Abstract

본 발명은 영구자석 동기모터의 냉각장치를 개시한다.The present invention discloses a cooling device for a permanent magnet synchronous motor.

본 발명은 중앙에 그 냉매 체널이 냉매가 공급되는 냉매입구와 연결되도록 형성되고, 좌.우측에 냉매가 공급되어 고정자와 회전자가 냉각되도록 냉매 구멍이 각각 형성되는 축과; 바깥둘레에 냉매가 배출되도록 그 챔버와 연결되는 냉매 출구가 형성되는 하우징을 포함한다.The present invention relates to a shaft comprising: a shaft formed at a center thereof so that a coolant channel is connected to a coolant inlet through which a coolant is supplied; And a housing in which a coolant outlet connected to the chamber is formed so that the coolant is discharged outwardly.

따라서, 고정자와 회전자가 축을 통하여 공급되는 냉매에 의해 냉각되어 냉각 효과가 우수하게 향상되므로, 제품의 소형화 제작이 용이하게 가능해지는 것이다. 또한, 자석들의 감자가 효과적으로 제거되어 제품의 효율 및 신뢰성이 현저히 향상되는 것이다.Therefore, since the stator and the rotor are cooled by the refrigerant supplied through the shaft, the cooling effect is excellently improved, and therefore, the miniaturization and manufacture of the product can be easily performed. In addition, the demagnetization of the magnets is effectively removed, thereby significantly improving the efficiency and reliability of the product.
