Title (EN) CONSEQUENT MOTOR
(FR) MOTEUR CONSÉCUTIF
(JA) コンシクエント型モータ
Abstract:
(EN) The number of a plurality of coils of a consequent motor is a multiple of 6 and the number of a plurality of magnetic poles is an odd number of 3 or more. A control unit includes a first inverter that controls a current supplied to a first coil group among the plurality of coils and a second inverter that controls a current supplied to a second coil group radially opposed to the first coil group among the plurality of coils. A first harmonic current including a primary harmonic current as a main wave current is superimposed on a fundamental current of a d-axis current of the first coil group by the first inverter. A second harmonic current including a primary harmonic current as a main wave current is superimposed on a fundamental current of a d-axis current of the second coil group by the second inverter. The peak phases of three-phase alternating currents supplied to the first coil group and the second coil group are shifted with respect to each other, and the zero-cross positions of the currents are the same.
(FR) Selon l'invention, le nombre d'une pluralité de bobines d'un moteur consécutif est un multiple de 6 et le nombre d'une pluralité de pôles magnétiques est un nombre impair de 3 ou plus. Une unité de commande comprend un premier onduleur qui commande un courant fourni à un premier groupe de bobines parmi la pluralité de bobines et un second onduleur qui commande un courant fourni à un second groupe de bobines radialement opposé au premier groupe de bobines parmi la pluralité de bobines. Un premier courant harmonique comprenant un courant harmonique primaire en tant que courant d'onde principal est superposé sur un courant fondamental d'un courant d'axe d du premier groupe de bobines par le premier onduleur. Un second courant harmonique comprenant un courant harmonique primaire en tant que courant d'onde principal est superposé sur un courant fondamental d'un courant d'axe d du second groupe de bobines par le second onduleur. Les phases de crête des courants alternatifs triphasés fournis au premier groupe de bobines et au second groupe de bobines sont décalées les unes par rapport aux autres, et les positions de passage à zéro des courants sont les mêmes.
(JA) コンシクエント型モータの複数のコイルの数が6の倍数であり、複数の磁極の数が3以上の奇数である。制御部が、前記複数のコイルのうち第1コイル群に供給される電流を制御する第1インバータと、前記複数のコイルのうち前記第1コイル群と径方向に対向する第2コイル群に供給される電流を制御する第2インバータと、を備える。前記第1インバータにより、前記第1コイル群のd軸電流の基本波電流に対して、1次高調波電流を主要波電流として含む第1高調波電流が重畳される。前記第2インバータにより、前記第2コイル群のd軸電流の基本波電流に対して、1次高調波電流を主要波電流として含む第2高調波電流が重畳される。前記第1コイル群および前記第2コイル群に供給される3相交流電流のピーク位相がずれ、ゼロクロス位置が同じである。
