Method of assembling brushless electric motor for fan, involves closing electric connection between stator and printed circuit board (PCB) by plug connection, and preparing ground connection between stator unit and PCB by plug contacts

摘要

The method involves providing a flange for securing the housing (10). The PCB (13) is inserted into the housing, and the circuit board top face (26) is fixed with PCB screws on the housing. The ground connection between the PCB and housing is made by the PCB screw, so that the flange of the stator unit (9) is placed on the housing. The electric connections between the stator and the PCB are closed through the plug connections. One of the plug contacts is used for preparing the ground connection between the stator unit and the PCB.
