Description
Technical field
The utility model belongs to electromechanical equipment technical field, is specifically related to a kind of asymmetric tooth magnetoresistance transformer.
Background technology
In the Alternating Current Governor System with high dynamic performance, the strategy such as vector controlled, Direct Torque Control is extensively adopted
With, and obtaining motor rotor position angle information is the basic premise realizing these control strategies.Rotary transformer is substantially one
Planting signal electric machine, for other sensors, it has reliable operation, durable, axial length is short and motor bucket axle is installed
Etc. advantage, therefore apply more in the fields such as AC servo.
The current rotary transformer stator number of teeth is mostly more, when being applied to small space, and minute sized rotary transformer
Stator winding is extremely difficult, and very poor in the reliability of the occasions such as frequent strenuous vibration, and because adjacent teeth spacing is less, manual
Rolling off the production line very difficult and winding being dispersed greatly, precision is difficult to ensure, exports in winding induced potential simultaneously and comprises stationary component, no
Easily eliminate.
Utility model content
For overcoming above-mentioned prior art defect, the purpose of this utility model is to provide a kind of stator number of teeth few, it is simple to fixed
Sub-coiling, can be applied to the novel magnetoresistance transformer of small space, can effectively eliminate output winding sensing simultaneously
The stationary component comprising in electromotive force.
For realizing above-mentioned technical purpose, technical solution adopted in the utility model is as follows:
A kind of Novel rotary transformer, including be arranged at the rotor core of main shaft periphery, and is arranged at described rotor iron
The stator core of heart periphery, is provided with air gap between described rotor core and stator core, it is characterised in that: described rotor core
Outer rim is provided with salient pole, and described stator core is provided with double wedge in inner circumferential, and described stator core is provided with at double wedge and comprises
Excitation winding and the winding element of output winding, described double wedge is provided with 4, and the mechanical angle between adjacent tooth is 67.5 °,
Also include the compensation double wedge being arranged on described stator core inner circumferential, be provided with at described compensation double wedge sinusoidal compensate around
Group and cosine compensative winding.
Further, it is preferred that, described double wedge and compensation double wedge are configured to parallel teeth, and described increment is shaped as and rotates
The concentric circular arc in center.
Further, it is preferred that, described compensation double wedge is respectively 67.5 ° and 90 ° with the angle of adjacent tooth.
Further, it is preferred that, in described rotor core, salient pole is provided with 4.
Further, it is preferred that, described gas length is 1.0～1.6mm.
Further, it is preferred that, described convex tooth width is 4.0～4.5mm, the height of described compensation double wedge is 2.2～
2.6mm。
By above technical scheme, the utility model has the few feature of the stator number of teeth, it is simple to stator winding, can be preferable
Be applied to small space, compensate double wedge by adding simultaneously, and be not provided with on double wedge encouraging winding, Neng Gouyou because compensating
Effect eliminates the stationary component comprising in output winding induced potential.
Brief description
Fig. 1 is the utility model structural representation.
Detailed description of the invention
For making creation means of the present utility model, technical characteristic and operation principle it can be readily appreciated that below in conjunction with accompanying drawing and reality
Execute example to be described in further details the utility model, but be not construed as to restriction of the present utility model.
As it is shown in figure 1, a kind of Novel rotary transformer provided by the utility model, including be arranged at main shaft 1 periphery
Rotor core 2, and it is arranged at the stator core 3 of described rotor core 2 periphery, between described rotor core 2 and stator core 3
Being provided with the air gap 4 of 1.3mm, described rotor core 2 outer rim is provided with 4 salient poles 5, and described stator core 3 is arranged in inner circumferential
Having 4 double wedges 6, described stator core 3 is provided with the winding element comprising to encourage winding 7 and output winding 8, phase at double wedge 6
Mechanical angle between adjacent double wedge 6 is 67.5 °, also includes the compensation double wedge 9 being arranged on described stator core 3 inner circumferential,
At described compensation double wedge 9, forward seals in sinusoidal compensative winding 10 and cosine compensative winding 11 respectively.
As preferred embodiment of the present utility model, described double wedge 6 and compensation double wedge 9 are configured to parallel teeth, and its facewidth is
4.2mm, end be shaped as the circular arc concentric with pivot, the height of described double wedge is 2.2～2.6mm, and its with adjacent
Double wedge 6 between angle be respectively 67.5 ° and 90 °.
During work, utilize the saliency of rotor core 2, along with the rotation of rotary transformer, be arranged at stator core 3
On in winding element the inductance of output winding 8 also change therewith, thus induce and there is rotor core 2 positional information
Electromotive force；Meanwhile, it is on compensation double wedge 9 not encourage winding 7 with the difference of remaining four tooth because compensating double wedge 9, owing to magnetic flux is total
Being to close along the maximum path of magnetic conductance, compensating air gap 4 magnetic flux under double wedge 9 very little, sinusoidal compensative winding 10 and cosine compensate
Winding 11 is only because compensating flux change in double wedge 9 and induced potential, and its magnetic flux is zero with the magnetic flux algebraical sum in remaining four tooth, energy
Enough effectively elimination exports the stationary component comprising in winding 8 induced potential.
Of the present utility model general principle, principal character and of the present utility model advantage, one's own profession have more than been shown and described
Skilled person will appreciate that of industry, the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Principle of the present utility model is simply described, on the premise of without departing from the utility model spirit and scope, the utility model is also
Have various changes and modifications, in the range of these changes and improvements both fall within claimed the utility model.The utility model
Claimed scope is defined by appending claims and equivalent thereof.
