The flat copper wire is used for wire embedding, the conductors in the groove are basically in surface contact, compared with the point contact of round copper wires, the gaps among the copper wires during wire embedding are greatly reduced, the copper clean groove full rate is improved by about 15-20%, the height of an end winding can be reduced by about 15%, the surface contact mode is more favorable for heat transfer, and the heat radiation performance is more excellent; in addition, the flat copper wire conductor has higher rigidity and better NVH performance of the motor. For a new energy automobile pursuing large torque output, high efficiency and comfort, the flat copper wire inherently has great advantage potential.
While the direct current resistance is reduced by increasing the wire diameter and the slot fill factor, some adverse effects are brought. The working principle of the permanent magnet synchronous motor is that a stator winding is electrified with three-phase alternating current to generate a rotating magnetic field, and the rotating magnetic field is coupled with a rotor magnetic field to generate torque so as to drive a rotor to rotate. But when the conductor passes through the alternating current, can produce the eddy current effect, including skin effect and proximity effect, the influence that the round copper line received because the wire line footpath is less and wiring dispersion has offset most effect is less, and flat copper line wire footpath is big, and the rule of arranging, and skin effect is obvious under the high frequency (high-speed) operating mode, and current distribution is inhomogeneous and concentrates on near stator notch position, and conductor resistance increases, and the loss increases.

Detailed Description
Referring to fig. 1 to 9 in combination, according to an embodiment of the present invention, there is provided a flat wire motor stator assembly, including a stator core 1, a plurality of stator teeth 12 arranged at intervals along a circumferential direction of a yoke ring 11 of the stator core 1, a stator slot formed between two adjacent stator teeth 12, a flat wire 2 (specifically, for example, a flat copper wire) wound in the stator slot 13, the stator slot including a plurality of parallel slot segments arranged in sequence from inside to outside along the radial direction of the stator core 1, and a circumferential width of each of the parallel slot segments gradually increases from inside to outside along the radial direction of the stator core 1. As described in the background art, in the stator assembly of the flat-wire motor in the prior art, under a high-frequency high-speed working condition, the influence of the eddy current effect on the conductor closer to the notch of the stator slot is larger, so that the actual utilization rate of the conductor is reduced, and therefore the actual utilization rate of the conductor is improved and the alternating current loss of the conductor is reduced by reducing the area of the flat-wire copper close to the notch. Specifically, in order to better utilize the designable area, the width of the slot body close to the slot is reduced, because the flat-wire motor generally adopts the design of parallel slots, the tooth width which is closer to the interior of the stator is smaller, and the width of the slot body close to the slot end is reduced, so that the width of the stator teeth at the slot end is increased, and in turn, the part which is originally reduced by the conductor material close to the slot end is supplemented to the part which is close to the yoke part of the stator, the size of the slot width which is close to the yoke part is increased, and the width of the slot body is reduced, so that the length of the slot body is reduced, and the whole width of the slot body is more uniform. Compared with the parallel stator slot structure (shown in fig. 3) with the same slot width along the radial direction of the stator in the prior art, simulation verification proves that under the same material consumption of a copper conductor (namely a flat copper wire), the armature alternating current loss is smaller under a high-speed working condition (close to more than 6000 rpm) (shown in specific reference in fig. 4 and 5), the width of the stator tooth body close to the notch end is widened, the problem that the local magnetic density of the tooth body is too saturated is optimized (shown in specific reference in fig. 8 and 9), the magnetic potential loss is reduced, the torque curve (shown in specific reference in fig. 6 and 7) shows that the optimized stator topology has larger torque under the same working condition, the torque ripple is smaller due to more uniform magnetic density, the effect is more obvious (2.8% is reduced to 1.8%), and the design correctness and the superiority of the topology of the invention are verified (the current torque and the torque ripple are larger than those of fig. 6 and 7) The small value shows that the torque of the prior structure in the rated current and the peak current is lower than that of the prior structure in the invention (figure 7), the torque ripple is higher than that of the prior structure, and the improvement effect of the prior structure on the torque performance is reflected).
The parallel slot segments include a first parallel slot segment 131 and a second parallel slot segment 132, the first parallel slot segment 131 and the second parallel slot segment 132 are sequentially arranged from inside to outside along a radial direction of the stator core 1, the flat wires 2 include a first flat wire 21 wound in the first parallel slot segment 131 and a second flat wire 22 wound in the second parallel slot segment 132, the first flat wire 21 in the first parallel slot segment 131 is provided with n layers, each layer of the first flat wire 21 has a circumferential width of L1 and a radial length of L2, L1 is (1.2-1.3) L2, and n is an integer not less than 1, specifically, as shown in fig. 1, at this time, n is 4, the inventor finds that a width ratio has a large influence on alternating current loss and local magnetic density of the flat wire motor, and when the width ratio is 1.2-1.3, the alternating current loss and the local magnetic density are more uniform.
In some embodiments, the first parallel groove segment 131 has a circumferential width L3 and a radial length L4, and L3 ═ L1+ (0.8mm to 1.0mm) and L4 ═ n (L2+ (0.25mm to 0.3mm)), so that the thickness of the flat copper wire enamel, the thickness of the insulation paper used, the assembly process and the like are fully considered, the assembly of the corresponding first flat wire 21 in the first parallel groove segment 131 is facilitated, and the flat contact between the first flat wire 21 and the first parallel groove segment 131 is ensured.
In some embodiments, the second flat wires 22 in the second parallel slot segments 132 are provided with m layers, each layer of the second flat wires 22 has a circumferential width of L5 and a radial length of L6, and m × L5 × L6 ═ S-n × L1 × L2, where S is a total area of the flat wire design in a single stator slot, and m is an integer not less than 1, which can increase a slot filling ratio of the stator slot. Specifically, as shown in fig. 1, m is 2. In some embodiments, the second parallel groove segment 132 has a circumferential width of L7 and a radial length of L8, and L7 ═ L5+ (0.8mm to 1.0mm) and L8 ═ m (L6+ (0.25mm to 0.3mm)), which fully considers the thickness of the flat copper wire enamel, the thickness of the insulation paper used, the assembly process, and the like, facilitates the assembly of the corresponding first flat wire 21 in the first parallel groove segment 131, and ensures the flat contact between the first flat wire 21 and the first parallel groove segment 131.
In some embodiments, n and m are even numbers, and the two flat wires at the end of the stator can be combined into two copper wires with equal cross-sectional areas by welding as many as possible.
In some embodiments, each of the stator teeth 12 includes a tooth segment corresponding to each of the parallel slot segments, the circumferential width of one of the tooth segments is L9, the circumferential width of another of the tooth segments is L10, and L9 is (0.9-1) L10, the design of the width and height of each slot segment tends to make the minimum value of the tooth width of each segment approximately equal, the width distribution of the front end and the rear end is more uniform, the problem of locally large magnetic density of the stator tooth body is alleviated, the utilization rate of the iron core material is improved, and the iron loss of the stator is reduced.
