An incorporation method of sensorless algorithms: Signal injection and back EMF based methods
The 2010 International Power Electronics Conference - ECCE ASIA -, 2010This paper considers the smooth transition method between the signal injection and the back-EMF based sensorless algorithm for an interior(salient) permanent-magnet synchronous machines(IPMSMs). For the starting algorithm, signal injection techniques are used in the zero-speed and low-speed regions, and the back-electromotive force (EMF) based ...

Thermodynamic Properties of AgIn2Te3I and AgIn2Te3Br, Determined by EMF Method
Russian Journal of Physical Chemistry A, 2018Differential thermal analysis (DTA), X-ray diffraction (XRD), and electromotive force (EMF) are used to triangulate Ag–In–Te–I(Br) systems in the vicinity of compounds AgIn2Te3I and AgIn2Te3Br. The three-dimensional position of the AgIn2Te3I–InTe–Ag2Te–AgI and AgIn2Te3Br–InTe–Ag3TeBr phase areas with respect to the figurative points of silver is used ...

A Two-emf Method for the Comparison of Resistances
Review of Scientific Instruments, 1954A method of comparing resistances is described in which two sources of emf, each with an associated dropping resistor, are connected in series with two resistors to be compared, in such a way that the latter are not adjacent. The circuit may then be adjusted so that the potentials at the two ends of one of these resistances are equal to the potentials ...

High temperature stability of SrY2O4 by SrF2-based emf method
Materials Letters, 2002Abstract The only inter oxide, SrY 2 O 4 in the Y 2 O 3 –SrO system was synthesized at as low a temperature as 1120 K by a hybrid polymeric-gel cum auto-combustion method. For determining the high temperature stability of SrY 2 O 4 the emf of the galvanic cell, Pt , SrO , SrF 2 , O 2 | SrF 2 | O 2 ...

Detection of Microstructure Change in Glass by an Emf Method
Journal of the Ceramic Association, Japan, 1968加熱過程で分相, 結晶化などの微構造変化を起すガラス試験片と, かような変化をすでに完了して熱的に安定化された標準試験片とを密に接触させ, これに白金電極を組合せて構成した電池系が昇温過程で発生する起電力を測定した. この測定結果から得られた起電力-温度曲線を同じガラス試料に対する電子顕微鏡観察とX線分析結果と対照し, 起電力変化と微構造変化との対応性を検討した.その結果, 起電力-温度曲線に現われる変化によって分相および結晶化の核形成をも含んだ微構造変化の全過程の進行状態を読みとることのできることが明らかとなった.
