1. 1. Paddle stirrer to a reverberation chamber

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Andrea Mastrorilli; Josefin Holmgren; [2019]
   Keywords : paddle stirrer; reverberation chamber; control system; encoder; magnetic encoder; paddle-omrörare; modväxlande kammare; styrsystem; sensor; magnetisk sensor;

   Abstract : Halmstad University is currently equipped with an Echo-free chamber to perform EMC testing, but no reverberation chamber. The construction of a paddle stirrer to be utilized in Halmstad University would drastically reduce the time required to perform EMC testing, since reverberation chambers are more efficient than Echo-free chambers for these kind of tests.

3. 2. Simulation of an Electrical Machine : with superconducting magnetic bearings

   University essay from Uppsala universitet/Elektricitetslära

   Author : Mesut Bahceci; [2015]
   Keywords : induction motor; superconducting bearings; air-gap;

   Abstract : This master thesis investigates if there is an induction motor configuration that can be used with a flywheel energy storage system, that uses passve superconducting magnetic bearings (SMBs). The configurations should be able to be designed with induction motor building blocks that are commercially available. READ MORE

4. 3. Active magnetic bearing driver circuit design featuring current measurement integration

   University essay from Uppsala universitet/Elektricitetslära

   Author : Lukas Girlevicius; [2015]
   Keywords : active magnetic bearing; current measurement; integration; current loop signal;

   Abstract : Researchers at Uppsala University are developing a flywheel energy storage device intended to be used in electrical vehicles. Kinetic energy storage technology has potential to make purely electric powertrain both more effective and efficient. READ MORE

5. 4. Simulation of a Self-bearing Cone-shaped Lorentz-type Electrical Machine

   University essay from Elektricitetslära

   Author : Jim Ögren; [2013]
   Keywords : Self-bearing machine; bearingless machine; cone-shaped flywheel; 6 degrees of freedom control;

   Abstract : Self-bearing machines for kinetic energy storage have the advantage of integrating the magnetic bearing in the stator/rotor configuration, which reduces the number of mechanical components needed compared with using separated active magnetic bearings. This master's thesis focus on building a MATLAB/Simulink simulation model for a self-bearing cone-shaped Lorenz-type electrical machine. READ MORE

6. 5. Model Predictive Control for Active Magnetic Bearings

   University essay from Reglerteknik; Tekniska högskolan

   Author : Joachim Lundh; [2012]
   Keywords : active magnetic bearing AMB ; model predictive control MPC ; quadratic programing QP ; real time; parameter scheduling;

   Abstract : This thesis discuss the possibility to position control a rotor levitated with active magnetic bearings. The controller type considered is model predictive control which is an online strategy that solves an optimization problem in every sample, making the model predictive controller computation-intense.
