On the High Speed Capacity of Bearingless Drives

  title={On the High Speed Capacity of Bearingless Drives},
  author={Hubert Mitterhofer and Wolfgang Gruber and Wolfgang Amrhein},
  journal={IEEE Transactions on Industrial Electronics},
With soaring raw material costs, the need for smaller drives running at higher speeds is ever increasing. In parallel, magnetic bearings and bearingless drives have outgrown the purely academic level and are the state of the art solution for several industrial processes. All the bearingless drives in industry and most of them in academic research run at relatively low speeds of up to 15 000 r/min. Thus, the suitability for high speed operation remained unclear. Along with a brief introduction… CONTINUE READING
