This paper studies the effect of stator winding configuration on the performance of five-phase induction machines under healthy as well as faulty conditions. The study compares two connections, namely, star and pentagon connections. The comparison is conducted using both simulation and experimental results. The steady state model based on symmetrical components theory is introduced for both con...

Abstract This paper proposes a thermal network model for calculating the modular permanent magnet motor’s temperature rise. Analyzing actual heat flow path of motor Joule loss and considering circumferential conduction winding, local three-dimensional winding is constructed. Based on model, parts’ steady dynamic rise calculated verified by FEM. The also applies to motors with short ends complex...

The subject of on-line detection of short winding fault in three-phase induction motors is discussed, and a noninvasive approach, based on the computer-aided monitoring of the stator current Park’s Vector, is introduced. The park's vector representation is obtained using Virtual instrument. The Virtual Instrument is obtained by programming in Labview software. The laboratory tests were conducte...

The article deals with the issues of improving energy efficiency mainline locomotives asynchronous traction motors by determining characteristics drive using a device for measuring magnetic scattering field frontal part stator winding.

In this paper, a novel and simple method is proposed for estimating the stator winding real-time temperature of air-cooled hydrogenerator. Firstly, structure characteristics hydrogenerator are analyzed. Then, data-driven proposed, implementation steps illustrated in detail. Finally, estimated by with different days, which validated test. The result shows that can well predict winding, provides ...

Multiphase winding configurations have gained significant attention in high-performance variable speed drives and wind energy conversion systems (WECS) owing to their myriad advantages. In the available literature, various multiphase layouts been designed aiming at boosting machine performance meet requirements of proposed applications. Ultimately, this paper surveyed state-of-the-art for innov...

Analysis of the behaviour of the Brushless Doubly Fed Machine (BDFM) has received considerable attention in the literature. The BDFM is typified by its complex airgap flux distribution. This paper will build upon performance-prediction work, concentrating on the design and electromagnetic behaviour of the BDFM rotor, considering 2 different sizes of 4/8-pole stator machines and comparing test r...

Brushless DC Motors have a permanent magnet rotor and the stator winding are wound such that the back electromotive force (EMF) is trapezoidal. The motor posses high Torque/weight ratio, operate at very high speed, very compact & electronically controlled. In this paper, we have to use three algorithms ZN, GA & PSO respectively. On the basis of performance of these three techniques, PSO have hi...
