The invention discloses a flat copper wire motor armature winding structure. The structure includes a stator core having multiple slots and multiple winding layers in the slots, wherein each winding layer is formed by multiple flat copper wire conductor coils, the flat copper wire conductor coils include a phase winding end power supply lead conductor coil, a flat copper wire neutral connection point conductor coil and a U-shaped flat copper wire conductor coil, a phase winding end power supply lead conductor includes a conductor turning end portion and a conductor leg portion connecting the conductor turning end portion, a flat copper wire neutral connection point conductor includes a conductor turning end portion, a conductor leg portion connecting the conductor turning end portion and aconnecting portion conductor electrically connecting a conductor portion of each phase winding power supply lead, the flat copper wire conductor coils can include three different pitch types of conductor coils, namely first conductor, second conductor and third conductor coils, the multiple flat copper wire conductor coils can form eight winding groups, and the eight winding groups can be linkedtogether in parallel.
Description
technical field [0001] The invention relates to a motor stator assembly in the electrical field, in particular to a structural arrangement of a flat copper wire motor armature winding. Background technique [0002] The armature winding of the flat copper wire motor in the prior art has the technical problem that there are too many types of flat copper wire conductor coils with different shapes, resulting in complicated conductor coil layout, too many connecting wires at the end of the stator armature winding, and the stator armature winding Process problems such as increased difficulty in assembly and welding are not conducive to manufacturing. [0003] Compared with the traditional round copper wire motor, although the use of flat copper wire conductor coils in the stator slot can significantly improve the slot fill rate of the motor. However, due to the skin effect, the effective cross-sectional area of the flat copper wire conductor coil is reduced. Especially when th...
