Learning outcomes:
After successfully completing this module, students will be able to analyze the steady and dynamic states of electric machines for various applications and calculate their most significant parameters. Students will be able to properly select an electric machine for a given application and adjust it to the load and source. Students will have extensive knowledge about common machine protection methods.
Knowledge of a range of approaches and processes in various industrial sectors will enable students to independently familiarize themselves with modern systems of engine applications and thus, keep their technical know-how up to date.
