To provide a propeller propulsion device for a vessel capable of being using driving force of a dynamo-electric motor efficiently regardless of vessel speed of a vessel.SOLUTION: A propeller propulsion device includes: a first propeller, a second propeller, a first dynamo-electric motor, a second dynamo-electric motor, a controller, and a storage unit. The second propeller is arranged to be coaxial to the first propeller and is rotated in the reverse direction as the first propeller. The first propeller is driven by the first dynamo-electric motor and the second propeller is driven by the second dynamo-electric motor. The storage unit stores the combination of rotation numbers of the first propeller and the second propeller for every vessel speed where the total consumption of electric power for the first dynamo-electric motor and the second dynamo-electric motor is the optimum value. The controller respectively controls the first dynamo-electric motor and the second dynamo-electric motor based on data of the storage unit so that the total consumption power is the optimum value for every vessel speed during navigation of the vessel.SELECTED DRAWING: Figure 1

    【課題】船舶の船速に拘らず電動機の駆動力を効率良く利用することができる船舶のプロペラ推進装置を提供する。【解決手段】プロペラ推進装置は、第1のプロペラ、第2のプロペラ、第1の電動機、第2の電動機、制御部、記憶部を備えている。第2のプロペラは、第1のプロペラと同軸に配置されて第1のプロペラと逆向きに回転する。第1のプロペラは第1の電動機によって駆動され、第2のプロペラは第2の電動機によって駆動される。記憶部は、第1の電動機、及び、第2の電動機の合計消費電力が最適値となる船速毎の第1のプロペラと第2のプロペラの回転数の組み合わせを記憶する。制御部は、船舶の運航時に、船速毎に合計消費電力が最適値となるように、記記憶部のデータに基づいて第1の電動機と第2の電動機を夫々制御する。【選択図】図1
