Syllabus
Prerequisites: It is neccesary to know basis of Electrotechnique and Electrical Machines theory.
Examination methods: Traditional
Course unit contents: Basic concepts of electromechanical energy conversion.
Main electrical machinery: DC motor, induction motor, synchronous machine.
Classification, design criteria, problems. Engines with very high dynamics.
Power electronics: electronic components, static converters, rectifiers uncontrolled and controlled, chopper, inverter, PWM modulation techniques.
Criteria for choosing motors and drives: load characteristics, identification of the mechanical characteristics of the machines most appropriate choice of the type of drive and control.
Sizing criteria, calculating magnetic loss calculations, thermal calculation and thermal network.
Outline of project drive with speed control and position for certain types of electric motor, the block diagram of the system, the choice of the regulator.
Solutions of electric motors and electric converters redundant likely to present a high fault tolerance to temporary or permanent (fault-tolerant).
PRACTICAL ACTIVITY IN LABORATORY: development of low power electromechanical systems (e.g., robots, controlled actuators).
