Practical Comparison of Two- and Three-Phase Bearingless Permanent Magnet Slice Motors for Blood Pumps [PDF]
ActuatorsThe majority of bearingless permanent magnet slice motors (BPMSMs) used in commercially available rotary blood pumps use a two-phase configuration, but it is unclear as to whether or not a comparable three-phase configuration would offer a better ...

A Novel Driving Scheme for Three-Phase Bearingless Induction Machine with Split Winding
Energies, 2021 In order to reduce the costs of implementing the radial position control system of a three-phase bearingless machine with split winding, this article proposes a driving method that uses only two phases of the system instead of the three-phase traditional

Modeling and Realization of a Bearingless Flux-Switching Slice Motor
Actuators, 2017 This work introduces a novel bearingless slice motor design: the bearingless flux-switching slice motor. In contrast to state-of-the-art bearingless slice motors, the rotor in this new design does not include any permanent rotor magnets.

Optimization Design of Unequal Amplitude Modulated Poles for the Bearingless PMSM
Energies, 2022 The structural parameters of an equal amplitude modulated magnetic pole is limited by the length of the air-gap. When the modulation ratio or carrier ratio is small, the spacing of permanent magnets is too large, which will lead to a worse cogging effect,
