Mathematical model of a novel 12/14 conical bearingless switched reluctance motor
Energy Reports, 2022 Aiming at the defect that the traditional bearingless switched reluctance motor cannot control the axial suspension force, so that the rotor cannot achieve five-degree-of-freedom suspension by itself, this study presents an innovative 12/14 conical ...

Research on the Axial Force of Conical-Rotor Permanent Magnet Synchronous Motors with Turbines [PDF]
Energies, 2018 The general method to suppress the axial force of the permanent magnet synchronous motor (PMSM) direct-drive turbine is to increase the number of balance devices, such as balance disks and special bearings, to counteract its influence, but this also ...

Conical frustum gel driven by the Marangoni effect for a motor without a stator
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2021 Abstract The Marangoni effect has inspired the development of diverse applications such as robots, gel motors, and self-propelled droplets. A major challenge for the developed gel motors is the need for stators, which dampen the rotating velocity and reduce the motor lifetime due to frictional forces from the stators.

Thermal analysis of the conical rotor motor using LPTN combined with fluid simulation [PDF]
2015 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD), 2015 The temperature investigation for conical rotor motor is relative important at the design step to insure the safety operation. This paper presents a transient thermal analysis mainly based on the lumped parameter thermal network (LPTN). Because the complex structure of the rotor, the computational fluid dynamics (CFD) method is adapted to simulate the ...
