Abstract
(EN)
In the present invention a rotor position determination unit 10 uses induced voltages Vu, Vv, and Vw generated in each phase U, V, and W of an armature winding 5 to identify the rotor position. While a field current flowing in a field winding 3 is rising toward a target value (while the field current is changing over time), an induced voltage is generated in each phase of an armature winding 5 by means of a time derivative of the magnetic flux interlinked with the armature winding 5. The rotor position determination unit 10 identifies the rotor position (the d-axis of a rotor 4) on the basis of a table created by combining the polarity with the amplitude ratio of the induced voltage generated for each phase.

Dans la présente invention, une unité de détermination de position de rotor (10) utilise les tensions induites Vu, Vv et Vw générées dans chaque phase U, V et W d'un enroulement d'armature (5) en vue d'identifier la position du rotor. En même temps qu'un courant de champ circulant dans un enroulement de champ (3) s'élève vers une valeur cible (pendant que le courant de champ change au cours du temps), une tension induite est générée dans chaque phase d'un enroulement d'armature (5) au moyen d'une dérivée temporelle du flux magnétique lié à l'enroulement d'armature (5). L'unité de détermination de position de rotor (10) identifie la position du rotor (l'axe d d'un rotor (4)) sur la base d'une table créée en combinant la polarité au rapport d'amplitude de la tension induite générée pour chaque phase.

回転子位置判断部10は、電機子巻線5の各相U,V,Wに発生する誘起電圧Vu,Vv,Vwを利用して回転子位置を特定する。界磁巻線3を流れる界磁電流が目標値に向かって上昇している間(界磁電流が時間的に変化している間)は、電機子巻線5に鎖交する磁束の時間微分によって、電機子巻線5の各相に誘起電圧が発生する。回転子位置判断部10は、各相に発生する誘起電圧の振幅比に極性を組み合わせて作成したテーブルに基づいて、回転子位置(回転子4のd軸)を特定する。
