| Research Abstract |
The research objective is to realize a bearingless disk motor intended for use as centrifugal pumps, such as implantable artificial hearts, chemical pumps, etc. Based on the numerical calculation, a novel suspension winding configuration to minimize an error of the suspension force direction was proposed. In comparison to the conventional winding configuration, the proposed one significantly reduced the direction error, vibration and power consumption at a rated speed by 90%, 16%, and 44%, respectively.
