Variable speed operation of a wind turbine generator improves its energy capturing capability. Up to the present, the machines employed have been induction machines, conventional synchronous machines or DC machines. The major drawback of these machines is that a complicated arrangement of slip rings or commutators with brushes, and a full-rating power converter are required. Reliability and cos...

Doubly Excited Brushless Reluctance Machine (DEBRM) has gained much attention recently in the area of variable-speed constant-frequency generating systems and adjustable speed drives. Two types of reluctance rotor structure, axially laminated and simple salient rotors, are suggested in the DEBRM development. Due to the unconventional pole number combination of the stator and rotor, performance ...

-The Switched reluctance machine (SRM) can be operated as a motor/generator which is the subject of interest by many researchers in the field of electrical machines for the last few decades. Many research papers have concluded that Switched Reluctance Generator (SRG) has proved to be a valid alternative to the classical generators in many industrial applications especially in the field of wind ...

The paper outlines a method for inclusion of the impact of eddy-currents in the model for dynamic prediction of current waveform and force of a switched reluctance machine. The method is based on the equivalent electric circuit model which accounts for the impacts of magnetic saturation and eddy currents in the magnetic core. A linear tubular switched reluctance machine, which includes solid st...

Electric vehicle seems largely based on electrical machines. Finding the best motor type be important for having more performances and a transport system robustness. In this work, we present an analytical model of synchronous machine with variable reluctances in linear saturated modes. The angular position rotor (θ) phase current (i) will beused as parameters. allow us to determinate its magnet...

In the automotive industry, electromagnetic variable reluctance (VR) sensors have been extensively used to measure engine position and speed through a toothed wheel mounted on the crankshaft. In this work, an application that already uses the VR sensing unit for engine and/or transmission has been chosen to infer, this time, the indirect position of the electric machine in a parallel Hybrid Ele...

Abstract: Wind generation systems require mechanisms that allow optimal adaptation of the generator to varying wind speed and to extract maximum energy from the wind. Robust and affordable high-performance methods are also needed for isolated sites. This paper takes this approach, in which an AC switched reluctance generator is used as a generator with a variable rotor speed. Although the volta...
