To provide a drone drive unit capable of cooling a motor that rotates a rotor blade with a relatively lightweight configuration.SOLUTION: A drone drive unit includes a rotor blade fixed to a shaft, a motor that rotates the shaft, and a cooling mechanism that radiates heat generated by the motor outside the motor by circulating a coolant. The cooling mechanism includes an axial fan that rotates following the shaft and circulates the coolant.SELECTED DRAWING: Figure 2

    【課題】回転翼を回転させるモータを比較的に軽量な構成で冷却できるドローン用駆動ユニットを提供する。【解決手段】ドローン用駆動ユニットは、シャフトに固定された回転翼と、シャフトを回転させるモータと、冷媒の循環によってモータの発熱をモータの外側で放熱する冷却機構と、を備える。冷却機構は、シャフトに従動して回転し、冷媒を循環させる軸流ファンを有する。【選択図】図2
