<p>A miniature motor includes a base (10,40) having a layout layer (11,41) with two faces spaced along an axis. The layout layer (11,41) includes a coil unit (13,43). The base (10,40) further includes an outer layer (12,42) provided on one of the faces of the layout layer (11,41). Further, a shaft seat (20) is provided on the base (10,40). A rotor (30) includes a shaft (31) and a permanent magnet (32). The shaft (31) is coupled to the shaft seat (20) and rotatable about the axis. The permanent magnet (32) is aligned with the coil unit (13,43). An axial air gap (36) is formed between the permanent magnet (32) and the outer layer (12,42) of the base (10,40). The coil unit (13,43) is integrated into the base (10,40) . Thereby the axial height of the miniature motor can be reduced and the structure of the miniature motor can be simplified.</p> |
