Benefits of technology

The technical effect of this innovation was that it introduced an improved version of a dual high-axle (HAL) motors called Double High Axles®(HDAs), allowing vehicles equipped with these HA's to have better performance at higher speeds without adding extra weight or reducing their efficiency. This technology could help make cars smarter by improving fuel economy while also being able to handle more powerful engines like gasoline pistons.

Problems solved by technology

This patented describes different technical features related to an improved motor system called AXL Disc Motion (Axial Magnet Synchronous Motor). These improvements aimed at reducing unwanted vibrations caused by high levels of current flowing through certain parts inside these systems while still maintaining good performance. However, there may be other factors such as improving control over the rotating part or increasing its size without compromising on its ability to produce enough energy from available electricity sources like batteries.

Embodiment

[0016] This embodiment involves a double-high axial motor that can effectively reduce back electromotive force torque ripple, such as Figure 1 to Figure 7 As shown, the motor includes a segmented armature 1, a rotor disk 2, a bearing pressure plate 3, an iron core 4, and a stator bar 5. It is characterized in that the iron core 4 of the segmented armature 1 is separated by an axial motor The bearing pressure plate 3 fixes the bearing on the stator, the segmented armature 1 uses wire rods to fix the iron core, and connects to the outer motor casing, the iron core 4 uses soft magnetic composite materials, and according to the number of poles in turn Design the curved surface, set the radian to be small or not set if it is closer to the incoming line end, set a suitable arc for the farther from the incoming line end, increase the saliency rate, and reduce the influence of inter-electrode resistance on the back electromotive force. Iron core 4 uses The stator bar 5 is fixed, and the
