Motor and stator coil assembly and cooling fan thereof

Abstract

The utility model relates to a motor and a stator coil assembly and a cooling fan thereof. The stator coil assembly is combined with a seat, and the seat is combined with a rotating component, thereby forming the motor. The motor structure further comprises the cooling fan. The stator coil assembly comprises a plurality of wiring layers, each wiring layer is provided with a wiring contour, the outer sides and the inner sides of the wiring contours are respectively provided with a positioning area and a wiring area, the wiring areas of the wiring layers respectively form a coil, and the positioning areas of the wiring layers respectively form at least one conduction part for electrical conduction with the coils of different wiring layers. Therefore, no space needs to be reserved between two adjacent coils of the stator coil assembly to accommodate the conduction parts, and the number of winding turns or wire diameter of the coils can be increased.

Description

technical field [0001] The invention relates to a motor, its stator coil group and cooling fan, in particular to a stator coil group with a coil structure formed by wiring, a motor with the stator coil group and a cooling fan. Background technique [0002] Please refer to figure 1 As shown, the conventional motor stator 8 that is more common at present is disclosed. The motor stator 8 roughly includes several silicon steel sheets 81 , two insulating sleeves 82 and a coil group 83 . The several silicon steel sheets 81 are combined with each other by stacking; the two insulating sleeves 82 can be respectively combined with the upper and lower ends of each stacked silicon steel sheet 81; the coil group 83 is wound on the insulating sleeve by several coils 82 scheduled locations. [0003] However, the common existing motors on the market have gradually been developed and designed towards the direction of miniaturization, but the existing motor stator 8 is mainly composed of se...

Problems solved by technology

[0005] However, each wiring layer 921 of the stator coil group 9 must utilize the conducting portion 923 to be electrically connected, but the conducting portion 923 of each wiring layer 921 is arranged between two adjacent coils 922; therefore, the two-phase A space must be reserved between the adjacent coils 922 for accommodating the lead portion 923, so that the winding turns or wire diameter of the coil 922 are not easy to increase. When the stator coil group 9 is applied to the motor structure, it will affect the motor performance
