Self-Sensing Hysteresis-Type Bearingless Motor
CoRR, 2022 Bearingless motors use a single stator assembly to apply torque and magnetic suspension forces on the rotor, making these machines compact with frictionless operation and thus well suited to high-speed applications. One major challenge that prevents wide usage of bearingless motors is the need for air-gap position sensors, which are typically expensive.

Complexity, Volume 2022, Issue 1, 2022., 2022 In this paper, an intelligent neural network‐based controller is designed and implemented to control the speed of a permanent magnet synchronous motor (PMSM). First, the exact mathematical model of PMSM is presented, and then, by designing a controller, we apply the wind turbine emulation challenges.

International Transactions on Electrical Energy Systems, Volume 2022, Issue 1, 2022., 2022 A novel traction AC motor is proposed by grouping magnets and coils in the stator design with aluminium as substantial for the housing of stator and end ring. The stator back iron is designed with silicon steel. As a result, the magnet can provide more repulsion when revolving the rotor, lowering the input side current.

Design and Analysis of Asymmetric Rotor Pole Type Bearingless Switched Reluctance Motor
CES Transactions on Electrical Machines and Systems, 2022 Bearingless switched reluctance motor (BSRM) not only combines the merits of bearingless motor (BM) and switched reluctance motor (SRM), but also decreases the vibration and acoustic noise of SRM, so it could be a strong candidate for high-speed driving ...

Performance Benchmarking of a Novel Magnet-Free Bearingless Synchronous Reluctance Slice Motor
IEEE Open Journal of the Industrial Electronics Society, 2020 This paper presents a novel bearingless synchronous reluctance slice motor topology that contains no permanent magnets. The rotor with two iron poles and flux barriers is levitated and rotated through a stator winding system with six coils wired as two ...
