The switched reluctance machine (SRM) is considered to be ideal for numerous safety-critical applications (in aerospace, automotive, defense, medical, etc.) where it is desirable that the electrical drive systems to be fault tolerant. The phase independence characteristics of the SRM enable it to operate (at lower power and higher torque ripples) also under(More)
The switched reluctance motor (SRM) has inherently high level of fault tolerance. However despite of its high robustness and reliability it can face windings and bearings faults. The faults can cause costly downtimes in industrial environment, or they can bring about more severe consequences in safety critical applications. Therefore the detection of the(More)
The paper deals with thermal analysis of the superconducting single-phase high temperature superconductivity (HTS) traction transformer. The purpose is to investigate a thermal distribution of a heat in a cryogen with liquid nitrogen using a FEM software and program Fluent. The outputs are time varying waveforms of temperature in certain points of the(More)
This paper deals with investigation of geometrical dimension influence of multi-barrier rotor on reluctance synchronous motor (RSM) performances. Power factor, efficiency, developed electromagnetic torque and torque ripple are the main investigated parameters. The influence of number of rotor barriers, width of barriers, width of rotor pole pitch, gap and(More)
This paper deals with the improvement of the switched reluctance motor's fault tolerant control for traction drives. The main purpose is to use a control technique which is able to retain the required speed for various load torques at minimal torque ripple also during one opened phase operation. The paper focuses on the comparative study of the current(More)
The paper deals with the electromagnetic design of Ironless Permanent Magnet Synchronous Linear Motor PMLMS for various geometrical configurations of primary and secondary parts by means of Finite Element method in 2D and 3D. The real prototypes are introduced and the calculated results are compared with measured ones.
SUMMARY Switched reluctance (SR) machine has various desirable features, which comes from its simple construction. They are the wide speed range, high temperature operation and small moment of inertia. But without any precise control technique no from these advantages could be utilised. SR machine in generating mode also starts to be used and its control(More)
This paper presents a Switched Reluctance Motor (SRM) design procedure for an electric car drive system. Determination of geometrical dimensions, calculation of static parameters as well as the losses and efficiency is discussed. A dynamic SRM model is outlined and used to calculate the output characteristics of torque and power as functions of the speed.(More)
Simulations are widely used in the study of both electrical machines and drives. In the literature, several simulation approaches can be found which can be also applied in the study of the switched reluctance motors (SRMs). The on-line SRM simulation tool developed by the authors and presented in this paper proved to be very useful both in checking the(More)
