10.    Course Goals (acquired competencies):  This course is an advanced course on small and special electric machines with special emphasis on their experimental analysis. The student will gain wither and deepened knowledge about their specifications, structural realisation and working principles, as well as their application. The student will be able to perform an analysis on small and special electric machines, as well as their integration in novel automated industrial processes in industry, homes and other commercial premises.

11.    Course Syllabus: Introduction. Classification of small machines. Single phase induction machines: principle of operation, revolving field, two phase systems. Types of single phase induction machines. Equivalent circuits and power flow diagrams of single phase induction machines (SFIM). Capacitor induction motor. Shaded pole induction motor. Small synchronous motors (SSM): operating principles, classification. SSM with permanent magnets. Variable reluctance SSM. Hysteresis SSM. Single phase universal commutator motors with series excitation. Servomotors: operating principles, classification and application. Types of control. DC and induction servomotors. Stepper motors: classification and operating principles. Tachogenerators: classification, operating regimes, errors and application. Selsynes. Linear motors: classification, characteristics, operating regimes. Micro and nano technologies for realisation of electromagnetic and electromechanical systems.
