Description
第1の実施の形態の複合磁性材料は、Fe、Co及びNiからなる群から選ばれる少なくとも一つの第1の元素を含む磁性金属相、及び、主面を有する平面型の構造の複数の磁性体と、酸素(O)、炭素(C)、窒素(N)及びフッ素(F)からなる群から選ばれる少なくとも一つの第2の元素を含む介在相と、を有し、表面に平面を有する磁性材料と、板状の補強材と、を備える複合磁性材料において、前記主面が、前記平面に対して略平行に配向し、前記平面内において、方向による保磁力差を有する、複合磁性材料である。
なお、図5~図9は、磁性体2、磁性材料の配置に関するあくまで一例を示したものであって、必ずしもこれに限定されるものではない(図5~図9以外の配置も考えられる)。本実施形態の基本的な概念が同じであれば、配置は図と全く同じである必要はない。
また、ここまで、第1、第2、第3、第4までの磁性材料について記載してきたが、更に磁性材料の数を増やしても構わない。第5、第6、と、高強度化と磁気特性の向上のために、必要に応じて磁性材料の数を増やす事が好ましい。
一つの扁平磁性金属粒子が凹部と凸部の両方を有していても良い。尚、凹部又は凸部のアスペクト比とは、長軸の長さ/短軸の長さである。つまり、凹部又は凸部の幅よりも長さのほうが大きい(長い)場合、アスペクト比は長さ/幅で定義され、長さよりも幅のほうが大きい(長い)場合、アスペクト比は幅/長さで定義される。アスペクト比が大きいほうが、磁気的に一軸異方性(異方性)を有しやすくなり、より好ましい。
化学式(1)中、Rはビフェニル、トリフェニル、テトラフェニルのいずれかの構造、R’は構造内に少なくとも一つ以上の芳香環を有する構造を示す。
第2の実施の形態のシステム及びデバイス装置は、第1の実施の形態の複合磁性材料を有するものである。したがって、第1の実施の形態と重複する内容については記載を省略する。このシステム、デバイス装置に含まれる複合磁性材料の部品は、例えば、各種モータや発電機などの回転電機(例えば、モータ、発電機など)、変圧器、インダクタ、トランス、チョークコイル、フィルタ等のコアや、回転電機用の磁性楔(磁性くさび)等である。図12は、第2の実施の形態のモータシステムの概念図例である。モータシステムは、回転電機システムの一例である。モータシステムとは、モータの回転数や電力(出力パワー)を制御する制御系を含めたシステムの事である。モータの回転数を制御する方式としては、ブリッジサーボ回路による制御、比例電流制御、電圧比較制御、周波数同期制御、PLL(Phase Locked Loop:位相同期ループ)制御、等による制御方法がある。一例として、PLLによる制御法について図12に示してある。PLLによるモータの回転数を制御するモータシステムは、モータと、モータの回転の機械的変位量を電気信号に変換してモータの回転数を検出するロータリーエンコーダと、ある命令により与えられたモータの回転数とロータリーエンコーダにより検出されたモータの回転数を比較しそれらの回転数差を出力する位相比較器と、当該回転数差を小さくするようにモータを制御するコントローラと、を備える。一方、モータの電力を制御する方法としては、PWM(Pulse Width Modulation:パルス幅変調)制御、PAM(Pulse Amplitude Modulation:パルス電圧振幅波形)制御、ベクトル制御、パルス制御、バイポーラ駆動、ペデスタル制御、抵抗制御、等による制御方法がある。またその他の制御方法として、マイクロステップ駆動制御、多相駆動制御、インバータ制御、スイッチング制御、等の制御方法がある。一例として、インバータによる制御法について図12に示してある。インバータによるモータの電力を制御するモータシステムは、交流電源と、交流電源の出力を直流電流に変換する整流器と、当該直流電流を任意の周波数による交流に変換するインバータ回路と、当該交流により制御されるモータと、を備える。
