[Prior Art] Conventional inner rotor thin motors and thin vibration motors (refer to US 6,417,589 and US 6,479,914) are mostly radial magnetic fluxes and have a structure with core windings. Then, in order to make the motor thinner, the inner rotor thin motor is mostly designed with an axial magnetic flux and a coreless design (refer to US Pat. No. 6,534,886, uS7, i57, 823 and US Pat. No. 6,005, 324). Magnetic flux and no iron core to thin the motor vibration motor design. In US 7,157,823, the motor is further miniaturized by providing a concentrated winding winding coil and a line wiring arrangement on the thin vibration motor circuit board. The inner rotor thin motor adopts the axial magnetic flux design, which can effectively thin the motor. However, since the magnet has only one side corresponding winding with suction, only one single-sided stator provides magnetic conduction, and there is bearing wear and low efficiency. problem. In order to improve the shortcomings caused by the magnetism of only one side of the magnet, the inner rotor and the axial flux type 4 motor can adopt a sandwich structure of double-sided windings (refer to US 6,940,206). Such an axial flux thin-film type motor having a double-sided winding structure, whether using a winding coil configuration or applying a winding line to a circuit board. Another sixty, because of its structure with double-sided winding lines, it is necessary to have another line connection design between the two side winding lines. Therefore, it is necessary to provide an innovative and progressive axial flux winding and 201123686 to solve the above-mentioned problem and the motor including the axial flux winding device. SUMMARY OF THE INVENTION The present invention provides an axial flux winding device that is disposed on a flexible substrate and a winding set of a relatively n (four) flux winding device disposed in a rotor. The flexible substrate has at least a plate and at least a bridge portion, and the at least two carrier plates are located on opposite sides of the rotor, and the bridge portion connects the at least two carrier plates. The winding group has at least two winding units and at least one internal line connecting the at least two winding units. Each winding unit is disposed on a corresponding carrier and has at least one winding structure. 'An internal line is located in the at least one bridge. The invention further provides an axial flux motor comprising a rotor, a housing and the axial flux winding arrangement described above. The rotor has a shaft. The carrier on the side of the 〆 rotor has a __through hole for the shaft to pass through. The housing has a base and a cover, and the shaft passes through at least the through hole and is disposed on the base such that the winding device is located between the cover and the cover. # The winding group and the flexible substrate can be implemented in the same process to simplify the line distribution and fabrication process of the axial flux winding device, and to improve the additional wiring connection between the winding units The problem is that the reduction of resources is reduced, the cost is reduced, the structure of the motor (4) is reduced, and the space is thinned to save space. Moreover, through the design and configuration of the axial flux winding device of the present invention, a concentrated m-distribution effect can be achieved, and the winding group can be a multi-layer structure, so that the winding can be increased. Furthermore, the axial flow flux winding device of the shaft axial flux winding device can be effectively profiled and can be bent and flexed to the magnetic flux of the rotor. The size of the motor is small.
