Abstract
The utility model provides a biconvex utmost point brushless DC generator, include the fore -stock, with fore -stock complex after -poppet, be fixed in the fore -stock with inboard stator chip subassembly, the cover of after -poppet is located the rotor chip subassembly at stator chip subassembly center, with the rotor shaft of the integrative fixing of rotor chip subassembly and install in excitation winding and armature winding on the stator chip subassembly. This application is changeed from establishhing simple structure, low in manufacturing cost.
Description
Technical field
The application relates to electrical generator fields, particularly relates to a kind of brushless DC electric generator with dual salient poles.
Background technology
Normally, stator is coiling to current alternator for vehicle structure, and rotor is pawl pole excitation rotor, and rotor excitation coil carries out conducting by collector ring and carbon brush CONTACT WITH FRICTION.Complex structure, number of spare parts is many, and manufacturing process is loaded down with trivial details, and manufacturing cost is higher.
Utility model content
The embodiment of the present application provides a kind of brushless DC electric generator with dual salient poles, in order to solve the problem that prior art rotor assembly spare part is too much, manufacture complexity.
The embodiment of the present application adopts following technical proposals:
A kind of brushless DC electric generator with dual salient poles, comprises fore-stock, the after-poppet coordinated with described fore-stock, is fixed on stator chip assembly inside described fore-stock and described after-poppet, is sheathed on the rotor core chip module at described stator chip assembly center, and the described rotor core chip module integrally armature spindle of fixing and the excitation winding be installed on described stator chip assembly and armature winding.
Described rotor core chip module is silicon steel sheet material.
Described armature spindle and silicon steel sheet directly laminate and form described rotor core chip module.
Compared to prior art, the application is by being flush-mounted on line layer by photo-biological genetic chip, again line layer is covered on support, then lens jacket, inner sheet are overlying on the inner side of described line layer in order to just to face, solve the problem without phototherapy instrumentation in prior art.And verified by many experiments, be just optimum distance to the distance of the face mask structure of face distance face with 10-20mm.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present application, and form a application's part, the schematic description and description of the application, for explaining the application, does not form the improper restriction to the application.
Fig. 1 is the cross section view of a kind of brushless DC electric generator with dual salient poles of the application.
Embodiment
For making the object of the application, technical scheme and advantage clearly, below in conjunction with the application's specific embodiment and corresponding accompanying drawing, technical scheme is clearly and completely described.Obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
Below in conjunction with accompanying drawing, describe the technical scheme that each embodiment of the application provides in detail.
Refer to shown in Fig. 1, a kind of brushless DC electric generator with dual salient poles of the application comprise fore-stock 1, the after-poppet 7 coordinated with described fore-stock 1, be fixed on stator chip assembly 3 inside described fore-stock 1 and described after-poppet 7, be sheathed on the rotor core chip module 5 at described stator chip assembly 3 center, with the armature spindle 6 of described rotor core chip module 5 one fixing and the excitation winding 2 be installed on described stator chip assembly 3 and armature winding 4.
Described armature spindle 6 directly forms integral rotor assembly with rotor core chip module 5 through press-fiting, and described rotor core chip module 5 is silicon steel structure.Namely described armature spindle 6 directly laminates with silicon steel sheet and forms described rotor core chip module 5.
The application, based on ordinary tap reluctance motor, described stator chip assembly 3 increases excitation winding 2, and realizes the size conversion of magnetic flux by controlling described excitation winding 2.And described integral rotor assembly is directly overrided to form by armature spindle 6 and silicon steel sheet, described silicon steel sheet forms described rotor core chip module 5, need to turn the technical scheme of installing collector ring and carbon brush on setting up in entirety compared to prior art, the application's brushless DC electric generator with dual salient poles overall structure is simple, and number of spare parts is few, adopts brushless control, mechanical rubs, efficiency is high, good reliability, substantially prolongs the useful life of product simultaneously.High temperature when being applicable to automobilism, reliability service at a high speed, under the adverse circumstances such as vibrations.
Set up magnetic field after excitation winding 2 energising of the application, when described rotor core chip module 5 rotates, the magnetic linkage of stator winding linkage changes, thus induces electromotive force; When load or rotation speed change, by regulating the size of current of described excitation winding 2 to keep the constant of output voltage.
The foregoing is only the embodiment of the application, be not limited to the application.To those skilled in the art, the application can have various modifications and variations.Any amendment done within all spirit in the application and principle, equivalent replacement, improvement etc., within the right that all should be included in the application.
