Characteristics of a bearingless induction motor
IEEE Transactions on Magnetics, 1991A bearingless induction motor with additional windings in the stator slots is proposed. Additional two-pole windings were wound with the conventional four-pole windings to produce radial magnetic forces. These forces, which control the position of the rotor shaft, are produced when magnetic fluxes from the two-pole windings cause an imbalance in the ...

A Novel Parallel Motor Winding Structure for Bearingless Motors
IEEE Transactions on Magnetics, 2013A novel winding structure without separated suspension winding has been proposed for bearingless motors. The proposed winding structure basically has two parallel paths in three-phase motor windings. One three-phase winding path has a neutral point in general, but another three-phase winding path is connected to a suspension inverter, which injects ...

Design variants of the bearingless segment motor
SPEEDAM 2010, 2010Bearingless drives and magnetic bearings allow the construction of contactless, wearless and lubrication-free rotating systems. Utilizing a permanent magnet excited rotor disc permits the passive stabilization of three degrees of freedom (tilting and axial deflection) by reluctance forces. Hence, using these bearingless slice motors it becomes possible

No load characteristics of a bearingless induction motor
Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting, 2002This study involves a bearingless induction motor constructed with additional two-pole stator windings. These additional windings can be used to produce radial forces on the rotor shaft. The two-pole winding currents were regulated by radial position control loops to maintain the rotor's position near the stator center.
