The present invention relates to a motor cooling device in which a motor is installed to be inserted into a motor housing having an accommodation space in which the motor is accommodated inside formed therein, a cooling channel in which a cooling fluid flows is formed at the motor housing, and a hollow is formed at a rotator shaft of the motor. The motor cooling device comprises: a convection passage between a bottom surface of the motor housing and a rotator, between a stimulation unit of a motor stator and a stator outer wall, and between the rotator and a motor housing cover; a hollow formed at the rotator shaft to interlock between upper and lower convection passages; upper and lower air holes; and a wind unit formed at the rotation shaft. Therefore, the wing unit forcibly blows air of the convection passage by rotation of the rotator shaft so as to generate air convection between upper and lower parts, thereby increasing cooling efficiency.

    본 발명은 내부에 모터가 수용되는 수용공간이 형성된 모터 하우징에 모터가 삽입 설치되고, 상기 모터 하우징에는 냉각유체가 유동되는 냉각채널이 형성되며, 모터의 회전자축에는 중공이 형성되며, 모터하우징 바닥면과 회전자 사이, 모터 고정자의 자극부와 고정자 외벽 사이, 회전자와 모터 하우징 덮개 사이의 대류 통로와, 상하부 대류 통로 사이를 연동시키도록 회전자축에 형성된 중공 및 상하부 공기구멍과, 회전자축에 형성된 날개부를 포함하여 구성함으로써, 회전자축의 회전에 의해 날개부가 대류통로의 공기를 강재 송풍시켜 상하부 사이의 공기 대류가 발생되어 냉각효율을 향상시킬 수 있도록 한 것이다.
