Abstract
A stator for an external rotor motor, containing at least a stator core (1) having multiple teeth (4) and a shaft (3), a stator winding (2), multiple slots (5), a pair of end plates (6), a patch board (7) having a first through hole (8), a power wire (11), and a fastening device (9). The shaft (3) is disposed at the center of the stator core (1). The slot (5) is formed between adjacent teeth (4) of the stator core (1). The stator winding (2) is received in the slot (5) and wrapped around the teeth (4). The patch board (7) is disposed above one of the end plates (6). The shaft (3) passes through the first through hole (8) of the patch board (7). The fastening device (9) is disposed at the top of the patch board (7) and operates to fix the weld-connecting portion (10).
