Abstract
The utility model discloses a brushless motor of external structure of hall board, include: stator assembly, rotor assembly, rear end cap, hall board subassembly and response magnetic ring, the rotor set assembling is on the motor shaft, and the stator set assembling is outside the rotor assembly, and the rear end cap assembles in stator assembly one end, and hall board subassembly is fixed on the rear end cap, and the response magnetic ring is fixed in the motor shaft one end of extending the rear end cap. In this way, the utility model discloses outside can guaranteeing motor normal function, reduce the size of the electric machine the smooth easy and heat dissipation of motor inner space. The response magnetic ring is external with hall board subassembly, and hall element keeps away from the armature field, and the reduction armature field improves the electric efficiency to hall element's influence.
Description
Technical field
The utility model relates to machine field, particularly relates to a kind of brushless electric machine of Hall Plate external structure.
Background technology
At present, can be used for the electric tool class high-speed high-power motor that high pressure and degree of protection are higher, complete machine space is the smaller the better, requires the volume of motor also will diminish thereupon thereupon.
Motor internal size has also had definite value after power of motor is set thereupon. And how to save motor internal space, and make full use of complete machine space, do not changing in power of motor and function situation, guarantee motor is normally worked, and is the anxious technical issues that need to address.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of brushless electric machine of Hall Plate external structure, can, outside guarantee motor normal function, motor volume be dwindled, and motor internal space fluency is easy to heat radiation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the brushless electric machine that a kind of Hall Plate external structure is provided, comprise: field frame assembly, rotor assembly, rear end cap, Hall Plate assembly and reaction magnetic ring, rotor assembly is assemblied on motor shaft, field frame assembly is assemblied in outside rotor assembly, rear end cap is assemblied in field frame assembly one end, and Hall Plate assembly is fixed on rear end cap, and reaction magnetic ring is fixed on the motor shaft one end of extending rear end cap.
In preferred embodiment of the utility model, also comprise drive end bearing bracket, drive end bearing bracket and rear end cap by screw fastening on field frame assembly.
In preferred embodiment of the utility model, Hall Plate assembly is fixed by screws on rear end cap.
In preferred embodiment of the utility model, described reaction magnetic ring is by flat filament shape mating holes and motor shaft one end assembly connection.
The beneficial effects of the utility model are: the utility model outside motor normal function, dwindles motor volume ensureing, motor internal space fluency easily with heat radiation. Reaction magnetic ring and Hall Plate assembly are external, and Hall element, away from armature field, reduces the impact of armature field on Hall element, improves electric efficiency.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of brushless electric machine one preferred embodiment of the utility model Hall Plate external structure;
Fig. 2 is the installation diagram of the brushless electric machine of the external structure of Hall Plate shown in Fig. 1.
Detailed description of the invention
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
A brushless electric machine for Hall Plate external structure, comprising: field frame assembly 1, rotor assembly 2, rear end cap 3, Hall Plate assembly 4 and reaction magnetic ring 5.
Rotor assembly 2 is assemblied on motor shaft 6, and field frame assembly 1 is assemblied in outside rotor assembly 2, and rear end cap 3 is assemblied in field frame assembly 1 one end, and Hall Plate assembly 4 is fixed by screws on rear end cap 3, and reaction magnetic ring 5 is fixed on motor shaft 6 one end of extending rear end cap 3.
The utility model is preferred, and described reaction magnetic ring 5 is by flat filament shape mating holes and motor shaft 6 one end assembly connections.
Compact conformation of the present utility model, volume is little, and maintenance is convenient. Hall element, away from armature body, reduces the impact of armature field.
Also comprise drive end bearing bracket, drive end bearing bracket and rear end cap 3 by screw fastening on field frame assembly 1. This motor is integral type motor, and rear end cap 3, rotor assembly 2, field frame assembly 1, leading portion lid all use screw fastening.
The utility model outside motor normal function, dwindles motor volume ensureing, motor internal space fluency easily with heat radiation. Reaction magnetic ring and Hall Plate assembly are external, and Hall element, away from armature field, reduces the impact of armature field on Hall element, improves electric efficiency.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
