Abstract
The invention discloses a tangential magnetic steel permanent magnet motor rotor which comprises a rotating shaft, magnetic poles and magnetic steel, wherein the rotating shaft is uniformly provided with odd pairs of magnetic poles, a magnetic steel groove is arranged between every two adjacent magnetic poles, the magnetic steel is arranged in each magnetic steel groove; and the magnetic poles are fixed on the rotating shaft through fixed bolts. According to the invention, a tangential magnetic steel rotor structure is adopted, solid magnetic poles are adopted as the magnetic poles, and the rotating shaft is made of a non-magnetic-conduction material, the solid magnetic poles and the rotating shaft are fixed by bolts, and the magnetic poles are fixed together at two end parts of the magnetic poles by adopting stainless steel bushes so that the magnetic poles bear a huge eccentric force. The a tangential magnetic steel permanent magnet motor rotor has the characteristics of simple structure, convenience for assembly, and capability of bearing the huge eccentric force, and is especially suitable for a high-power high-speed permanent magnetic power generator.
Description
Technical field:
The invention belongs to machine field, relate to a kind of tangential set magnet permanent rotor, especially a kind ofly solid magnetic pole is fixed on the tangential set magnet permanent rotor in the rotating shaft through set bolt.
Background technology:
Along with deepening continuously of regenerative resource researchs such as wind power generation, the high-speed permanent magnetic synchronous generator will become a desirable type.The rotor magnetic steel structural shape comprises: tangential, radial, hybrid.Consider the structural shape of high-speed permanent magnetic synchronous generator; Root diameter is relatively still bigger, and rotating ratio is higher, arrives 1600rpm sometimes; Even higher rotating speed; Condition lower rotor part magnet steel produces huge centrifugal force like this, needs rotor core can bear such centrifugal force, therefore selects for use tangential magnet steel rotor structure can finely bear such centrifugal force.Existing tangential magnet steel structure, as shown in Figure 1, need non-magnetic conduction sleeve in its permanent magnet rotor structure, reduce the leakage field of rotating shaft side permanent magnet, the complex structure of rotor, assembly difficulty is bigger.
Summary of the invention:
The technical problem that the present invention solves is, provides a kind of and can bear the huge centrifugal force of magnet steel, simplifies rotor structure, reduced the permanent magnet rotor structure of rotor assembly difficulty.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of tangential set magnet permanent rotor is provided, said tangential set magnet permanent rotor comprises rotating shaft, magnetic pole and magnet steel; Said rotating shaft evenly is provided with the even-even magnetic pole, is provided with the magnet steel groove between the adjacent pole, in the magnet steel groove magnet steel is set; Said magnetic pole is fixed in the rotating shaft through set bolt.
