The paper deals with the design and analysis of a low voltage high current switched reluctance machine used for small automotive applications. The design procedure is based on a numerical algorithm, validated later in simulations and measurements. The idea of the paper is based on designing a switched reluctance machine (SRM) used for driving a wheel chair(More)
A comparative study of several fault-tolerant electrical drives is presented in this paper. As the application is concerned, the authorspsila attention was oriented towards the vehicle transportation. Thus, the main electrical drives under study are: the induction, the switched reluctance and the permanent magnet synchronous machine, respectively. The(More)
In safety-critical systems, faults can cause life losses, environmental degradation, or significant financial losses. In this paper, a segmental stator switched reluctance machine is proposed for such applications. A short overview of its design is given. Its fault tolerance is investigated by dynamic simulations and laboratory tests. It is demonstrated via(More)
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 use of electrical drives and machines with very high number of phases is not a common topic of researchers, because of the control difficulties and the important number of switches needed to assure the operation in faulty conditions. The advantage of using a high number of legs/phases provides smooth mechanical performances (i.e., reduced torque(More)
Critical electrical machines and drives systems used in diverse fields like aerospace, defense, medical, nuclear power plants, etc. require both special motor and converter topologies. In our days due to the recent technological advances and developments in the area of power electronics and motor control the fault tolerant electrical machine and drive(More)
Electrical machines and drives used in diverse critical fields like advanced factory automation systems, automotive and aerospace applications, military, energy and medical equipment, etc.) require both special motor and converter topologies to achieve high level fault tolerance. In the paper a novel modular fault tolerant switched reluctance machine is(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)
