Abstract
The invention discloses a rotor magnetic levitation structure for a double-stator disc motor flywheel energy storage device. A permanent magnet sleeve opposite to a rotor disc is sleeved on a rotor shaft. A permanent magnet embedding ring is arranged in an axle center hole of the rotor disc. An interval is formed between the permanent magnet sleeve and the permanent magnet embedding ring. Magnetic poles of the opposite surfaces of the permanent magnet sleeve and the permanent magnet embedding ring have the same polarity. An annular lug boss is arranged at the central position of the outer circular surface of the rotor disk. A cavity body of a sealing shell is provided with annular bumps which are opposite to the upper and lower surfaces of the annular lug boss respectively. Axially levitated permanent magnet rings are arranged on the upper and lower surfaces of the annular lug boss of the rotor disc and the opposite annular bumps at an equal interval, and magnetic poles of the opposite surfaces of the axially levitated permanent magnet rings have the same polarities. By the rotor magnetic levitation structure, the radial swing or axial endplay of the rotor disc rotating at high speed can be avoided, and the so-called limiting is finished in a non-contact state, so that the problem that the rotor shaft is correspondingly deflected by the swing of the rotor disc and centrifugal force can be completely solved, and an ordinary high-speed bearing also can meet the requirements of the flywheel energy storage device.
Description
Technical field
The invention belongs to the flywheel energy storage device, particularly relate to a kind of pair of stator disc type electric machine flywheel accumulator rotor magnetic suspension structure.
Background technology
The utility model of notification number CN201928127U " two stator alternating current machine flywheel accumulator "; The supporting construction that has comprised a kind of rotor (flywheel) in its disclosed technical scheme; Be that flywheel upper and lower side axle is provided with first high-speed bearing; Each first high-speed bearing is supported with jack shaft up and down respectively, and jack shaft is respectively equipped with second high-speed bearing about each, and each second high-speed bearing is supported in the inboard upper and lower end face of housing respectively.
Above-mentioned utility model is that two stator cores and stator winding thereof constitute respectively with corresponding rotor and exchange disc type electric machine, and rotor is a flywheel accordingly, and it has overcome the disadvantage that two stator disc type acyclic dc electric machine rotor coils need the brush sliding contact effectively.Above-mentioned utility model also adopts two high-speed bearing series arrangement, makes the flywheel can be to double the rotation speed operation of high-speed bearing Maximum speed limit.
Though two high-speed bearing series arrangement of above-mentioned utility model have prolonged the useful life of high-speed bearing relatively, but still can not thoroughly solve the root problem that existing high-speed bearing can not adapt to the specification requirement of flywheel high speed rotating.
Summary of the invention
The present invention can not satisfy the technical problem of flywheel high speed rotating needs in order to solve existing high-speed bearing, and discloses a kind of pair of stator disc type electric machine flywheel accumulator rotor magnetic suspension structure.
The present invention takes following technical scheme for realizing above-mentioned purpose: this rotor magnetic suspension structure comprises armature spindle and the rotor disk of the seal casinghousing that is made up of cavity and two ends end cap, disk rotor, the high-speed bearing at support rotor axle two ends; Characteristic is; Rotor axle sleeve is equipped with and the corresponding permanent magnetism sleeve of rotor disk; The axle center hole of rotor disk is provided with permanent magnetism edge ring; Be provided with at interval between permanent magnetism sleeve and the permanent magnetism edge ring, the pole polarity of its opposite face is identical, and the middle position of said rotor disk periphery is provided with annular boss; The cavity of said seal casinghousing is provided with respectively and the corresponding annular protrusion of annular boss upper and lower surfaces, and said rotor disk annular boss upper and lower surfaces is respectively equipped with pairing annular protrusion that spacing equates and the identical axial suspension permanent-magnetic clamp of pole polarity of opposite face.
The present invention can also take following technical measures:
The remanent magnetism of said each axial suspension permanent-magnetic clamp, magnetic strength coercive force, HCJ are identical with magnetic energy product magnetic property index.
Beneficial effect of the present invention and advantage are: armature spindle permanent magnetism sleeve and rotor disk permanent magnetism edge ring have radially position-limiting action with respect to rotor disk, can avoid radially wobbling of rotor disk.In fact the disc type electric machine stator core just has auxiliary radially position-limiting action to rotor disk.Rotor disk annular boss upper and lower surfaces and the paired axial suspension permanent magnetic ring of pairing cavity annular protrusion have the axial limiting effect for rotor disk, can avoid the axial endplay of rotor disk.It is thus clear that; Rotor magnetic suspension structure of the present invention can be avoided rotor disk when high speed rotating, to produce radially wobbling or axial endplay; And the spacing completion under contactless state of this what is called; Therefore can thoroughly solve the corresponding beat of armature spindle, make general high-speed bearing also can be competent at the requirement of flywheel accumulator because of rotor disk swing and centrifugal force generation.Prototype test shows that the rotor disk of this rotor magnetic suspension structure is that the maximum speed of flywheel can reach 85,000r/min, and the 24h that turns round continuously, employed general high-speed bearing does not have wear phenomenon.The present invention also is applicable to the supercentrifuge that nuclear energy is used.The present invention has simple in structure, practical outstanding advantage.
