To provide a rotating motor which can efficiently cool a coil end without having complicated piping for a cooling medium within the rotating motor and an in-wheel motor driving device with the rotating motor.SOLUTION: A rotating motor has a stator 5 and a rotor. The stator 5 has a stator core 8 in which a plurality of tooth parts 7a are arranged in an annular form, and a stator coil 9 wound around each of the tooth parts 7a. A cooling medium passage 36 for cooling and a guide plate 37 are provided. The cooling medium passage 36 guides a cooling medium R to an upper of a coil end 9a located above. The guide plate 37 receives the cooling medium R discharged from a discharge port 36c of the cooling medium passage 36 on a cooling medium guide face 38, and guides the cooling medium R in a circumferential direction of the stator 5 to be flown to the coil end 9a. At a position just below the discharge port 36c in the cooling medium guide face 38, a projection portion 37d preventing the cooling medium R from flowing reversely in the circumferential direction is provided.SELECTED DRAWING: Figure 4

    【課題】回転電動機の内部に冷却媒体用の複雑な配管を設けることなく、コイルエンドを効率的に冷却することができる回転電動機およびこの回転電動機を備えたインホイールモータ駆動装置を提供する。【解決手段】回転電動機は、ステータ5とロータとを備える。ステータ5は、複数の歯部7aが円環状に並ぶステータコア8、および各歯部7aにそれぞれ巻回されたステータコイル9を有する。冷却用の冷却媒体流路36と案内板37とを有する。冷却媒体流路36は、上部に位置するコイルエンド9aの上方に冷却媒体Rを導く。案内板37は、冷却媒体流路36の吐出口36cから吐出される冷却媒体Rを、冷却媒体案内面38で受け、ステータ5の円周方向に案内してコイルエンド9aに流す。冷却媒体案内面38における吐出口36cの直下の位置に、冷却媒体Rが円周方向に逆流するのを阻害する突起部37dが設けられている。【選択図】図4
