For realizing above-mentioned purpose; A kind of motor housing of the utility model design; Comprise support, be arranged on the end cap of support one end and the fan housing that is connected with end cap, be densely covered with fin on the said support outer wall, the both ends of said support outer wall evenly are provided with four joint hinge stake positions respectively; The bottom of said support is connected with the hollow out fagging between two axial feets, the end face of said end cap is provided with radiating ribs.

Further, the lateral surface of said end cap evenly is equipped with four L type supports along circumference.

Further, the lateral surface two ends of said end cap evenly are provided with four boss along circumference, and said boss is provided with groove, and said four L type supports are positioned at groove.

Further, the both ends of said support outer wall evenly are provided with four joint hinge stake positions respectively.

Further, the junction of said fin root and support outer wall is an arc transition.

Again further, the pattern draft of said fin root is 3 °.

Be with the axial horizontal plane of support on the said support outer wall further, ± 45 ° position is provided with reinforcement.

Further, the outer wall junction of said terminal box stake and support is provided with the V-type wind deflector, and said V-type wind deflector is connected with fin.

Further, the bottom of said support is connected with the hollow out fagging between two axial feets.

Adopt the following advantage that the utlity model has of technique scheme:

1, the fin that on the outer wall of support, gathers has been strengthened the heat sinking function of support, whole support rapid heat dissipation; 2, be with the axial horizontal plane of support on the support outer wall ± 45 ° position is provided with reinforcement, strengthened the symmetry and the whole rigidity of support; 3, between two axial feets, be connected with the hollow out fagging in the bottom of support, also alleviated the blank weight of support when having reduced motor operational shock noise, reduced material cost; 4, the end face of end cap is provided with radiating ribs, and having increased whole motor, to spread hot side long-pending, has further strengthened the heat sinking function of support; 5, the lateral surface with end cap evenly is provided with four boss along circumference; Groove is set on boss, and the fan housing mounting bracket is arranged in the groove, has avoided on end cap, holing fan housing is installed; Improved the end cap working (machining) efficiency so significantly; Reduced the parts number, generalization improves, and more convenient production row produces; 6, the pattern draft of fin root is consistent is set to 3 °, and the mould molding is easy, can not produce burning into sand, stride sand; 7, the terminal box bottom is provided with the V-type wind deflector with the outer wall junction of support, can pass by the cold wind water conservancy diversion well, effectively reduces the local temperature rise of motor; 8, the both ends of support outer wall evenly are provided with four joint hinge stake positions respectively, have made things convenient for the lifting of any placement azimuth-drive motor.
