Abstract
The utility model discloses a rare earth permanent magnet synchronous generator rotor of a permanent magnet synchronous generator, which comprises a rotating shaft, a rotor iron core sheet, a separating magnet end plate and a rare earth magnetic steel. The separating magnet end plate leans against the end of the iron core sheet and is supported on the rotating shaft together with the iron core sheet. The rare earth magnetic steel is embedded in the rotor iron core sheet with a folding shaped distribution. The rare earth magnetic steel separates the iron core sheet into three parts which are one middle part and two pole arc parts. A plurality of separating magnet bridges which are parallel to the magnetic field axial line are arranged on the two pole arc parts of the iron core sheet. The leaking magnetic flux of the utility model is small and the effect of the intersection axis magnetic field to the straight axis magnetic field is small and the utility model is convenient to be assembled.
Description
Technical field
The utility model relates to a kind of magneto alternator, especially relevant its excitation rotor.
Background technology
The rare earth permanent magnet synchronous generator can be supporting with various dissimilar dynamic power machines, forms portable power source, is widely used in communication, digs up mine, builds the road, the stand-by power supply of forestry, military affairs, car and boat and enterprises and institutions.Existing rare earth permanent magnet synchronous generator rotor be inlaid with plate shaped rare earth magnetic steel in the groove of its rotor core laminate patch, and the rotor core laminate patch is an overall structure, so leakage flux is bigger; And in when assembling, plate shaped rare earth magnetic steel need be from axially the inlaying of rotor, and assembling is trouble; In addition since every magnetic bridge less and irrational distribution, so quadrature axis armature reaction magnetic field is bigger to the influence in d-axis magnetic field.
Summary of the invention
The purpose of this utility model is to provide a kind of leakage flux less, is convenient to assembling, and hands over the axle magnetic field rare earth permanent magnet synchronous generator rotor less to the influence in d-axis magnetic field.
In order to achieve the above object, the technical solution of the utility model is: a kind of rare earth permanent magnet synchronous generator rotor, comprise rotating shaft, the rotor core laminate patch, every magnetic end plate and rare earth magnetic steel, every the end of magnetic end plate against the rotor core laminate patch, and be supported in the rotating shaft with the rotor core laminate patch, rare earth magnetic steel is embedded among the rotor core laminate patch, being folding shape distributes, rare earth magnetic steel is divided into three parts with the rotor core laminate patch, be mid portion and two polar arc parts, partly have with the magnetic field axis line parallel some every magnetic bridge at two polar arcs of rotor core laminate patch, on the magnetic end plate, having and the above-mentioned through hole that connects every magnetic bridge.
After adopting said structure, because rare earth magnetic steel is divided into three parts with the rotor core laminate patch, i.e. mid portion and two polar arc parts, therefore, that has cancelled rotor core laminate patch both sides is subjected to the magnetic cross section, and when increasing the rotor core laminate patch on the whole and be subjected to the magnetic cross section, leakage flux greatly lowers; Also owing to partly have with the magnetic field axis line parallel some every magnetic bridge at two polar arcs of rotor core laminate patch, these do not have obstruction every the d-axis magnetic field that magnetic bridge is set up rare earth magnetic steel, and there is iris action in quadrature axis armature reaction magnetic field, quadrature axis armature reaction magnetic field is reduced to minimum to the influence in d-axis magnetic field.In addition, and in when assembling, rare earth magnetic steel can be convenient to assembling from tangentially the inlaying of rotor core laminate patch.

Embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
As Fig. 1,2,3,4,6,7, shown in 8, rare earth permanent magnet synchronous generator rotor of the present utility model, comprise rotating shaft 1, rotor core laminate patch 4, every magnetic end plate 3 and rare earth magnetic steel 6, every the end of magnetic end plate 3 against rotor core laminate patch 4, and be supported in the rotating shaft 1 with rotor core laminate patch 4, rare earth magnetic steel 6 is embedded among the rotor core laminate patch 4, being folding shape distributes, rare earth magnetic steel 6 is divided into three parts with rotor core laminate patch 4, be mid portion 4-1 and two polar arc part 4-2, have with the magnetic field axis line parallel some every magnetic bridge 4-3 at two polar arc part 4-2 of rotor core laminate patch 4, on magnetic end plate 3, having and the above-mentioned through hole 3-1 that connects every magnetic bridge 4-3.
Shown in Fig. 5,3, rare earth magnetic steel 6 is plate shaped, and rare earth magnetic steel 6 is two pairs of basic symmetries in rotor core laminate patch 4 two foldings distribute.Also can adopt three foldings or many foldings to distribute.
Shown in Fig. 1,2,3,4,8, for the ease of more rotor core laminate patch 4 is axially fastened the location, and make rare earth magnetic steel 6 in place more firm, rotor core laminate patch 4 axially by being separated into two parts at least, every magnetic end plate 3, rotor core laminate patch 4 and fixing in aggregates by rivet 2 together every magnetic partition 5 every magnetic end plate 3 with every magnetic partition 5.Adopt the benefit of rivet 2 connections to be, rotor core laminate patch 4 is difficult for loosening, and the heating loss is little.
As shown in Figure 6, the end face 4-2-1 of two polar arc part 4-2 of rotor core laminate patch 4 is non-concentric circle arc plane, and these two nonconcentric(al) end face 4-2-1 can constitute non-homogeneous air gap with circle in the stator of generator.Like this, just can further improve the air-gap field waveform and reduce quadrature axis armature reaction magnetic field.
