Abstract
The invention discloses model airplane high-speed motor rare earth magnetic steel with the low manufacturing cost. The model airplane high-speed motor rare earth magnetic steel comprises a rare earth material (SmCo5) layer. A Cr protective layer is arranged on the surface of the rare earth material (SmCo5) layer. The model airplane high-speed motor rare earth magnetic steel has the advantages that high residual magnetization is improved, magnetic flux consistency is good, high temperature resistance and corrosion resistance are achieved, and the size of the model airplane high-speed motor rare earth magnetic steel on a model airplane high-speed motor rotor is smaller, so that the sizes of components like a shell are smaller, energy consumption, electricity consumption and the using cost are reduced, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of model plane high-speed electric expreess locomotive, relate in particular to a kind of model plane high speed rotor of motor rare earth magnetic steel.
Background technology
China is rare earth resources big country, and rare earth storage capacity accounts for 80% of world's total amount, along with the improving constantly and develop of scientific and technical innovation dynamics, especially the demand of rare earth permanent-magnetic material goods is grown with each passing day.Should see, analyze with regard to the development trend of China's present stage: the one, the exploitation ability of resource is little, according to authoritative department statistics, still has 30% rare earth resources to fail to be developed comprehensive utilization to China in 2010; The 2nd, just current manufacturing enterprise of China, the properties of product of exploitation are low, and suitable application area is wideless, also not reaching international advanced standard aspect the key technologies such as magnetic energy product and remanent magnetism, polarity deviation, resource has been caused to certain waste especially; The 3rd, domestic enterprise's scale is less, and the quality of product is uneven, and performance is stable not, and the capability and performance index of most products rests on the level of the nineties in last century, widens gradually with world-class gap; The 4th, along with the continuous emergence of the industries such as auto manufacturing, advanced audio, navigation, medical treatment, communication, be badly in need of high performance rare earth permanent magnet product, because domestic production enterprise cannot meet its demand, have to rely on a large amount of imported products, waste national a large amount of foreign exchange and affected the paces that relevant industries march to high-end product market.
In addition, the permanent magnet array comprising in the rotor of model plane high-speed electric expreess locomotive, magnetic field is provided in air gap, utilize electromagnetic induction effect to produce induced electromotive force at stator winding two ends, therefore permanent magnet is the critical component of high-speed electric expreess locomotive, and its performance is determining work done, overall dimension and the operational reliability of motor.The rotor of existing model plane high-speed electric expreess locomotive be adopt ferrite or aluminium nickel cobalt as induced field, volume is large, causes the parts such as casing also will expand, energy consumption is higher, power consumption is larger, use cost is large, useful life is short.
Summary of the invention
Technical problem to be solved by this invention is: the model plane high-speed electric expreess locomotive rare earth magnetic steel that a kind of low cost of manufacture is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: model plane high-speed electric expreess locomotive rare earth magnetic steel, comprising: rare earth material (SmCo5) layer, is provided with Cr protective layer on the surface of described rare earth material (SmCo5) layer.
In order to solve the problems of the technologies described above better, the further technical scheme that the present invention adopts is: between described rare earth material (SmCo5) layer and Cr protective layer, be provided with silicon layer.
Advantage of the present invention is: above-mentioned model plane high-speed electric expreess locomotive rare earth magnetic steel, improve the high remanent magnetism of product, magnetic flux high conformity, high temperature resistant, corrosion-resistant, less in model plane high speed rotor of motor upper volume, thus cause the piece volumes such as casing less, reduce energy consumption, power consumption and use cost, increased useful life.
Brief description of the drawings
Fig. 1 is the sectional structure schematic diagram of model plane high-speed electric expreess locomotive rare earth magnetic steel of the present invention.
In figure: 1, rare earth material (SmCo5) layer, 2, Cr protective layer, 3, silicon layer.
Embodiment
Describe in detail particular content of the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, model plane high-speed electric expreess locomotive rare earth magnetic steel, comprising: rare earth material (SmCo5) layer 1, is provided with Cr protective layer 2 on the surface of described rare earth material (SmCo5) layer 1.
In the present embodiment, between described rare earth material (SmCo5) layer 1 and Cr protective layer 2, be provided with silicon layer 3.
Above-mentioned model plane high-speed electric expreess locomotive rare earth magnetic steel, the high remanent magnetism of raising product, magnetic flux high conformity, high temperature resistant, corrosion-resistant, less in model plane high speed rotor of motor upper volume, thereby cause the piece volumes such as casing less, reduced energy consumption, power consumption and use cost, increased useful life.
