Including bracket, fixation hole is opened up in the corner of the bracket, is also extended to form in the side of the bracket for filling
Second boss with magnet ring；
The specific structure of the metal component is as follows：
Including pedestal, in extending outward to form first boss on the pedestal, in the not set first boss of the pedestal
Surface opens up the through hole for connecting winding leads, in opening up the counterbore for connecting frequency converter in the first boss.
As a further improvement of the above technical scheme：
The metal component is every group 3, wherein one group of metal component is close to the center and along the circumferential direction of insulating component
Arrangement, another group of metal component are to be located at insulation structure referring to the edge for being offset to insulating component with previous group metal component
