Abstract
Description
ハウジングに連結されており、少なくとも2つのグループの物理的に分離された複数の巻き線を有するステータと、
ステータ内に同軸に回転可能に取り付けられており、複数の永久磁石を有しているロータと、
複数の巻き線内の電力と、電力の位相とを制御する制御手段と、
複数の巻き線を流れる電流と、ロータのステータに対する角度位置とを計測する計測手段と、
制御手段と計測手段とに接続され、電気モータを動作させる動作手段と、
動作手段に接続され、データをハウジングの外部に通信するデータ通信手段と、
を備えている電気モータを提供する。本発明はさらに、回転軸線を有している車軸を有している車輪と、電気モータの回転軸線を有しているロータを備えている電気モータとを備え、電気モータは、電気モータの回転軸線が車輪の回転軸線の上方に配置された状態で、乗り物内に配置されている乗り物に関する。
1.パワーモジュール
最下位の階層では、複数のIGBT主電流モジュールが使用された。IGBT主電流モジュール内に存在する構造は、それ自体信頼性が高く、低熱放射と最適な効率を保証する。主電流モジュールは、巻き線を流れる電流を調整する。巻き線は、3つのグループに分けられ、各々の位相は異なっている。巻き線あたり2つの主電流モジュールが設けられている。主電流モジュールは、上位の階層によって制御されており、それは以下のとおりである。
2.電流レギュレータ
第2の階層では、2つのIGBT主電流モジュールが1つの電流レギュレータに接続され、電流レギュレータによって制御されている。ホール原理によって動作する独立した電流センサ(ホールセンサ)と共に、電流レギュレータは、付随しているモータ巻き線内の電流を制御する独立した最終階層を構成している。この階層では、モジュールと電流レギュレータは、動作用電子部品からすでに電気的に分離されている。2つの主電流モジュールを有している電流レギュレータとホールセンサは、さらに4Q−モジュールと呼ばれる。電流レギュレータを備えている主電流モジュールは制御装置を構成している。制御装置は巻き線ごとに存在している。
3.ベクトルジェネレータ
ベクトルジェネレータは、制御値を複数のいわゆる4Q−モジュール(階層1と2)に供給し、それによって、4Q−モジュールは同期モータの巻き線よって磁場ベクトルを発生して、トルクのモーメントを定める。
4.CPUつまり中央処理装置
最初の3つの階層は一緒に電気モータ内に収容されている。CPUは、電気モータの外側に配置され、光学リングデータバスライン(ORDABUL)または他のコンピュータネットワーク接続によって乗り物上に存在する可能性のある本発明のさまざまなモータと通信する。右左折をして(taking bends)、運転の考え方全体(complete driving concept)を診断するときに、推定航法(odmetrics)によって、走行した道路について、AGV(無人搬送車)に必要な計算を実行することもできる。各階層は、運転状態にとって重要な情報を監視しCPUに報告する。エラー報告は、上層の階層に即座に報告され、上層の階層は、損傷が発生する前に必要な措置を講じることで対応する。上層の階層は、エラーに対して正しく応答する緊急プログラムを起動することができる。その結果、1つのモジュール内のエラーが乗り物全体に影響することはほとんどない。
