Abstract
The invention discloses a high-efficiency switch reluctance machine, and the machine comprises a rotor shaft, rotor laminations, a rotor lining, a coding disc, and a coding disc lining. The rotor shaft passes through the rotor lining and the rotor lining is disposed at the central part of the rotor shaft. Inner sides of two ends of the rotor lining are respectively provided with the rotor laminations. One end of the rotor shaft is provided with the coding disc, and the coding disc is provided with a gap. The coding disc lining is disposed in the gap of the coding disc. An insulating part is disposed between a rotor iron core and a rotating shaft. The insulating part is disposed between the rotor iron core and the rotating shaft, thereby achieving a better insulating effect between the rotor iron core and the rotating shaft. The rotating shaft cannot generate static when the motor operates, and an operator cannot be shocked electrically in a use process even if the operator touches the rotating shaft, thereby improving the safety of the machine.
Description
Technical field
The present invention relates to machine field, specifically a kind of high efficiency switched reluctance motor.
Background technology
Switched reluctance machines is a kind of novel buncher, and governing system has direct current concurrently, exchanges the advantage of two class governing systems, is the latest generation stepless time adjustment system of frequency conversion speed-adjusting system, Speed Regulating System of Brushless DC Motor of continuing.Its structure simple rigid, speed-regulating range width, speed adjusting performance is excellent, and all has greater efficiency in whole speed adjustable range, and system reliability is high.
Your switched reluctance machines of producer in the market, its structure comprises armature spindle, rotor pack and non-magnetic partition, wherein rotor pack is permeability magnetic material, non-magnetic partition is circular metal material, when rotor rotates, non-magnetic partition by recessed for rotor extremely in eddy current separate, can reach to a certain extent and reduce windage, the object of raising the efficiency, but the employing of non-magnetic partition inevitably increases the physical dimension of whole rotor-support-foundation system, and rotor still exists windage.
Summary of the invention
The present invention aims to provide a kind of practical high efficiency switched reluctance motor.
For realizing described object, the invention provides following technical scheme: a kind of high efficiency switched reluctance motor, comprising armature spindle, rotor pack, rotor bushing, coding disk and coding disk lining; Rotor bushing is arranged on the middle part of armature spindle through armature spindle, and be provided with rotor pack inside the two ends of rotor bushing, one end of armature spindle is provided with coding disk, and coding disk is provided with gap, and coding disk lining is filled in the gap on coding disk; Insulating part is provided with between rotor core and rotating shaft.
Compared with prior art, the invention has the beneficial effects as follows: this high efficiency switched reluctance motor, by arranging insulating part between rotating shaft and rotor core, make that there is between rotor core and rotating shaft good insulation effect, motor operation course shaft can not produce electrostatic, even if operating personnel in use touch the danger that rotating shaft also can not occur to get an electric shock, improve the security performance of electric switch reluctance motor.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-5, in the embodiment of the present invention, a kind of high efficiency switched reluctance motor, comprises armature spindle 1, rotor pack 2, rotor bushing 4, coding disk and coding disk lining 6; Rotor bushing 4 is arranged on the middle part of armature spindle 1 through armature spindle 1, and be provided with rotor pack 2 inside the two ends of rotor bushing 4, one end of armature spindle 1 is provided with coding disk 5, and coding disk 5 is provided with gap, and coding disk lining 6 is filled in the gap on coding disk 5.
Be bright and clean periphery outside described rotor bushing 4, inner side and rotor tooth mating part adopt thin-wall construction, and general monolateral wall thickness is 0.1-0.5mm, this is done to ensure there is less air gap between rotor and stator.And position adopts comparatively thick structure between two rotor tooths, monolateral thickness is determined according to rotor tooth depth, can ensure that the structural strength of rotor bushing 4 is as the criterion.Rotor bushing 4 coordinates with adopting interference mode between rotor tooth.During installation, will the rotor bushing 4 of certain Excircle machining surplus be had to heat rear press-in rotor pack 2, ensure the good contact of rotor pack 2 each several part and rotor bushing 4.The object done like this is that the heat in order to enable rotor pack 2 operationally produce is a part of to external radiation by rotor bushing 4.Finally adopt grinding machine to process rotor bushing 4 cylindrical assembled, reach the object reducing air gap on the one hand, windage during working rotor can be reduced on the other hand.Rotor bushing 4 can adopt the non-magnet material such as stainless steel, aluminium alloy to make.
Insulating part is provided with between rotor core and rotating shaft, by arranging insulating part between rotor core and rotating shaft, improve the insulation property of switched reluctance machines, not charged in switched reluctance machines rotating shaft, conform to the requirement of II class instrument, improve the security performance of switched reluctance machines, expand the range of application of switched reluctance machines.
Coding disk 5 is rotating parts of switch magnetoresistance motor rotor position transducer, and the rotor number of teeth of coding disk 5 is consistent with number of teeth of motor rotor and with rotor synchronous rotary.It inevitably stirs surrounding air generation aerodynamic noise and even screams in the process of running.In order to avoid the generation of this situation, adopt and with the nonmetallic materials 6 of coding disk 5 equal thickness, volume coding disk inter-lobe clearance is filled.Requirement after filling is the axis of coding disk external member and radial impulse-free robustness, and plane is smooth.
This embodiment operationally can obviously reduce its running noise, eliminates rotor windage.When motor runs up, its efficiency improves, the motor of same dimensional parameters, and rotating speed is higher, and improved efficiency is more obvious.
To those skilled in the art, obviously the invention is not restricted to the details of described one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of described explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
