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.

Transient thermal analysis of the conical rotor motor using LPTN and Finite Volume Method
2015 IEEE Magnetics Conference (INTERMAG), 2015Lumped parameter thermal network (LPTN) is widely used for calculation the temperature rise in electrical machines. In LPTN models, heat transfer process in the motor are abstracted form a thermal point of view and can be described via equivalent circuit diagrams, the thermal capacity is modeled by means of a capacitor, as used for describing electric ...

2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016
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 ...

IEEE Transactions on Magnetics, 1999
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

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 ...

The Journal of Physical Chemistry A, 2013
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
