Abstract

The utility model discloses a switch magnetic resistance motor. The switch magnetic resistance motor comprises a stator structure, a rotation shaft, and a rotor connected with the rotation shaft. The stator structure is integrally of a sealing structure and comprises a stator core, a winding encircling the periphery of the stator core, a housing covering the stator core and a connection cylinder connected with the housing to form a sealing chamber. The stator core and the winding are surrounded by the sealing chamber, and an evaporation liquid coolant which generates a damping effect force for the vibration of the stator core and the winding is packaged in the sealing chamber. By employing such a structure, since the stator core is the main part which emits the vibration and noise, and the stator core is immersed in an insulation liquid, the liquid forms great friction resistance for any motion trend of a stator, accordingly, the vibration of the stator is attenuated in a damping mode, and besides, the spreading of sound can also be prevented. Therefore, the vibration reduction and noise reduction effects are obvious.

Please refer to Fig. 2, the schematic diagram of the seal stator structure of a kind of embodiment that Fig. 2 is switched reluctance machines that the utility model provides.

In a kind of embodiment, as shown in Figure 2, the utility model provides a kind of switched reluctance machines, and this motor comprises stator structure, rotating shaft 8, the rotor 7 being connected with rotating shaft 8.Stator structure integral body is hermetically-sealed construction, comprise stator core 1, be surrounded on stator core 1 periphery winding 2, cover in the housing 3 outside stator core 1, and be connected to form the connecting cylinder 4 of annular seal space with housing 3, stator core 1 and winding 2 are surrounded in annular seal space, are packaged with the evaporative cooling liquid 6 to the generation of vibration damping action power of described stator core 1 and winding 2 in annular seal space.

What produce due to above-mentioned switched reluctance machines is the electromagnetic force wave of pulsation, and when the tooth of stator core 1 is relative with the groove of rotor 7, this Radial magnetic force is minimum, when the tooth of stator core 1 is relative with the tooth of rotor 7, and this Radial magnetic force maximum.And stator is shell structure, unavoidably, because being subject to the vibration of the compression of radial pulsation magnetic attraction effect generation systematicness, expansion, this vibration is by the outside shot noise of casing, so stator structure is the main contributor of switched reluctance machines noise.

Adopt after said structure, because evaporative cooling liquid is low boiling, high insulation, incombustible evaporative cooling liquid 6, during motor operation, winding 2, stator core 1, and other structure member is because various losses produce amount of heat, making to be filled in its evaporative cooling liquid 6 temperature around raises, until reach the saturation temperature of the liquid medium corresponding with pressure in cavity, come to life, and then heat absorption vaporization, be gas, liquid two-phase state, heat generating components is sufficiently cooled, again because the temperature of the working medium of seething with excitement during boiling heat transfer is distributed near saturation temperature point substantially, each stator department position Temperature Distribution that medium is soaked is more even, especially stator end is without local hot spot.The steam cooling fluid of gas, liquid two-phase state, its density is less than liquid medium, produce buoyancy and upwards buoyance lift run into the condenser 9 at top, heat is passed to and is condensed into liquid after the condensed water in it and drops back to again original place, realized like this self-loopa under normal temperature, noiseless evaporative cooling.

The most important thing is, because stator core is the critical piece that sends vibration and noise, and stator core is immersed in the middle of the liquid of insulation, by magnetic field analysis, obtain the distribution situation of electromagnetic force, then the vibration of carrying out in stator total is calculated, this is carried out to brief analysis by electromechanical analogy method, can obtain

The vibration velocity of stator core and motor case is:

$\stackrel{\→}{Y}=\frac{P_n{e}^{{\mathrm{j\φ}}_n}}{(r_{m1}+r_{m2})+j[\mathrm{\ω}(m_1+m_2)-\frac{1}{\mathrm{\ω}}(K_1+K_2)]}---\left(1\right)$

The amplitude of vibration displacement is:

$Y=\frac{1}{\mathrm{\ω}}\·\frac{p_n}{\sqrt{{(r_{m1}+r_{m2})}^2+{[\mathrm{\ω}(m_1+m_2)-(K_1+K_2)/]\mathrm{\ω}}^2}}---\left(2\right)$

In formula: p _nfor equivalent concentrated force, r _m1, r _m2be respectively viscous damping coefficient unshakable in one's determination and casing, ω is angle of throw frequency, K ₁, K ₂respectively rigidity unshakable in one's determination and casing, m ₁, m ₂it is respectively quality unshakable in one's determination and casing.

Evaporative cooling medium soaks after whole stator, has greatly increased the viscous damping coefficient r in formula (1) and formula (2) _m1with r _m2, be equivalent to significantly reduce vibration velocity and vibration amplitude, facts have proved when the specified working capacity 2500KW of motor, noise, less than 100db, surpasses 20% than the reducing noise of the asynchronous machine of conventional structure of the same type.Moreover, this motor adopts after immersion type evaporative cooling stator mode, because cooling effect is best, motor volume reduces 1/3rd than conventional structure of the same type, and power output also significantly improves, thereby realizes the utility model target of low-vibration noise.

As can be seen here, adopt after said stator hermetically-sealed construction, evaporative cooling liquid is on cooling basis, can form great frictional resistance to any movement tendency of stator, also with regard to the vibration of damping vibration attenuation stator, also can stop in addition the propagation of sound, so vibration damping, noise reduction are obvious.

In the first concrete scheme, as shown in Figure 3 and Figure 4, Fig. 3, Fig. 4 are respectively main pseudosection, the side cutaway view of sealing drum in Fig. 2, above-mentioned connecting cylinder 4 can be cylinder type, described connecting cylinder 4 integral body are located between described rotor 7 and described stator core 1, and the axial two ends of described connecting cylinder 4 are connected with described housing 3.

Please refer to Fig. 5 and Fig. 6, the schematic diagram of the seal stator structure that Fig. 5 is switched reluctance machines that the utility model provides; Fig. 6 is the viewgraph of cross-section of seal stator structure shown in Fig. 5.

In the second concrete scheme, as shown in Figure 5 and Figure 6, above-mentioned connecting cylinder 4 axially connects described stator core 1 and described housing 3, described winding 2 and described housing 3, and described connecting cylinder 4 is sealed described winding 2 from inner side, the inwall of described annular seal space 5 comprises the inwall of described stator core 1 and the inwall of described connecting cylinder 4.

Adopt this structure, axial space between axial space, winding 2 and housing 3 between connecting cylinder 4 connecting stator iron cores 1 and housing 3, and the inwall of annular seal space 5 comprises the inwall of stator core 1 and the inwall of connecting cylinder 4, therefore, the inwall of stator core 1 does not have encapsulated, makes the inwall of stator core 1 as a part for the inwall of annular seal space 5.Compare with the first concrete scheme, the gap between the inwall of stator core 1 and rotor 7 outer surfaces does not have occupied, still can keep less gap (being conventionally no more than 0.4mm) between the inner surface of stator core 1 and the outer surface of rotor 7.Hence one can see that, and this seal stator structure can play the effect of vibration damping, noise reduction, can avoid again the increase of leakage field, guarantees the job stability of switched reluctance machines.
