Noise reduction of switched reluctance machine
IEEE International Electric Machines and Drives Conference. IEMDC'99. Proceedings (Cat. No.99EX272), 2003In this paper, the results relative to switched reluctance machine (SRM) acoustic noise are presented. The authors have particularly concentrated on the influence of power supply. Vibrations and radiated acoustic pressure have been reduced thanks to the flux instantaneous variation control, which was applied in limiting the duty cycle variations ...

Dq control of switched reluctance machines
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013A method to control switch reluctance motors (SRM) in the dq rotating frame is proposed in this paper. The torque per phase is represented in this paper as the product of sinusoidal inductance related term and sinusoidal current term in the SRM controller. The SRM controller works with variables similar to that of synchronous machine (SM) controller in

Nonlinear Modelling of Switched Reluctance Machine
2019 International Conference on Signal, Control and Communication (SCC), 2019This paper discusses the non-linear modelling and dynamic performance of the Switched Reluctance Machine including the effect of magnetic nonlinearities, such as the model of inductance variation vs current. This variation is analytically described using Fourier series and the nonlinear variation of its coefficients with current will be expressed by ...

Axial Flux Switched Reluctance Machines
2019Switched reluctance machines (SRM) can fall into three classifications based on the direction of flux through the air gap: radial, transversal, and axial flux. The first axial flux machine was developed in 1821 by British physicist Michael Faraday. He invented a primitive disc motor that was the early form of an electric machine.

A Novel Unidirectional Switched Reluctance Machine
SAE Technical Paper Series, 1993<div class="htmlview paragraph">A novel, two-phase, switched reluctance machine concept is presented. Pole side shaping assures that the machine can develop motoring torque from any static position. Pole face shaping is introduced to control the nature of flux linkages as a function of position, allowing reduction in position-dependent torque ...

Mechanical Construction of Switched Reluctance Machines
2019This chapter describes the components and assembly of switched reluctance motors (SRM). It provides a discussions on SRM design and manufacturing. Assembly considerations with respect to lamination alignment, rotor balance, and shaft alignment are discussed to provide guidance on mechanical design of SRMs.

IEEE Transactions on Magnetics, 2014
Vibration and acoustic noises are viewed as a drawback in switched reluctance machines (SRMs), which prohibit their widespread use in noise sensitive applications. Double-stator SRMs (DSSRMs) can be considered as a solution to this problem by incorporating an improved magnetic configuration, which reduces the radial forces in the machine.

Mathematical models of switched reluctance machine system
IEEE International Digest of Technical Papers on Magnetics Conference, 2003Summary form only given. The authors examine how the mathematical models of switched reluctance machine systems can be based on the integral whole of the reluctance machine, the power converter and the control strategy, as well as on the nonlinear model of the electrical network integrated with a two-dimensional finite element model of the machine.

Switched reluctance machines with simple hoop windings
International Conference on Power Electronics Machines and Drives, 2002Switched reluctance machines are usually constructed with coils wrapped around radial poles. The MMF of these coils causes a magnetic flux to flow radially up the poles, returning circumferentially through rotor and stator core backs. As the pole number is increased then the number of coils rises but, due to decreasing space per coil, the MMF per coil ...
