Abstract
【解決手段】
可変負荷要求に対して複数のモータ(16−1,16−2,16−3)を変速制御する装置が提供される。この装置は、定出力電源(22)と、この定出力電源との接続のためのスイッチ(20−1,20−2,20−3)を含む電気回路(18)を有する複数のモータと、を有する。この装置は、さらに複数のモータをそれぞれ変速状態で駆動する変速駆動装置(12)を含み、これらの複数のモータは、変速駆動装置との接続のためのスイッチ(14−1,14−2,14−3)をそれぞれ有する。各々の複数のモータは、負荷要求に応じて変速または定速のいずれかでそれぞれ駆動されるように、上記スイッチによって選択的に変速駆動装置と定出力電源に電気的に接続される。
