Cooling structure of motor

본 발명은 모터의 냉각구조에 관한 것으로, 축 결합공(11a)이 형성된 회전자프레임(11)의 내부에 고정자(12) 및 회전자(13)가 위치하는 모터에 있어서; 상기 축 결합공(11a)을 중심으로 그 동심원상에 통풍구(11b)를 형성하고, 상기 통풍구(11b)의 외측에는 회전자프레임(11) 내부로 유입되는 공기의 동압을 정압으로 변환시키는 동시에 흡입된 공기를 모터의 내부로 안내하도록 수개의 원심형 냉각 블레이드(14)를 설치하며, 상기 냉각 블레이드(14)의 외측에는 유체 속도에 의한 운동에너지를 압력에너지로 바뀌게 하는 확산공간부(S)를 형성함으로써, 냉각 블레이드의 회전에 의한 정압 상승의 효과가 크기 때문에 코일이 매우 촘촘하게 감겨 있고 회전자와 고정자 사이의 간격이 작아 고정자의 유동저항이 크더라도 항상 일정한 유량의 냉기를 공급할 수 있으며, 아울러 냉각 블레이드의 유동방향이 자연대류에 의한 유동방향과 일치하므로 모터의 냉각을 효율적으로 수행하게 된다. The present invention relates to a cooling structure of a motor, comprising: a motor in which a stator (12) and a rotor (13) are positioned inside a rotor frame (11) in which shaft coupling holes (11a) are formed; The vent hole 11b is formed on the concentric circle around the shaft coupling hole 11a, and the outside of the vent hole 11b converts the dynamic pressure of the air flowing into the rotor frame 11 into the static pressure and at the same time suctions the suction hole 11b. Several centrifugal cooling blades 14 are installed to guide the compressed air to the inside of the motor, and a diffusion space S for converting the kinetic energy due to the fluid velocity into pressure energy is provided outside the cooling blades 14. By forming the coil, the coil is very tightly wound and the gap between the rotor and the stator is small because the effect of the static pressure increase due to the rotation of the cooling blade is large. Since the flow direction of the blade coincides with the flow direction by natural convection, cooling of the motor is efficiently performed.

A motor includes a cylindrical housing, a cooling fan, and a rotating shaft. The cylindrical housing defines at least one upstream through hole at its circumferential wall. The cooling fan is mounted at the rotating shaft for generating airflow towards the cylindrical housing for dissipating the heat generated in the motor.
