Abstract
The present invention has the rotary transformer of double-winding structure, comprising: yoke portion, the yoke portion are ring-type；Teeth portion, the teeth portion is evenly distributed in the circumferential direction on the inside of the yoke portion, forms tooth socket between the adjacent guide tooth；Main winding, the main winding are arranged in the tooth socket；Redundancy winding, the redundancy winding are arranged in the tooth socket, and the main winding is relative to the redundancy winding closer to the lower layer of the tooth socket.Compared with prior art, the present invention has the shortcomings that the rotary transformer of double-winding structure has the advantage that 1) present invention needs to replace immediately after solving irredundant rotation accident barrier, improves the reliability of system significantly；2) main winding that change is revolved in the present invention is high with the consistency of redundancy winding；3) production method of the present invention is easy, and with the covert ratio of irredundant rotation, increased cost is less.
Description
Technical field
The present invention relates to sensor fields, more particularly to improve the double redundancy processing scheme of sensor reliability, especially
It is a kind of rotary transformer with double-winding structure.
Background technique
Rotary transformer is a kind of accurate sensor for transmitting angle, speed signal, mainly applies to various servo-systems,
The measurement of angle and speed and the occasion of sensing are needed, such as: in industrial servo and New-energy electric vehicle.Mainly apply to need
In the measurement and sensing for wanting angle and speed, angle (revolving speed) signal is provided for controller.The reliability of rotary transformer and anti-
Interference is very high, is widely used.But is there are abnormal conditions, generating the dismounting since bump injury or solder joint fall off when leading to broken string
It is inconvenient or when not allowing, can not can be removably mounted, occur as soon as the requirement for needing redundancy backup.In order to further improve the reliability, at present
Common means are the safeguard measures increased to winding, and increase the Detection & Controling of butt welding point mass, but often cost is big
And effect is unobvious.
Summary of the invention
In view of the above technical problems, there is double winding knot the object of the present invention is to provide a kind of solution above-mentioned technical problem
The rotary transformer of structure.
In order to solve the above technical problems, the present invention has the rotary transformer of double-winding structure, comprising: yoke portion, the yoke
Portion is ring-type；Teeth portion, the teeth portion is evenly distributed in the circumferential direction on the inside of the yoke portion, the shape between the adjacent guide tooth
At tooth socket；Main winding, the main winding are arranged in the tooth socket；Redundancy winding, the redundancy winding are arranged in the tooth socket
Interior, the main winding is relative to the redundancy winding closer to the lower layer of the tooth socket.
Preferably, the teeth portion is silicon steel teeth portion.
Preferably, main winding lead-out wire one end is connect with the main winding, redundancy winding leading-out wire one end with
The redundancy winding connection.
Preferably, the main winding lead-out wire draws out of different the tooth socket respectively from the redundancy winding leading-out wire
Out.
Compared with prior art, there is the present invention rotary transformer of double-winding structure to have the advantage that
1) present invention needs to replace immediately after solving the disadvantage that irredundant rotation accident barrier, and improve system significantly can
By property；
2) main winding that change is revolved in the present invention is high with the consistency of redundancy winding；
3) production method of the present invention is easy, and with the covert ratio of irredundant rotation, increased cost is less.
Detailed description of the invention

Specific embodiment
The present invention is described in further detail below, and the explanation of the invention is not limited.It ties below
Attached drawing is closed to make further instructions the present invention.
As shown in FIG. 1 to 3, the present invention has the rotary transformer of double-winding structure, the uniform cloth on the inner wall in yoke portion 1
Teeth portion 2 is set, conduct magnetic field is used for.Since product size limits, space is limited in the tooth socket between teeth portion 2, it is therefore desirable to select
Thinner enameled wire, at the same consider offline convenience, here use 0.1mm line footpath enameled wire, by it is bifilar and around
Mode while coiling main winding 3 and redundancy winding 4.It is standby to have done redundancy for the excitation winding to rotation change and output winding herein
Part.In order to avoid short circuit between two groups of windings, the mode for eliminating conventional two groups of coils of every phase winding coiling here and welding,
14 winding formers have been made, the process welded between group is eliminated, have reduced the probability of short circuit, breakdown.Meanwhile in order to avoid lead
With the short circuit at enameled wire bonding wire, and in order to avoid two groups of winding leading-out wires (main winding lead-out wire 5 and redundancy winding leading-out wire
6) cause to obscure when using, the lead-out wire of two groups of windings is drawn from two slots relatively far apart respectively.
After finished product is made, test for the rotary transformer of the double-winding structure, it should be noted that equal to two groups of windings
It is tested, whether qualified verifies its precision, output voltage.Wherein when testing one group of winding, another set winding
It must make open circuit processing.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or modify within the scope of the claims, this not shadow
Ring substantive content of the invention.In the absence of conflict, the feature in embodiments herein and embodiment can any phase
Mutually combination.
