The radial and levitation forces, necessary to suspend a double conical permanent magnet synchronous rotor, are generated by superposition of the rotor field and two stator fields with one pole pair difference. Due to the superposition of the fields in the air gap, some force interferences are disturbing the levitated drive.

Five-axis magnetic suspension with two conical air gap bearingless PM synchronous half-motors
International Symposium on Power Electronics Power Electronics, Electrical Drives, Automation and Motion, 2012A novel type of “bearingless” permanent magnet (PM) synchronous motor is presented. The motor consists of two conical air gap bearingless PM half-motors, mounted on a single shaft. Each conical stator houses two separate three-phase distributed AC windings with different magnetic pole pair counts.

Conical shaped air dynamic bearings (CS-ADBs) are presented as the bearings used for spindle motors of hard disk drive. Numerical analysis was achieved for the bearings using Monte Carlo direct simulation (MCDS) as the flow of air dynamic bearing could be seen to be a dilute gas flow. The change of the pressure distribution from the rotational start to

The pole placement control with motion decoupling and integral action, according to the full modal synthesis, is addressed in this paper, to control a 1 kW, 18000 min−1 double conical Bearingless Permanent Magnet Synchronous Motor prototype. An electro-mechanical model of the prototype is derived analytically together with the design of the control ...

Experimental Feasibility Study of Conical Gas Foil Bearings for Oil-Free, High-Speed Motors
Volume 8: Structures and Dynamics — Bearing & Seal Dynamics; Emerging Methods in Engineering Design, Analysis and Additive Manufacturing; Fatigue, Fracture & Life Prediction; Probabilistic Methods; RotordynamicsAbstract The increasing demand for oil-free air compressors in fuel cell systems has led to a growing interest in aerodynamic bearing technology. Gas foil bearings are a type of aerodynamic bearings characterized by a compliant foil structure known to enhance the damping properties of the bearings and increase their robustness with ...

A two degrees of freedom permanent magnet conical motor
2018This thesis focuses on the development of an innovative, electrical machine topology, which is based around a permanent magnet, synchronous machine that comprises a conical shape in order to achieve a two degrees of freedom machine. Such a machine is able to produce the rotational torque while also allowing for controlled movement in the axial ...

Topographical features around the conical intersection (CIX) of a fluorene-based light-driven molecular rotary motor have been examined by means of ab initio molecular orbital calculations. The model molecule is a derivative of 9-(2-phenyl-2-cyclopenten-1-ylidene)-9H-fluorene (PCPF) where PCPF is bridged by a pentamethylene chain between the 2 position
