Description
Technical field
It the utility model is related to a kind of rotor structure, more particularly to a kind of permanent magnetic brushless with position sensing function
Outer-rotor structure.
Background technology
In the prior art, in order to determine the real time position of rotor, passed typically by single Angle Position is set
Sensor is realized.Because rotor and angular position pick up are all independent individuals, therefore have that space-consuming is big, coordinates
Precision is low, even installs bad the shortcomings of influenceing to use.And the encoder of general motor is all mounted in shaft end, have a strong impact on
Motor volume, when needing flat structure, structure design is highly difficult.
Utility model content
The utility model is directed to the drawbacks of prior art, there is provided outside a kind of permanent magnetic brushless with position sensing function
Rotor structure.
Permanent magnetic brushless outer-rotor structure described in the utility model with position sensing function, including turn annular in shape
Sub- body, the outer ring of the rotor body are provided with encoder gear；The inner ring of the rotor body is provided with magnet steel.
In permanent magnetic brushless outer-rotor structure described in the utility model with position sensing function, the encoder tooth
Upper strata of the wheel in the short transverse of the outer ring of the rotor body, and it is integrally formed with the rotor body.
In permanent magnetic brushless outer-rotor structure described in the utility model with position sensing function, the magnet steel bag
Include uniform 2P magnet steel along the circumferencial direction of the inner ring of the rotor body；
Wherein, P is number of pole-pairs, and span is the positive integer more than 1.
, only need to be corresponding in permanent magnetic brushless outer-rotor structure described in the utility model with position sensing function
Position installation reading head can is realized to be detected to the position of motor and speed.The structure effectively reduces torque motor
Overall volume, solve the problems, such as outer rotor and position sensing element fit precision difference again, molded simultaneously as being integrally machined
Outer-rotor structure with position sensing function, without outer rotor and position sensing element are carried out into later stage installation again, significantly
Simplify operational sequence.
Brief description of the drawings
Fig. 1 is the schematic diagram of the permanent magnetic brushless outer-rotor structure described in the utility model with position sensing function.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in figure 1, the permanent magnetic brushless outer-rotor structure described in the utility model with position sensing function, bag
Rotor body 1 annular in shape is included, the outer ring of the rotor body 1 is provided with encoder gear 3；The inner ring of the rotor body 1
It is provided with magnet steel 2.In actual applications, only need to opposite position install reading head can realize to the position of motor and
Speed is detected, and greatly facilitates user.
Wherein, the encoder gear 3 is located at the upper strata in the short transverse of the outer ring of the rotor body 1, and its with
The rotor body 1 is integrally formed.I.e. during outer rotor is processed, the outer ring in the short transverse of rotor body 1 is direct
Encoder gear 3 is integrally machined out, can both effectively reduce overall volume, solves the problems, such as fit precision difference again, simultaneously as
Shaping is integrally machined, is installed without the later stage, enormously simplify operational sequence.
In permanent magnetic brushless outer-rotor structure described in the utility model with position sensing function, the magnet steel
2 include 2P magnet steel uniform along the circumferencial direction of the inner ring of the rotor body 1, and (wherein, P is number of pole-pairs, span
For the positive integer more than 1).Illustrated in the present embodiment by taking uniform eight magnet steel as an example, in actual applications, can be as needed
And multiple magnet steel are set.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
