Abstract

본 발명은 유도전동기의 냉각팬에 관한 것으로, 특히 유도전동기의 온도에 따라 냉각팬의 속도를 가감제어함으로써 전동기의 냉각성능을 증진해 유도전동기의 제어성능을 향상하는 유도전동기의 냉각팬 속도제어장치에 관한 것이다.The present invention relates to a cooling fan of an induction motor. More particularly, the present invention relates to a cooling fan speed control device for an induction motor which improves the cooling performance of the induction motor by improving the speed of the cooling fan according to the temperature of the induction motor, .

본 냉각팬의 속도제어장치는 전동기의 온도를 감지하여 그 온도에 따라 냉각팬의 속도를 가변적으로 제어함으로써 소음과 진동을 감소시킨 효과를 갖는다. 종국적으로는 이로 인해 전력소비가 줄어들고 내구성이 향상되는 잇점을 갖는다.The speed control device of the cooling fan senses the temperature of the motor and variably controls the speed of the cooling fan according to the temperature, thereby reducing noise and vibration. Ultimately, this has the advantage of reducing power consumption and improving durability.
