Utility model works explanation:
Using two iron cores, two iron cores are located at the upper and lower of motor, and iron core is tray type structure, between two iron cores
PM rotor is installed, convenient for improving the utilization rate of permanent magnet.Iron core single simultaneously includes outer housing and core member, is adopted
It is overlapped together respectively, skeleton is put in outside again after salient pole is using the silicon steel sheet punch forming of very little for fabricated structure
Insulation；Then by the assembly of multiple salient poles on inner support, inner support is circle, after assembling, then in its bottom loads onto pressing plate,
Purpose is to enhance the magnetic inductive capacity of stator；Several persons in last indentation support arm, are snuggly mated to together after assembling.
Since the iron core of single tray type structure uses combined assembly structure, each inter-module assembling is simple, all linked with one another；And
And each component processing method can be used traditional processing method such as punching press, die casting and realize, easy to process and cost control, while after
Continuous coiling link can also simple realization, be convenient for large-scale production.It, can be besides using the tray type structure of two iron cores composition
Single output or bimorph transducer parallel output are selected under different operating conditions, improve the flexibility of motor used and the utilization of permanent magnet
Rate.
Salient pole is T-type structure, the form of punching press is used using silicon steel sheet, multi-disc, which laminates, to be riveted；And then it can be in T-type
Upper skeleton protection is covered on the salient pole of structure.
The salient pole of T-type structure is put on inner support one by one, inner support be silicon steel sheet strike out round multi-disc laminate riveting and
At；
It after the two combines, then is pressed into pressing plate, pressing plate is also that silicon steel sheet strikes out round multi-disc and laminates and rivets；
Inner support and pressing plate, are all made of silicon steel sheet, can it is good enhancing iron core assembly magnetic inductive capacity, Er Qiesan
Kind lamination simple shape can be used relatively simple mould punching and laminate riveting molding, and processing and assembling process are convenient for control,
Convenient for batch production and cost control.
Support arm is then an alumiaum article, it is circular opening structure, not only ensure that the integral strength of stator but also had been convenient for electricity
Machine fan heat；The assembly of three kinds of laminations is pressed into the inner wall of support arm by the excircle orientation of inner support, and several persons combine closely with regard to structure
At single iron core.
The opposite separation of two stators can be independent or works together jointly in the upper and lower end of rotor, two stators, can be with
It is flexibly used under different operating conditions；A stator is only allowed to work when extraneous demand is lesser, it is larger in extraneous demand
When, another stator exports always side by side, enhances output effect.
