Example Embodiment
[0023] Example 1
[0024] Such as figure 1 As shown, a damping ring used for a multi-segment cast aluminum rotor includes an outer aluminum ring and an inner silicon steel ring 22. A cast aluminum through groove 211 is provided on the aluminum ring, and a plurality of cast aluminum through grooves 211 are distributed equidistantly to form a ring structure; a grooved rib 212 is formed in the area between two adjacent cast aluminum through grooves. The plurality of cast aluminum through slots 211 form the same number of slotted ribs 212 as the number of cast aluminum through slots 211 between each other, and the number of slotted ribs 212 is a submultiple of the number of rotor slots.
[0025] Preferably, the cast aluminum through groove 211 has a fan-shaped structure, and a plurality of cast aluminum through grooves are equidistantly distributed to form an annular structure concentric with the center of the damping ring.
[0026] The outer diameter of the damping ring is consistent w...
Example Embodiment
[0027] Example 2
[0028] Such as figure 2 As shown, this embodiment includes two equal lengths of the first rotor core 1 and the second rotor core 3. When laminating, the first rotor core 1 is first laminated, and then the damping ring 2 and the second rotor core 3 are laminated The upper part forms a whole to ensure the dislocation of the slotted rib and the iron core trough body. When casting aluminum, the molten aluminum is injected from the end of the first rotor core 1. When the molten aluminum passes through the interface between the first rotor core 1 and the second rotor core 3, it enters through the fan-shaped cast aluminum channel of the concentric aluminum ring of the damper ring 2. Rotor core 3, after casting, the aluminum liquid fills the fan-shaped cast aluminum trough of the concentric aluminum ring to form a complete aluminum ring, connects the guide bars of each rotor into a whole, and forms a cast aluminum end at the end of the whole Ring 4 can complete the c...
Example Embodiment
[0038] Example 3
[0039] Such as image 3 As shown, this embodiment includes four equal lengths of a first rotor core 1, a second rotor core 3, a third rotor core 5, a fourth rotor core 7, a first damping ring 2, a second damping ring 4, and a third rotor core. Damping ring 6, when stacking, first stack the first rotor core 1 of the rotor, then stack the first damping ring 2 and the second rotor core 3, and then stack the second damping ring 4 and the third rotor core 5 Go up, and finally the third damping ring 6 and the fourth rotor core 7 are superimposed to form a whole to ensure that the slotted ribs and the core trough are arranged in a dislocation. When casting aluminum, the molten aluminum is injected from the end of the first rotor core 1. When the molten aluminum passes through the interface between the first rotor core 1 and the second rotor core 3, it passes through the sector-shaped cast aluminum trough of the concentric aluminum ring of the first damping ring 2 Ent...
