Description
なし
本発明は、直流電動機に関する。
エネルギコストが上昇し、かつ供給が減少し続けているので、特に電動機用のエネルギのより効率的な利用に関するかなりの必要性がある。電動機は多くの装置に動力を供給するので、所与の入力エネルギに対して電動機の電力出力を改善することは、エネルギコストのかなりの節約を意味するであろう。
一実施形態において、本発明は、非磁化コアを囲む複数のワイヤコイルを含む固定子と、自身に永久磁石が埋め込まれた回転子であって、固定子に隣接して配置され、かつ回転可能な駆動軸に取り付けられた回転子と、電源と、回転子に動作可能に接続された位置センサと、ワイヤコイルへの電気エネルギの分配を制御するために、電源、位置センサおよびワイヤコイルに動作可能に接続された制御回路と、を含む多相電動機であって、制御機構が、第1のコイルから第2のコイルに電荷を転送する多相電動機である。
好ましい実施形態の下記の説明は、本質的にはあくまで例示的なものであり、決して、本発明、その用途または使用法を限定するものではない。
