Description
Technical field
The invention belongs to dynamo-electric field, be specifically related to the bilateral normal direction electromagnetic actuator of a kind of high-performance and brake or compressor.
Background technology
The electromagnetic actuator such as electromagnet, YE has been widely used in all trades and professions. taking electromagnet as example, existing electromagnet mainly contains electric excitation and two kinds of structures of composite excitation, the former is fixed core and moving iron core with magnet exciting coil, and the latter also posts permanent magnet and realize the composite excitation of permanent magnetism, electric excitation on the fixed core with magnet exciting coil or moving iron core. electricity excitation structure is the simplest, but electromagnetic force need overcome whole load force, it is larger to maintain electric current, the advantage of composite excitation is after electromagnetic actuation that permanent magnetic attraction helps to overcome a part of load force, maintain electric current and reduces, but also brings the new problems such as equivalent working gas gap increase, operating current sharp increase. composite excitation structure mainly contains two kinds of hidden pole type and salient pole types. salient pole type structure as shown in Figure 1, (direction of magnetization longitudinally or radially at least one permanent magnet, point to the noseiron of both sides) be clipped between two blocks of noseirons, the direction of magnetization of adjacent permanent magnet is contrary, on noseiron, collect and form N, the noseiron utmost point that S replaces and the setting of fixed core matched in clearance, magnet exciting coil operated by rotary motion is on fixed core, non-working-gap one side of this structural requirement noseiron utmost point is non-magnetic yoke portion and to require enough thickness or do not establish yoke portion be enough thickness air sections, make permanent magnetic field (magnetic line of force) Main Current to fixed core one side, but unavoidably still have quite a few permanent magnetic field, energy (can reach more than 30%) drains to non-magnetic yoke portion or outer air and has suffered, although salient pole type leakage field is large, permanent magnet can not make full use of, but magnetic field easily saturated feature makes the permanent magnetic field that its forms, the comparable non-salient pole structure of suction is strong, but yoke portion is the feature of non-magnet material or air (because magnetic resistance is difficult to very greatly form electric excitation path), and to have determined that it installs exciting current and output power that magnet exciting coil need to provide additional very large, cause electromagnet volume large, cost is high. for hidden pole type structure, as shown in Figure 2, yoke portion is that magnetic conduction iron yoke is so that as a magnetic flux path part, N, the permanent magnet (direction of magnetization is along normal direction air gap direction) of S alternative arrangement sticks on magnetic conduction iron yoke and the setting of fixed core matched in clearance, magnet exciting coil is arranged on fixed core or is arranged on permanent magnet magnetic conduction iron yoke behind and is used for producing electric exciting field, this structure permanent magnetic field leakage field is little, but because permanent magnet can be regarded the hollow coil of energising as, effective air gap is large, the magnetic field that it forms is difficult for saturated, magnetic field is not strong, electromagnetic attraction is generally little compared with salient pole, permanent magnet thickness (along normal direction air gap direction) is for electric magnetic excitation circuit, can regard air-gap as, can cause very large magnetic resistance and magnetic pressure to fall, making electric excitation magnetic potential (being the product of exciting current and coil turn) major part be depleted to permanent magnet equivalence air-gap has suffered, be equivalent to working gas gap and increased several times, therefore the exciting current that it need to provide and output power are also very large, coil easily generates heat, also cause electromagnet volume very large, cost is high, generally only working gas gap can be used for very little, the occasion of permanent magnet very thin thickness, for most application scenarios, be difficult to meet instructions for use. in addition, above-mentioned electromagnet is used in large impulse stroke (large working gas gap), the heavily loaded fields such as brake as opening (declutching) power source, in order to overcome the heavy load power such as very large tripping spring power, also there is electromagnetic actuation electric current excessive (can reach and maintain tens times of electric current even decades of times), maintain the inherent shortcomings such as electric current is large, volume is excessive, become the bottleneck problem of its engineering application of restriction.

Fig. 4 is the structure principle chart of the magnetic level with magnet exciting coil, and magnet exciting coil is arranged on the iron core in magnetic level. Fig. 5, Fig. 6, Fig. 7 are column type magnetic level structure, are made up of at least one group of iron core being radially arranged alternately and magnet, and the action principle of Fig. 4, Fig. 5, Fig. 6, Fig. 7 is similar to the above.
Described magnet is monolithic magnet or one group of magnet, or identical or not identical polylith magnet forms by polarity, as with yoke portion or the halbach magnet array with yoke portion not. Magnet is the magnetic materials such as permanent magnet, electric excitation body, superconducting magnet, determines according to concrete needs. In general the strong magnetic permanent-magnet that, preferentially adopts NdFeB material to make.
According to above-mentioned principle, make electromagnet, electromagnetic actuator and deadman's brake and suit somebody to a T. Magnetic level or armature are connected with friction catch mechanism brake block or brake arm, drive without external force, only depend on and itself pass into steady closure or the opening function that little electric current just can be controlled the increase gradually of normal direction gap, normal force or reduce gradually to realize electromagnetic actuator or brake.
