Title:
CENTER SUPPORT SHAFT
Document Type and Number:
WIPO Patent Application WO/2013/107043
Kind Code:
A1
Abstract:
A center support shaft (1) comprising an annular housing (100) having running between two ends thereof a pass cavity. Arranged on the outer surface of the annular housing (100) are several installation structures (101) respectively used for fixing several discrete stators of an external rotor motor and capable of shielding the several stators from electromagnetic interferences between each other. The several installation structures (101) used for installing the discrete stators of the external rotor motor are arranged on the outer surface of the annular housing (100) of the center support shaft; this allows the multiple stators to be installed directly onto the multiple installation structures, obviates the need for additional complex structure, provides a simplified structure and reduced costs, and ensures that the stators are connected securely, so that the stators can operate steadily even in a vibratory environment. In addition, the installation structures are capable of shielding the electromagnetic interferences between the stators, thus ensuring normal operation of the stators.
