Abstract
【解決手段】本発明は、モータ軸の空気力学的支持を有する電気モータの駆動回路に関する。この駆動回路は、電気エネルギを蓄えるための少なくとも1つの蓄積手段を備え、電源電圧又は中間回路電圧の障害の際に、少なくとも時々は空気支持に必要なモータ軸の最小速度を得るために、蓄積手段によって電気モータが電気エネルギの供給を受けることができる。
【選択図】図1
Description
それが中間回路電圧が所定の下限値を下回ったことを認識するように設計され得る。この場合、電気エネルギは、少なくとも1つの蓄積手段から電気モータへの電圧供給を支援するために、自動的に供給され得る。これにより、中間回路電圧がほぼ一定に維持され得る。
本発明に係る駆動回路と同じ特徴及び効果を有する。したがって、説明の繰り返しを省略する。
