摘要：

A novel single-drive bearingless motor with high passive stiffness and wide gap factor has been proposed. The single-drive bearingless motor has only one set of three-phase windings. It generates both torque and axial suspension force independently with only one three-phase inverter and one displacement sensor. Therefore, the single-drive bearingless motors have the advantages of low cost and small size. Only axial direction z-axis is actively positioned. The other axes, radial movements x and y, and tilting movements theta(x) and theta(y), are passively stable by repulsive passive magnetic bearings. The stator consists of six C-shaped cores and one set of three-phase windings. A novel V-shaped winding structure is proposed to generate the torque and active axial force simultaneously. In this paper, the winding arrangement is presented. In addition, the mathematical calculation is carried out.
