Abstract
The utility model discloses a switch reluctance motor comprising a housing, a rotor, and a stator. The stator and the rotor respectively adopt a salient pole structure. The stator is fixedly disposed on the housing, and the rotor is movably disposed on the housing. The housing adopts a cylindrical hollow structure, two ends of which are respectively provided with a disc-shaped end cover. The outer side of the housing is provided with the outer housing, and a cooling chamber can be formed between the outer housing and the housing, and is disposed around the outer side of the housing in an encircled manner. The surface circulating oil cooling structure of the switch reluctance motor has advantages of small oil way resistance and good cooling effect. By adopting the switch reluctance motor, the heat dissipation problem of the large power switch reluctance motor can be solved, and the power density of the motor can be greatly improved.
Description
Technical field
The utility model relates to a kind of switched reluctance machines.
Background technology
Along with the development of technology, much equipment all requires its drive motors to possess the performances such as high starting torque, high-speed cruising, the interior speed governing of broad range.The current basic dependence on import of driving motor in high-end field of textile machinery, main extraordinary variable-frequency motor or the servomotor of using, price is very high, be unfavorable for promoting on a large scale and technological improvement, and switched reluctance machines has the good characteristics such as simple in structure, cost is low, control is flexible, fault-tolerant ability is high, its overload capacity is strong simultaneously, starting current is little, frequently rotating, good energy-conserving effect, so switched reluctance machines starts be applied to need four quadrant running governing system and realize in broad velocity interval in the system of high-efficiency operation at present.Switched reluctance machines is when realizing high-output power density, and the unit volume loss producing during motor operation significantly increases, and causes that motor each several part temperature raises.Electric machine temperature rise is too high or local temperature rise is too high, can have influence on the fail safe of generating equipment, when serious, can make insulating material accelerated ageing, material insulation property sharply reduces, and significantly shortens the useful life of motor, even causes motor to catch fire, personnel's Danger Electric shock risk, causes great economic loss.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of strong switched reluctance machines of cooling effect with the cooling mode of surperficial recycle oil.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this switched reluctance machines comprises housing, rotor, stator, described rotor, stator are all salient-pole structure, described stator is fixedly mounted on housing, and described rotor is movably arranged on housing, and described housing is cylinder type hollow structure, two ends are provided with discoid end cap, described outside is provided with shell, between described shell and housing, forms cooling chamber, and described cooling chamber is looped around outside.Cooling chamber indoor moveable has cold oil, and cold oil is communicated with the heat that just switched reluctance machines can be produced and passes fast with exterior line, thereby reaches cooling effect.Cooling chamber covers outside, can also have larger area of dissipation, has extended the useful life of equipment, is specially adapted to high speed rapier loom.
For the rotor of realizing switched reluctance machines in the most direct mode transmission of power the main shaft to loom, as of the present utility model preferably, described rotor is integral type structure.The rotor of motor and gear, on an axle, can make main shaft obtain enough moment within the extremely short time like this, allow driving the first latitude beat up effectively, eliminate bad start-up; And can, in the utmost point accurately braking in the short time, eliminate the parking trace of cloth cover.
For ease of the angle position between manual adjustments rotor and stator, as of the present utility model preferred, described rotor is provided with the hexagon-headed bolt of manual adjustments.
As of the present utility model preferred, the end cap of described housing one end is provided with encoder and terminal box.After switched reluctance machines matching coding device and outside controller, can effectively reduce torque ripple and improve the rotating speed of motor.
The utility model adopts technique scheme: the oil circuit resistance of the cooling structure of surperficial recycle oil of switched reluctance machines is little, good cooling results.Thoroughly solve the heat dissipation problem of high power switch reluctance motor, greatly improved the power density of motor.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described in detail.
Fig. 1 is the structural representation of the utility model switched reluctance machines.
Embodiment
As shown in Figure 1, this switched reluctance machines comprises housing 1, rotor 2, stator, rotor 2, stator are all salient-pole structure, stator is fixedly mounted on housing 1, rotor 2 is integral type structure, rotor 2 is movably arranged on housing 1, described housing 1 is cylinder type hollow structure, two ends are provided with discoid end cap, the end cap of housing 1 one end is provided with encoder 5 and terminal box, encoder 5 is fixedly connected with one end of rotor, and the signal output part of encoder 5 is connected with terminal box, and terminal box is connected with external control circuit; Housing 1 outside is provided with shell 3, and shell 3 is tightly connected by mode and the housing 1 of interference fit, between shell 3 and housing 1, forms cooling chamber 4, and cooling chamber 4 is looped around housing 1 outside.Shell 3 is provided with two through holes for being connected with outside cooling line.The cold oil that flowing in cooling line, cold oil is entered and is distributed in after cooling chamber 4 around housing 1 by pipeline, and the heat producing during rapidly by work is taken housing 1 out of, and then plays effective cooling effect.In order to promote the convenience of this switched reluctance machines, rotor 2 is provided with the hexagon-headed bolt 5 of manual adjustments, can directly adjust fast by manual type like this when needs are adjusted.
