The invention belongs to the technical field of wind driven power generators, and particularly relates to a super-large-specification wind power rotor workpiece, and an intelligent assembly system and an assembly method thereof. The rotor workpiece is of a combined outer rotor structure and comprises a plurality of rotor module units distributed in an annular array, wherein each rotor module unit comprises a mounting block, a non-magnetic heat conduction strip and a permanent magnet block made of a permanent magnet, each mounting block is composed of a magnet yoke plate, an inner arc-shaped shaft sleeve plate, an outer arc-shaped mounting plate, a baffle, a first lug plate and a second lug plate, each magnet yoke plate is of a sector plate structure, the inner end portion of each magnet yoke plate is connected with the corresponding inner arc-shaped shaft sleeve plate, the outer end portion of each magnet yoke plate is connected with the corresponding baffle through the corresponding outer arc-shaped mounting plate, and the two side edges of the magnet yoke plate are respectively provided with a lug plate. The super-large-specification wind power rotor workpiece is of a combined outer rotor structure, and compared with traditional overall transportation, parts can be transported to the coast firstly and then assembled, so that the transportation difficulty is reduced while the transportation cost is also reduced.

Description

technical field [0001] The invention belongs to the technical field of wind power generators, and in particular relates to a super-large wind power rotor workpiece, an intelligent assembly system and an assembly method thereof. Background technique [0002] In recent years, high magnetic energy permanent magnet technology has developed rapidly, especially the rare earth permanent magnet material NdFeB has been widely used in direct drive generators. The direct drive generator using permanent magnet technology has a simple structure and high efficiency. For the outer rotor permanent magnet direct drive wind power generator, the characteristic of the outer rotor motor is that the stator is fixed in the middle of the shaft, and the rotor rotates on the periphery of the stator, which is also a radial air gap magnetic flux structure. Compared with the inner rotor structure The position of the rotor and the stator is changed. The stator is called the inner stator inside the motor...

AI Technical Summary

Problems solved by technology

[0003] However, the existing ultra-large wind power rotor workpieces have shortcomings. First, due to the unreasonable structural design of the rotor workpiece and the limitation of the intelligence of the assembly system, the rotor workpiece can only be pre-assembled and then transported to the coast. The components are transported to the coast for assembly, which not only makes the transportation difficult, but also greatly increases the transportation cost; the second is to install the permanent magnet directly on the rim of the rotor. This structure makes the permanent magnet very close to the stator coil and comes from the stator coil. A large amount of heat will be transferred to the permanent magnet, and the permanent magnet is not conducive to heat dissipation due to its small contact area with the rotor, which will easily affect the magnetic properties of the permanent magnet; the third is to consider reducing the eddy current loss on the rotor. The rim of the rotor Generally, non-magnetic materials are used, but if the rotor is made of non-magnetic materials as a whole, the overall strength cannot be guaranteed.
