Learning outcomes:
After successfully completing this course, students will be able to analyze an electrical machine as a drive or power supply network component and use parameters of its equivalent circuit to calculate operating characteristics. They will know the morphological differences between different machine types and their influence on machine behavior in stationary condition. Students will be able to relate the general equation for torque as a derivative of the magnetic energy stored in the air gap to the equations of torque-speed or torque-angle curves of conventional machine types. They will thus, be able to successfully handle complex topics from the field of electrical machines and drives and be able to apply the required analysis tools later in their career or during the Master´s program.
