    • An integrated self-sensing approach for active magnetic bearings 

      Ranft, E.O.; Van Schoor, G.; Du Rand, C.P. (IEEE, 2011)
      Self-sensing permits active magnetic bearings (AMBs) to consolidate the actuation and sensing functions into a single electromagnetic transducer. Eliminating the position sensing device as well as interfacing reduce potential ...
    • A self-sensing active magnetic bearing based on a direct current measurement approach 

      Niemann, Andries C.; Van Schoor, George; Du Rand, Carel P. (MDPI, 2013)
      Active magnetic bearings (AMBs) have become a key technology in various industrial applications. Self-sensing AMBs provide an integrated sensorless solution for position estimation, consolidating the sensing and actuating ...
    • Self-sensing for electromagnetic actuators. Part 2. Position estimation 

      Ranft, E.O.; Van Schoor, G.; Du Rand, C.P. (Elsevier, 2011)
      The second paper in a two part series presents the position estimation scheme for an 8-pole heteropolar active magnetic bearing (AMB). The integrated self-sensing assembly comprises a nonlinear MIMO parameter estimator ...
