Abstract
The invention relates to a double-stator alternating current motor flywheel power accumulator. First high speed bearings are arranged at an upper end shaft and a lower end shaft of a flywheel; the first high speed bearings are respectively supported with an upper intermediate shaft and a lower intermediate shaft; and second high speed bearings are respectively arranged on the upper intermediate shaft and the lower intermediate shaft as well as are used for respectively supporting an upper end surface and a lower end surface at an inner side of a housing. Annular permanent magnet rotors are symmetrically inlaid and fixed at an upper end surface and a lower end surface of the flywheel; and the upper end surfaces and the lower end surfaces of the annular permanent magnet rotors are magnetic poles. The two rotors are opposite for same polarities. Stator cores that are formed by annular ferrites and are corresponded to the corresponded annular permanent magnet rotors are respectively arranged at the upper end surface and the lower end surface at the inner side of the housing. The housing is provided with binding posts that are connected with all stator windings. And all the stator cores, the stator windings and the corresponded rotors respectively form alternating current disc type motors. According to the power accumulator, alternating current disc type motors are used to drive a flywheel, so that a disadvantage of sliding contact of direct current brushes is overcome; and a double high speed bearing cascade structure is employed, so that the flywheel can work at a highest speed that is twice as fast as the speeds of the high speed bearings. Moreover, the power accumulator provided in the invention has an outstanding advantage of simple and reasonable structure.

The basic structure of general flywheel energy storage system by flywheel, utilize the electromagnetic bearing suspending flywheel and be provided with mechanical protection bearing, permanent-magnetic brush-less DC electronic synchronously/generating mutual-inverse type motor, Electric Machine Control and electric power converter, high vacuum and protective cover essential part with certain security performance constitute.The present invention only relates to the accumulator body construction that comprises flywheel, motor, bearing and housing.
In the prior art; The characteristic of a kind of pair of stator disc type acyclic dc electric machine flywheel accumulator is; The inboard upper and lower end face of housing is symmetrically fixed with the stator that is made up of the disc type acyclic dc electric machine inside and outside annular permanent-magnet steel; Stator is respectively equipped with and is symmetrically fixed on flywheel upper and lower end face and the identical disk type rotor of shape up and down, and the rotor coil of two disk type rotors is connected, and the armature spindle of each disk type rotor is supported in the high-speed bearing at housing two ends respectively; Stator constitutes one pole disc type direct current machine with two disk type rotors that are electrically connected up and down, and each high-speed bearing connects lead terminal respectively.
There is following defective in above-mentioned pair of stator disc type acyclic dc electric machine flywheel accumulator: each high-speed bearing is the key link that the direct current machine electric current leads in/out; The disadvantage that has the brush sliding contact equally, brush sliding contact are one of root problems that causes the flywheel energy storage device functional reliability difference that direct current machine drives.
Summary of the invention
There is the technical problem of brush sliding contact in the present invention in order to solve existing two stator disc type acyclic dc electric machine flywheel accumulator, and discloses a kind of pair of stator alternating current machine flywheel accumulator.
The present invention takes following technical scheme for realizing above-mentioned purpose: this flywheel accumulator comprises the housing of sealing; Characteristic is that said flywheel upper and lower side axle is provided with first high-speed bearing, jack shaft about each first high-speed bearing is supported with respectively; Jack shaft is respectively equipped with second high-speed bearing about each; Each second high-speed bearing is supported in the inboard upper and lower end face of housing respectively, and said flywheel upper and lower end face symmetry is inlayed and is fixed with the annular permanent magnet rotor, and annular permanent magnet rotor upper and lower end face is a magnetic pole; Two rotor same polarities are relative; The inboard upper and lower end face of said housing is respectively equipped with and the corresponding stator core that is made up of annular ferrite of respective annular p-m rotor, and housing is provided with the binding post that connects each stator winding, and each stator core and stator winding thereof constitute respectively with rotor accordingly and exchange disc type electric machine.
