To provide a rotary electric machine unit, a rotary electric machine, and a vehicle that are capable of cooling during hill-climbing without increasing an amount of coolant discharge during a normal time.SOLUTION: A rotary electric machine unit 20 comprises: a coolant passage 43 and a coolant supply pipe 33 that sends a coolant toward a rotary electric machine main body; first cooling dropping pipes 31a to 31c that discharge the coolant in the coolant supply pipe 33 above the rotary electric machine main body; a second cooling dropping pipe 32 that discharges the coolant in the coolant supply pipe 33 in front of the rotary electric machine main body; a coolant switching mechanism 35 for switching a channel to the second cooling dropping pipe 32; and an ECU 2 (hill-climbing determination unit) for determining a hill-climbing of a vehicle. The hill-climbing determination unit discharges the coolant from the second cooling dropping pipe 32 by opening the coolant switching mechanism 35 when it is determined that the vehicle is in hill-climbing.SELECTED DRAWING: Figure 2
【課題】通常時の冷媒吐出量を増やすことなく、登坂時の冷却が可能となる回転電機ユニット、回転電機および車両を提供する。【解決手段】回転電機ユニット20は、回転電機本体に向け冷媒を送り込む冷媒通路43および冷媒供給管33と、冷媒供給管33の冷媒を回転電機本体の上部に放出する第1冷却用滴下パイプ31a〜31cと、冷媒供給管33の冷媒を回転電機本体の前方部に放出する第2冷却用滴下パイプ32と、第2冷却用滴下パイプ32への流路を開閉する冷媒切替機構35と、車両の登坂を判定するECU2(登坂判定部)と、を備え、登坂判定部は、車両が登坂中と判定した場合、冷媒切替機構35を開成して第2冷却用滴下パイプ32より冷媒を放出する。【選択図】図2
