PROBLEM TO BE SOLVED: To provide a cooling device of a motor which accumulates a pressure of an oil without losing energy for driving a vehicle and supplies the oil to a motor with the pressure of the oil accumulated during low speed running or vehicle stop.SOLUTION: A cooling device of a motor according to the invention includes: an in-wheel motor 300 which drives a vehicle; a pressure accumulation oil pump 420 which is connected with a driving wheel of the vehicle and absorbs energy generated during deceleration of the vehicle to be driven thereby; and a pressure accumulation mechanism 440 in which an internal pressure increases when an interior part is filled with an oil by driving of the pressure accumulation oil pump 420, the pressure accumulation mechanism 440 supplying the oil filling the interior part to the in-wheel motor 300 when the internal pressure is released.

    【課題】車両を駆動するためのエネルギーを消失することなくオイルを蓄圧し、低速走行時又は車両停止時に蓄圧したオイルをモータへ供給する。【解決手段】本発明に係るモータの冷却装置は、車両を駆動するインホイールモータ300と、車両の駆動輪と連結され、車両減速時のエネルギーを吸収して駆動される蓄圧用油ポンプ420と、蓄圧用油ポンプ420の駆動により油が内部に充填されると内圧が上昇し、内圧が開放されると内部に充填された油をインホイールモータ300へ供給する蓄圧機構440と、を備える。【選択図】図2
