Description
Technical field
The present invention relates to technical field of motors, relate in particular to a kind of stator structure of switched reluctance machines.
Background technology
Electric automobile is to make with the complete petroleum replacing class A fuel A of electric power the automobile driving, at environmental protection, the aspect such as clean, energy-conservation in occupation of absolute advantage.The drive motors of electric automobile mainly contains direct current machine, asynchronous machine, permanent magnetic brushless and switched reluctance machines etc.Switched reluctance machines becomes the strong competitor of each drive system with advantages such as simple in structure, cost is low, the ability that is suitable for is strong, speed-regulating range widths.
As shown in Figure 1, this figure is the structure principle chart of switched reluctance machines in prior art.When the control switch SI of A phase winding 2 ' electric current and S2 are when closed, A switches on mutually, B phase, C phase no power simultaneously, A phase excitation produces magnetic field, because the magnetic flux of motor is always along the path closure of magnetic resistance minimum, and in the time of the axis of A phase magnetic pole and the dead in line of rotor 7 ' magnetic pole a the magnetic resistance minimum of magnetic circuit, therefore the distortion magnetic line of force has produced tangential pulling force, attempt to make a-a' to overlap with A-A', finally rotate to the position that a-a' overlaps with A-A' and stop operating.If will make subsequently motor rotate continuously, just need to make B switch on mutually, A phase and the power-off of C phase simultaneously, now the magnetic field in motor has become the magnetic field take B phase magnetic pole as axis, and rotor 7 ' meeting continues rotation until overlap completely with B-B'.Switch on mutually to subsequently C, A phase and the power-off of B phase simultaneously, now the magnetic field in motor has become the magnetic field take C phase magnetic pole as axis, and rotor 7 ' meeting continues rotation until overlap completely with C-C'.So iterative cycles, as long as threephase stator winding 2 ' press A-B-C-A ... order switch on successively, the rotor 7 of motor ' will be around the shaft 8 ' center line rotation in the same direction always.
Can be found out by the above-mentioned course of work, the electromagnetic torque that switched reluctance machines produces is stable unlike the electromagnetic torque of traditional AC and DC motor, but pulsation character, corresponding magnetic pull not only has tangential, also have radially, what wherein pull motor rotation is the tangential component of magnetic pull, because of its pulsation character, cause motor to move steadily, produce deformation and vibration, and then produce serious noise.The radial component of magnetic pull can change along with rotor 7 ' position and stator winding 2 ' electric current, caused thus motor stator core 1 ' deformation and vibration, and then produced again more serious noise.
For the problems referred to above, as shown in Figure 2, develop gradually transpiration-cooled technology.This technology is that whole stator is sealed in a cavity completely, inject in this cavity low boiling, high insulation, incombustible evaporative cooling liquid 6 '.When 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.
Because stator is the critical piece that sends vibration and noise, and stator is immersed in the middle of the liquid of insulation, this liquid forms great frictional resistance to any movement tendency of stator, also with regard to the vibration of damping vibration attenuation stator, also can stop the propagation of sound in addition, therefore vibration damping, noise reduction are obvious.
As shown in Figure 2, above-mentioned evaporation cooling technique be with a sleeve 4 ' be close to stator core 1 ' inner surface, this sleeve 4 ' the housing 3 ' be connected of two ends and switched reluctance machines, by stator entirety cooling needs (comprise all stator cores 1 ' with winding 2 ') be all surrounded, form a seal chamber, then in seal chamber, inject evaporative cooling liquid 6 ', so that evaporative cooling liquid 6 ' to stator core 1 ' and winding 2 ' soaked.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, the cylindrical integral sleeve 4 of this sleeve 4 ' be both ends open ', so, stator and rotor 7 ' between space (being referred to as " air gap " in Electrical Motor) must sufficiently largely can put down this sleeve 4 ' (General Requirements air gap is at least wanted 3mm), and this structural principle is not suitable for switched reluctance machines.Because, switched reluctance machines be utilize rotor 7 ' main flux (also can be described as magnetic resistance) rate of change produce the electromagnetic torque of drive motors rotation, if air gap is excessive, can cause main flux and main flux rate of change reduce and leakage flux increases, thereby weakening driving torque, the increase that also can bring noise.
In view of this, urgently for above-mentioned technical problem, seal stator structure to switched reluctance machines of the prior art is done further optimal design, make it can eliminate vibration and noise that stator core produces, can not take again the air gap between stator and rotor, thereby avoid the increase of leakage field, strengthen the job stability of switched reluctance machines.
