Learning Outcomes
Competences
  • Students have a basic understanding of the most important topologies of magnetic bearing technology and bearingless motors.
  • They can independently carry out (performance) measurements on (high-speed) motors, design and commission magnetic bearings and bearingless motors.
Skills Knowledge
  • Understand different magnetic bearing or motor topologies (k2) and use them to create theoretical models of a magnetic bearing (k6)
  • Can understand problems with magnetic bearings and take stabilization measures (controls, area limitation) (k2, k3)
  • Can analyze theoretical models and determine suitable PID controller settings (k4)
  • Learns and trains the implementation of controls on real systems and the use of analytical control software (X2C) (k3)
  • Can apply loss distribution methods and analyze partial losses (k4)
  • Can select and apply suitable methods of power loss minimization (k5)
  • Understands the problems resulting from supercritical rotor operation and can apply notch filters to solve problems (k3)
  • Can calculate the radial force and torque from the single-phase behavior of a bearingless motor and generate the resulting current-force matrix T_m or its inverse, the force-current matrix K_m (k6)
