A three-dimensional bearingless motor for a disk-shaped centrifugal pump

研究的目的是实现一个无轴承盘式电机打算用作离心泵，如植入式人工心脏，化学泵等的数值计算的基础上，提出了一种新的悬浮绕组配置，以尽量减少悬浮力方向的误差。与传统的绕组结构相比，所提出的绕组结构在额定转速下的方向误差、振动和功耗分别显著降低了90%、16%和44%。

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.
