Objectives

Kenntnisse
  • The students can describe and analyze the electromechanical energy conversion in dc machines as well as in IM and SYM, using their gained knowledge.
  • Starting from mechanical quantities like torque or revolution speed the students can derive and explain the coherences to the electrical quantities, including converters.
  • The knowledge is developped with the following contents
    • Fundamentals of mechanics: staionary and dynamic behavior
    • DC-Drives: Setup and functionality of a dc-motor, converter driven motor, revolution speed or torque control
    • Drives with induction machines: Setup and Functuionality of three-phase converters, pulse-width modulation (space-vector modulation), Converter driven Operation of IM, U/f controls, fielf weakening, basics of torque and revolution speed controls.
    • Drives with synchronous machines: Setup and Functuionality of synchronous machines, especially including permanent magnets. Operation in combination with three-phase converters. Current and torque control, Behavior of servo-drives with converter driven PM-SYm, Functionality of highly dynamic drives.

Acquired Skills
  • The students can apply the aquired skills on controlled drives in practice
  • Students can explain different drives concepts with advantages and disadvantages and can perform drives synthesis
  • The students are aware of the importance of drives technology for automation industry.
  • The aquired skills are developped with the following contents
    • Fundamentals of mechanics: staionary and dynamic behavior
    • DC-Drives: Setup and functionality of a dc-motor, converter driven motor, revolution speed or torque control

Objectives

Operational Competences
  • dc-drive with B2 thyristor controller: characterization of typical coherences
  • dc-drive with B2 thyristor controller: characterization of typical coherences of controller concepts including reverser operation
  • Antrieb mit Schwungradspeicher: Innerhalb des Versuches wird ein Schwungrad über eine Asynchronmaschine mit Schleifringläufer und schaltbaren Widerständen hochgefahren und mit einem Gleichstromgenerator abgebremst. Die Studierenden untersuchen die Zusammenhänge zwischen mechanischen und elektrischen Leistungen sowie die Funktion eines rotierenden Energiespeichers.
  • IM including an PWM converter: principles of PWM operation, for specific operational points (M,n) losses are characterized in machines and converters
  • Technical writing of lab reports
