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.

    According to the present invention, a motor is insertedly installed in a motor housing having a receiving space in which the motor is received; a cooling channel through which a cooling fluid flows is formed in the motor housing; a hollow space is formed in a rotor shaft of the motor; convection passages are formed between the bottom surface of the motor housing and a rotor, between a magnetic pole portion of a motor stator and the outer wall of the stator, and between the rotor and a motor housing cover; a hollow space and upper and lower air holes are formed in the rotor shaft so as to allow upper and lower convection passages to communicate with each other; and a blade part is formed in the rotor shaft, whereby the rotation of the rotor shaft causes the blade part to forcibly blow air in the convection passages and thereby generate air convection between the upper and lower portions, so that the cooling efficiency can be improved.
