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,

Bearingless Windmill-type Gas Flowmeter
Bulletin of JSME, 1981 A bearingless windmill-type gas flowmeter was developed, and its characteristice are described with both theoretical explanation and experimental results. The windmill is mounted on a float, and the float is on liquid in a cup so that the friction against the rotation of the windmill due to friction of the float to liquid is reduced to be negligible at

Comparative performance analysis of bearingless switched reluctance motor
AIP Advances, 2021 To solve the magnetic field coupling problem in the traditional bearingless permanent-magnet motor, which has magnets on the rotor, we propose two topologies of bearingless switched reluctance motors (BLSRMs) with magnets on the stator yoke. The first is
