A technique to improve the performance of grid-connected induction motors by exploiting an auxiliary winding set is proposed in this paper. This features same distribution main winding, although with a reduced number turns and it fed inverter fraction power comparison rated size motor. As shown paper, through possible machine factor, increasing efficiency conversion system mitigating speed osci...

Induction motors are usually considered as one of the key components in various applications. To maintain the availability of induction motors, it calls for a reliable condition monitoring and prognostics strategy. Among the common induction motor faults, stator winding faults are usually diagnosed with current and voltage signals. However, if the same performance can be achieved, the use of vi...

<p>Condition monitoring and on-line detection have attracted several researchers in order to carry out an efficient diagnosis of machine failures. Therefore, the early stage avoids system breakdown reduce maintenance cost. This paper presents a new diagnosic approach detect broken bars end ring faults for squirrel cage induction based on fast Fourier transform analysis applied signature a...

Single winding self-driven synchronous rectification (SWSDSR) approach is a new driving circuit that overcomes the limitations of the traditional driving schemes, becoming an interesting alternative to supply new electronic loads as microprocessors. Traditional self-driven synchronous rectification (SDSR) technique has shown very good performance to improve efficiency and thermal management in ...

This paper is aimed to determine a general model for simulating the single and two-phase induction machines operation. The objective of this model is to predict motor performance parameters such as torque, and motor speed. The model includes representation of both main and auxiliary winding in stationary reference frame and also the effect of core losses and the saturation of the main flux path...

The transient and dynamic performance analysis of a proposed line-start, three-phase concentrated dual-winding synchronous reluctance motor (cDWSynRM) in comparison with the conventional winding (cSynRM) was presented. Both windings are overlapping windings. cDWSynRM consist main auxiliary capacitive assistance for power factor improvement. modelling motors (SynRM) done direct-phase variables c...

In this paper, an interior permanent magnet (IPM) machine having two sets of windings with different number turns is developed to improve the limited flux-weakening (FW) capability and efficiency, simultaneously. The flux-adjustable range appears be somewhat because maximum inverter voltage high magnetic saturation, which degrades FW capability. To address its restricted capability, a unique wi...
