The outline design of a fully superconducting motor for liquid hydrogen pump with a magnesium-diboride (MgB2) superconducting wire is carried out to present various advantages arising from its prospective performances. The squirrel-cage rotor winding composed of superconducting loops with the MgB2 wire enables us to operate the motor not only in a slip mode but also in a synchronous rotation mo...

The paper presents diagnostics of induction motor stator faults. The decision on stator winding condition has been taken using the axial flux and based on artificial neural network with radial basis transfer function. The axial flux has been measured for different configuration of stator winding. On the basis of research it can be concluded that the axial flux can be successfully used in detect...

This paper compares four prototype Synchronous Reluctance Motors (SynRMs) having an identical geometry of iron lamination stacks in the stator and rotor. Two different stator winding layouts are employed: a conventional three-phase star connection and a combined star–delta winding. In addition, two rotors are considered: a conventional rotor without magnets and a rotor with ferrite magnets. The...

This paper presents the novel approach in protection and detection techniques of Alternator stator winding from the earth faults which are simulated between 2% to 10% distance point from the alternator neutral, since the impedence at that distance is very high we can not detect or protect by normal methods. The transient produced is analyzed in discreet Wavelet transforms. The potential of usin...

This paper presents two orthogonal axis models for simulation of three-phase induction motors having asymmetrical windings and inter-turn short circuits on the stator. The first model assumes that each stator phase winding has a different number of turns. To model shorted stator turns, the second model assumes phase as has two windings in series, representing the unaffected portion and the shor...

The article presents an analysis of the winding type influence on the efficiency of an induction motor. The aim of this work is to choose such a type of stator winding that the induction motor will have the best efficiency by employing minimum winding (copper) mass. Three types of stator windings were considered in the analysis: concentric single layer winding, concentric double layer winding a...

this paper presents developing an analytical model for flux switching motors. the motor is a class of variable reluctance motors that has two windings on stator; a field winding and an armature winding. due to saliency of both stator and rotor poles, accurate modeling is difficult which arises from the nonlinear behavior of the machine. this paper presents a simple model which is able to predic...

In this paper the fault detection problem is solved using an alternative methodology based on a fuzzy/Bayesian strategy combining a Bayesian network and the fuzzy set theory. The new important issue in this proposed methodology is to address uncertainties in the input of the Bayesian Network. This contribution is possible since the fuzzy set theory is used as the knowledge representation. To il...
