Description
Technical field
The present invention relates to machine field, especially a kind of protection type HALBACH permanent-magnetic synchronous motor rotor.
Background technology
Present existing wind-driven generator, the above wind-driven generator of particularly large-scale MW level exists heaviness.Complex structure, the cost height, existing especially wind-powered electricity generation magneto alternator, it is immature to exist rotor structure, be to set firmly conventional radial magnetizing permanent magnetism body piece by S at rotor surface, the N alternating polarity distributes and installs, and some directly is installed in the rotor cylindrical with glue, establishes the hole in addition in permanent magnet blocks, use bolt, have after fluting on the steel plate is put magnet to be installed on the rotor, be designed to internal rotor wind-force synchronous generator, exist with low content of technology, the reliability low performance descends, when useless worker was useless, the production cycle was longer, and none can reach many shortcomings such as practical value structure topsy-turvy in a word.
Summary of the invention
It is low that purpose of the present invention just provides a kind of cost, technology maturation, simple in structure, in light weight, reliable operation, a kind of permanent-magnetic synchronous motor rotor of energy-conservation and long service life is the another great technological progress of internal rotor permanent magnet synchronous machine, can replace existing magneto industry fully, the wind-powered electricity generation industry, the technical barrier that technology is not mature enough for building green energy resource, has been established solid foundation.
1. the objective of the invention is to realize by such technical scheme, a kind of protection type HALBACH permanent-magnetic synchronous motor rotor, hollow magnetic conduction rotor HALBACH magnet structure is arranged, the rotor field spider and the fan blade that connect firmly rotating shaft constitute, in hollow magnetic conduction rotor inner concentric the HALBACH magnet structure is set, be hollow magnetic conduction rotor from inside to outside magnetic conduction HALBACH is provided external magnetic field, described hollow magnetic conduction rotor has magnet isolation tank, described hollow magnetic conduction rotor is supported by rotor field spider by shank of bolt and both ends of the surface by the bolt hole, be combined into and hide HALBACH magnet structure rotor, it is the inner rotor motor rotor that is concentric with the anti-centrifugal type HALBACH magnet structure in the hollow magnetic conduction rotor that described some permanent magnet bars are combined as tubular, outer-rotor type protection external magnetic field rotor.
The present invention compares with existing permanent-magnetic synchronous motor rotor, cost is extremely low, avoid conventional design unreasonable, performance declines to a great extent, and the out-put supply quality is low, can not reach the requirement of sinusoidal wave emf phase waveform, and it is minimum that inserted tooth changes the hard iron pulsation, even stator need not advantages such as skewed slot and effectively replaces prior art cost height, and the permanent magnetic material utilance is low, the cost height, technology is loaded down with trivial details, loss is big, and efficient is low, and structure is immature, reliability is low fragile, defective such as can't promote, bring the beyond thought technique effect of people, huge economic benefit and social benefit are arranged.
Description of drawings
Description of drawings of the present invention is as follows
Fig. 1 is the hollow rotor structure for permanent magnet motor schematic diagrams of 4 HALBACH of 4 extremely every utmost points
Fig. 2 is the hollow rotor structure for permanent magnet motor schematic diagrams of 4 HALBACH of 8 extremely every utmost points
Among the figure: 1, hollow magnetic conduction rotor 2, HALBACH magnet structure 3, bolt hole 4, casting are equipped with rail 5 admittedly, annotate aluminum 6, stator
Embodiment
Below in conjunction with drawings and Examples the present invention is done a nearly step explanation.Fig. 1 is the hollow rotor structure for permanent magnet motor figure of the present invention, figure hollow core magnetic conduction rotor (1) is to laminate formation with the good soft magnetism steel plate punching of magnetic property, and in magnet isolation tank, annotate aluminium and fix, being convenient to the construction bolt bar also can directly be fixed on the hollow magnetic conduction rotor (1) with annotating the aluminium method, the HALBACH magnet structure, by designing requirement give be loaded on after magnetizing hollow magnetic conduction rotor inboard by polarity respectively by dress, the rotor field spider that connects firmly rotating shaft is made as that circle cooperates the concentric installation of assurance in its cylindrical of convex shaft coupling plate and the magnetic conduction rotor.One end is that dead fixedly interference fit is on main shaft, other end shaft coupling plate also can be arranged to taper for its axis hole of convex and be convenient to dismounting, on the two shaft coupling plates even have ventilation hole and therein an end fan is set, fully giving permanent magnetic material provides heat radiation to stablize the motor runnability, motor is never demagnetized, improving the plurality of advantages such as useful life of motor greatly, is the wind-powered electricity generation industry, one of magneto industry optimal way.If send out to obtain the design people's permission required in this invention but look on the bright side of things, also can not be broken claim scope of the present invention, any execution mode is not limited.
