Title (EN) MULTIPLEXED THREE-PHASE INVERTER-TYPE MOTOR DEVICE
(FR) DISPOSITIF DE MOTEUR DU TYPE À INVERSEURS TRIPHASÉS MULTIPLEXÉS
(JA) 多重3相インバータ型モータ装置
Abstract:
(EN) Provided is a multiplexed three-phase inverter drive motor device capable of switching the number of turns of a stator coil without adding a switching circuit for switching the connection of the stator coil. A plurality of three-phase inverters having a plurality of intermediate potential legs are connected to one or more three-phase coils. The duty ratios of the plurality of intermediate potential legs are equal to each other in serial mode. Each intermediate potential leg performs the same PWM switching operation. Preferably, one of the two of a plurality of three-phase coils placed adjacently in the axial direction is shifted by a half phase coil pitch in the circumference direction compared to the other.
(FR) L'invention concerne un dispositif de moteur à excitation par inverseurs triphasés multiplexés capable de commuter le nombre de spires d'une bobine de stator sans ajouter un circuit de commutation pour commuter la connexion de la bobine de stator. Une pluralité d'inverseurs triphasés dotés d'une pluralité de branches de potentiel intermédiaire est reliée à une ou plusieurs bobines triphasées. Les rapports de marche de la pluralité de branches de potentiel intermédiaire sont égaux entre eux en mode série. Chaque branche de potentiel intermédiaire effectue la même opération de commutation de MLI. De préférence, une des deux bobines parmi la pluralité de bobines triphasées, placées de façon adjacente dans la direction axiale, est décalée d'un demi-pas de bobine de phase dans la direction circonférentielle par comparaison à l'autre.
(JA) ステータコイルの接続を切替える切替回路を追加すること無しにステータコイルの巻数を切り替え可能な多重3相インバータ駆動モータ装置が提供される。複数の中間電位レグをもつ複数の3相インバータが一つ以上の3相コイルに接続される。複数の中間電位レグのデユーティ比は直列モードにおいて互いに等しい。各中間電位レグは同じPWMスイッチング動作を行う。好適には、軸方向に隣接配置された2つの複数の3相コイルの一方は他方と比べて周方向において半相コイルピッチだけシフトしている。
