Reading of magnetic records by reluctance variation
Proceedings of the IEE - Part B: Radio and Electronic Engineering, 1956The paper describes a method of reading information recorded on a magnetic medium, in which the velocity of the medium can have a wide range of values including zero. Read signals are obtained by varying the reluctance of the reading head. With a head constructed according to this principle 50 binary digits per inch have been read from magnetic tape.

Magnetic equivalent circuit of synchronous reluctance machine
2016 ELEKTRO, 2016Finite element method (FEM) is a powerful tool in analysis of electrical machines however, the computational cost is high depending on the geometry of analyzed machine. In synchronous reluctance machines (SyRM) with transversally laminated rotors, the anisotropy of magnetic circuit is provided by flux barriers which can be of various shapes.

Reluctance Motor Employing Superconducting Magnetic Flux Switches
SAE Technical Paper Series, 1992<div class="htmlview paragraph">Superconducting flux switches controlling the magnetic flux in the poles of a motor will enable the implementation of a reluctance motor using one central single phase winding. A superconducting flux switch consists of a ring of superconducting material surrounding a ferromagnetic pole of the motor.

Novel variable reluctance hybrid magnet memory machines
2017 20th International Conference on Electrical Machines and Systems (ICEMS), 2017This paper proposes a novel variable reluctance hybrid magnet memory machine (VR-HMMM), which is geometrically characterized by doubly salient structure having homopolar hybrid magnets alternatively mounted on the stator poles. The magnetizing coils are wound on the PM excitation teeth to vary the magnetization states of low coercive force (LCF ...

Synchronous reluctance and interior permanent magnet motors
2013 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD), 2013This paper focuses on the key notions about analysis and design of synchronous reluctance and an interior permanent magnet motors. The aim is to highlight not only the advantages of such machines but also some drawbacks of theirs, such as the low power factor and the torque ripple. The strategies to reduce such a drawbacks are also reported.

Magnetic Circuit of a Synchronous Reluctance Motor
Electric Machines & Power Systems, 1999This paper presents a model of the magnetic circuit for an axially laminated synchronous reluctance motor. The basis of the modelling technique is the determination of a value for an equivalent "q-channel" reluctance. This reluctance contains all the effects of paths available to q -axis flux through the rotor body.

Magnetic equivalent circuit modelling of Reluctance Machines
2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER), 2016This paper is devoted to the fast modelling of Switched Reluctance Machines (SRMs) and Synchronous Reluctance Machines (SynRMs) by Magnetic Equivalent Circuit (MEC) approach. For SRMs, a combined MEC-FE model is presented. A table of reluctance as function of flux and rotor position is obtained from a reduced FE model which contains a part of the ...

The study of magnetic polarity detection method for permanent magnet reluctance motor
2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015This paper studies a magnetic polarity detection method for permanent magnet reluctance motor (PRM). Inductance characteristic of PRM is different from that of common interior permanent magnet synchronous motor. The inductance characteristic of PRM is verified by electromagnetic field analysis.

Generalized reluctances in eddy current magnetic circuits
Archiv für Elektrotechnik, 1964The concept of generalized—complex or operational—reluctances is introduced. It is shown that these reluctances simplify considerably the calculation of systems, containing magnetic circuits with eddy currents. Two simple applications are worked out. Some results from a numerical study of the magnetic flux on breaking a telephone relay are given.
