Description
Electric traction motors and their integration into electrically driven road and rail vehicles are essential elements when it comes to successful development of electromobility into the future. However, the electric motor is at the center of new developments not only in electric mobility, but also in many other industrial applications. Companies that want to survive in the market must produce small, power-dense, efficient, and inexpensive motors and systems. Ever shorter development cycles demand very fast design-related decisions. Sound knowledge of the basic design, mode of operation, and advantages and disadvantages of different types of motors is essential if the correct decisions are to be taken.
On this course you will get an overview of the functionality, strengths, and weaknesses of common types of motor (PMSM, SRM, IM, ESM, GSM, and TFM). Together, we will create a rough design incorporating the main dimensions of the motor and its torque-speed characteristics, which will help you to assess, for example, how large the installation space needs to be for the required motor output and how much material you will need when it comes to production. The course is aimed at design engineers, developers, and decision-makers from the fields of drive technology, mechanical engineering, and mechatronics. Likewise, electrical engineers and motor designers will be able to refresh their knowledge.
