Summary:To provide a synchronous electric machine, an associated propulsion drive, a boat, and a cooling method thereof.SOLUTION: A stator 27 includes a plurality of stacks 30 of laminations 300, and at least one channel 36 extending along the length of the stator and formed in the laminations, and two adjacent stacks of laminations are separated by spacers 31 or pins such that a discharge duct 32 connected to the channel is formed, and a machine housing 26 further includes a discharge opening 21, and a fluid injected into an air gap 29 from the end of the stator flows through the discharge duct and channel, and is discharged from the machine through an opening and cools the stator and a rotor.SELECTED DRAWING: Figure 4 【課題】同期電気機械、それに関連する推進用駆動装置、ボート、及びこれら機械の冷却方法を提供する。【解決手段】ステータ２７は、ラミネーション３００の複数の積層体３０と、ステータの長手方向に沿って延在する少なくとも１つのチャンネル３６であって、ラミネーションに形成された少なくとも１つのチャンネルとを含み、ラミネーションの隣接する２つの積層体は、チャンネルに接続された排出ダクト３２が形成されるように、スペーサ３１又はピンによって分離され、機械ハウジング２６は排出開口部２１をさらに含み、ステータの端部からエアギャップ２９に注入された流体は、排出ダクト及びチャンネルを流れ、機械から開口部を通じて排出され、ステータ及びロータを冷却する。【選択図】図４
