Permanent magnet synchronous motors (PMSM) are known for their type whose magnets located on the rotor surface and this motor type, which is called mounted (SPM), generates torque due to rotor. Based equations, since there only q axis current value of magnetic flux linkage, d kept at 0 maximized controlled, I_d = control technique. However, reluctance generated in interior permanent (IPM) induc...

IR light guides based on crystals and ceramics of the AgBr-AgI system are transparent in mid-infrared range from 2 to 25 μm, which is demand for thermal imaging, laser technology spectroscopy. High photo- radiation resistance makes these materials particularly attractive. For design optical equipment, information needed electrical properties material, most fully characterized by current-voltage...

Three events are presented where high-resolution measurements from the Swarm satellites coincided with excellent F-region ionospheric coverage The Super Dual Auroral Radar Network (SuperDARN). Large-scale convection patterns SuperDARN, together field-aligned-current he Active Magnetosphere and Planetary Response Experiment (AMPERE), provide information on quasi-static dynamics traversed by Swar...

Abstract Benefitted from progress on the large-diameter Ga 2 O 3 wafers and processing techniques, power device technology has witnessed fast advances toward electronics applications. Recently, reports large-area (ampere-class) devices have emerged globally, scope of these works gone well beyond bare-die demonstration into packaging, circuit testing, ruggedness evaluation. These results placed ...

Multiple instability was found on the volt-ampere characteristic of palladium-surface-oxidized indium phosphide structure. The effect is recorded when recording dependence differential conductivity and capacitance applied external voltage. A mechanism for appearance instabilities proposed.

We prove that if φ : R × R → R, d ≥ 2, is a homogeneous function, smooth away from the origin and having nonzero Monge–Ampere determinant away from the origin, then R#{(n,m) ∈ Z × Z : |n|, |m| ≤ CR;R ≤ φ(n,m) ≤ R+ δ} . max{R 2 d+1 , Rδ}. This is a variable coefficient version of a result proved by Lettington, 2010, extending a previous result by Andrews, 1963, showing that if B ⊂ R, d ≥ 2, is a...
