
  • Diesel generator
• Driving dynamics and chassis
• Unconventional railways and maglev trains

Optionally, this module can be extended by participation in an English-language Journal Club, in which students develop, present and discuss the contents of scientific publications under the mentoring of research engineer.
