THERMAL EFFECTS IN THE END-WINDING REGION OF ELECTRICAL MACHINES

Thermal Effects in the End-Winding Region of Electrical Machines

The main heat transfer mechanism in the end-winding region of AMINO 1 FRUIT PUNCH electrical machines is convection.In order to increase the air motion, the rotor is equipped with a series of blades.Their geometry is reflected in the fanning factor, i.e., the ratio between the rotor peripheral speed and air velocity.An accurate calculation procedur

Effect of rf driving frequency on peripheral high energy electrons in a magnetically expanding plasma reactor

Two operational rf driving frequencies of 2 and 13.56 MHz are employed in a 14-cm-diameter radio frequency (rf) plasma source under an expanding magnetic field.The changes in the radial profiles of the ion saturation current and the electron temperature are observed in the magnetically expanding plasma when changing the driving frequency.Peripheral

Rapid experimental evolution of pesticide resistance in C. elegans entails no costs and affects the mating system.

Pesticide resistance is a major concern in natural populations and a model trait to study adaptation.Despite the importance of this trait, the dynamics of its evolution and of its ecological consequences remain largely unstudied.To fill this gap, we performed experimental evolution with replicated populations of Caenorhabditis elegans exposed to th

Isolated tuberculoma involving multiple paranasal sinuses with aggressive features in an immunocompetent individual masquerading as a malignant neoplasm: A rarity unveiled with review of literature

Isolated primary tuberculoma Seat Pad of the paranasal sinuses is an exceedingly rare form of extra-pulmonary tuberculosis (EPTB), particularly in immunocompetent individuals.Its presentation is often atypical, mimicking aggressive neoplasms due to features such as local bone destruction, which complicates diagnosis and may lead to unnecessary inva
