Description
本発明は、レゾルバステータ構造に関し、特に、端子ピンの数よりもたるみ穴の数を多くすることにより、１本のたるみピンには１本のみの端線が接するようにするための新規な改良に関する。 The present invention relates to a resolver stator structure, and more particularly, a novel improvement for allowing only one end line to contact one slack pin by increasing the number of slack holes rather than the number of terminal pins. About.
従来、用いられていたこの種のレゾルバステータ構造としては、例えば、図２に示される特許文献１の構成を挙げることができる。
すなわち、図３において符号１で示されるものは、所定角度間隔で内方へ向けて突出する複数の突出磁極２を有する輪状ステータであり、前記各突出磁極２には、前記輪状ステータ１の各端面に一体又は別体にて形成された輪状絶縁カバー４を介して周知のステータ巻線３が巻回されている。
As this type of resolver stator structure conventionally used, for example, the configuration of Patent Document 1 shown in FIG. 2 can be cited.
That is, what is denoted by reference numeral 1 in FIG. 3 is a ring-shaped stator having a plurality of projecting magnetic poles 2 projecting inward at predetermined angular intervals, and each projecting magnetic pole 2 includes each of the ring-shaped stator 1. A well-known stator winding 3 is wound through a ring-shaped insulating cover 4 formed integrally or separately on the end face.
前記輪状絶縁カバー４の一部には、前記輪状ステータ１の外側へ向けて突出する端子ピン保持部５が形成され、前記端子ピン保持部５には、図４で示される５個のたるみ用穴７及び６個の端子ピン６が設けられている。
前記各ステータ巻線３の端線３ａは、前記たるみ用穴７内に着脱自在に挿入されているたるみ用ピン８の周面８ａの約半分を介して前記端子ピン６にからげられている。
A part of the ring-shaped insulating cover 4 is formed with a terminal pin holding part 5 that protrudes toward the outside of the ring-shaped stator 1, and the terminal pin holding part 5 has five slacks shown in FIG. A hole 7 and six terminal pins 6 are provided.
An end line 3 a of each stator winding 3 is tangled to the terminal pin 6 through about a half of the peripheral surface 8 a of the slack pin 8 that is detachably inserted into the slack hole 7. .
従来のレゾルバステータ構造は、以上のように構成されていたため、次のような課題が存在していた。
すなわち、端子ピン６の数よりもたるみ用穴７の数が少ないため、図３の一部を拡大して示す図４のように、１個のたるみ用ピン８の周面８ａに対して２本の端線３ａが接した後に、各端子ピン６にからげられているため、各端線３ａ同士が１本のたるみ用ピン８でクロスすることになり、たるみ用ピン８を除去後に各端線３ａ同士のクロス状態が発生し、検出信号の信頼性低下の原因となっていた。
また、輪状ステータ１の内側に設けるロータの形状を変更することによって、軸倍角を１ｘからｎｘまで任意に変えることができるが、例えば、１ｘ以外の軸倍角とし、巻線分布が複雑化した場合には、端子ピン６よりも少ない数のたるみ用ピン８では、たるみをつけることができない端線３ａも発生して浮線の発生となり、振動による断線の恐れも存在していた。
Since the conventional resolver stator structure is configured as described above, the following problems exist.
That is, since the number of the slack holes 7 is smaller than the number of the terminal pins 6, the number of the slack holes 7 is 2 with respect to the peripheral surface 8 a of one slack pin 8 as shown in FIG. Since the end wires 3a are tangled to the terminal pins 6 after contacting each other, the end wires 3a are crossed by one slack pin 8, and each slack pin 8 is removed after each slack pin 8 is removed. A cross state between the end lines 3a occurs, which causes a decrease in the reliability of the detection signal.
In addition, by changing the shape of the rotor provided inside the ring-shaped stator 1, the shaft multiplication angle can be arbitrarily changed from 1x to nx. For example, when a shaft distribution other than 1x is used and the winding distribution is complicated In the case where the number of slack pins 8 is smaller than that of the terminal pins 6, end lines 3 a that cannot be slack are also generated to generate floating lines, and there is a risk of disconnection due to vibration.
本発明は、以上のような課題を解決するためになされたもので、特に、端子ピンの数よりもたるみ用穴の数を多くすることにより、１本のたるみ用ピンには１本のみの端線が接するようにしたレゾルバステータ構造を提供することを目的とする。 The present invention has been made to solve the above-described problems, and in particular, by increasing the number of slack holes rather than the number of terminal pins, only one slack pin is provided. It is an object of the present invention to provide a resolver stator structure in which end lines are in contact with each other.
本発明によるレゾルバステータ構造は、所定角度間隔毎に内方へ向けて突出する複数の突出磁極を有する輪状ステータと、前記輪状ステータに設けられた輪状絶縁カバーを介して前記各突出磁極に巻回されたステータ巻線と、前記輪状絶縁カバーの一端に一体形成され前記輪状ステータの外側へ突出する端子ピン保持部と、前記端子ピン保持部に設けられた複数のたるみ用穴及び複数の端子ピンと、を備え、前記たるみ用穴にたるみ用ピンが設けられている状態下で、前記突出磁極に巻回されている前記ステータ巻線の端線が前記たるみ用ピンを介して前記端子ピンにからげられるように構成したレゾルバステータ構造において、前記たるみ用穴の数は、前記端子ピンの数よりも多い構成であり、また、前記各たるみ用ピンに接触している前記端線の線数は、1本のみとした構成であり、また、前記たるみ用ピンの除去後の前記たるみ線は、自由状態あるいは接着剤による前記端子保持部への接着状態とした構成である。 The resolver stator structure according to the present invention is wound around each protruding magnetic pole via a ring-shaped stator having a plurality of protruding magnetic poles protruding inward at predetermined angular intervals, and a ring-shaped insulating cover provided on the ring-shaped stator. A stator winding, a terminal pin holding portion integrally formed at one end of the ring-shaped insulating cover and projecting to the outside of the ring-shaped stator, a plurality of slack holes and a plurality of terminal pins provided in the terminal pin holding portion, And an end line of the stator winding wound around the projecting magnetic pole is connected to the terminal pin through the sagging pin in a state where the sagging pin is provided in the sagging hole. In the resolver stator structure configured to be bent, the number of the slack holes is larger than the number of the terminal pins, and before the slack pins are in contact with each slack pin. The number of end lines is configured to be only one, and the slack line after removal of the slack pins is configured to be in a free state or an adhesive state to the terminal holding portion with an adhesive. .
本発明によるレゾルバステータ構造は、以上のように構成されているため、次のような効果を得ることができる。
すなわち、所定角度間隔毎に内方へ向けて突出する複数の突出磁極を有する輪状ステータと、前記輪状ステータに設けられた輪状絶縁カバーを介して前記各突出磁極に巻回されたステータ巻線と、前記輪状絶縁カバーの一端に一体形成され前記輪状ステータの外側へ突出する端子ピン保持部と、前記端子ピン保持部に設けられた複数のたるみ用穴及び複数の端子ピンと、を備え、前記たるみ用穴にたるみ用ピンが設けられている状態下で、前記突出磁極に巻回されている前記ステータ巻線の端線が前記たるみ用ピンを介して前記端子ピンにからげられるように構成したレゾルバステータ構造において、前記たるみ用穴の数は、前記端子ピンの数よりも多いことにより、全ての端線にたるみを形成し、かつ、互いにクロスさせることもないため、レゾルバの信頼性を大幅に向上させ、かつ、軸倍角の変更による巻線分布の変更にも対応できる。
前記各たるみ用ピンに接触している前記端線の線数は、1本のみであることにより、各端線のクロスの恐れもなく、高い信頼性を得ることができる。
前記たるみ用ピンの除去後の前記たるみ線は、自由状態あるいは接着剤による前記端子保持部への接着状態であることにより、端線の安全性を確保でき、レゾルバの信頼性の確保を得ることができる。
Since the resolver stator structure according to the present invention is configured as described above, the following effects can be obtained.
That is, a ring-shaped stator having a plurality of projecting magnetic poles projecting inward at predetermined angular intervals, and a stator winding wound around each projecting magnetic pole via a ring-shaped insulating cover provided on the ring-shaped stator A terminal pin holding part integrally formed at one end of the ring-shaped insulating cover and projecting to the outside of the ring-shaped stator, and a plurality of slack holes and a plurality of terminal pins provided in the terminal pin holding part. An end line of the stator winding wound around the projecting magnetic pole is configured to be tangled to the terminal pin through the sagging pin in a state where the sagging pin is provided in the working hole. In the resolver stator structure, since the number of the slack holes is larger than the number of the terminal pins, slack is formed in all end lines and does not cross each other. Resolver greatly improves the reliability of, and can cope with change of the winding distribution of a change in shaft angle multiplier.
Since the number of the end lines in contact with the slack pins is only one, high reliability can be obtained without the risk of crossing the end lines.
The sagging wire after removal of the sagging pin is in a free state or an adhesive state to the terminal holding portion by an adhesive, so that the safety of the end line can be ensured and the reliability of the resolver can be secured. Can do.
本発明によるレゾルバステータ構造は、端子ピンの数よりもたるみ用穴の数を多くすることにより、１本のたるみ用ピンには１本のみの端線が接するようにすることである。 The resolver stator structure according to the present invention is such that only one end line is in contact with one slack pin by increasing the number of slack holes rather than the number of terminal pins.
以下、図面と共に本発明によるレゾルバステータ構造の好適な実施の形態について説明する。
尚、従来例と同一又は同等部分には、同一符号を付して説明する。
図１において、符号１で示されるものは、所定角度間隔毎に内方に向けて突出する複数の突出磁極２を有する輪状ステータであり、前記輪状ステータ１の両端面には、一体又は別体にて形成された輪状絶縁カバー４が設けられている。
Hereinafter, preferred embodiments of a resolver stator structure according to the present invention will be described with reference to the drawings.
In addition, the same code | symbol is attached | subjected and demonstrated to a part the same as that of a prior art example, or an equivalent part.
In FIG. 1, what is indicated by reference numeral 1 is a ring-shaped stator having a plurality of projecting magnetic poles 2 projecting inward at predetermined angular intervals, and both end surfaces of the ring-shaped stator 1 are integrated or separated. A ring-shaped insulating cover 4 is provided.
前記各突出磁極２には、前記輪状絶縁カバー４を介してステータ巻線３が巻回され、前記輪状絶縁カバー４の一部には、前記輪状ステータ１の外側へ向けて突出する端子ピン保持部５が設けられている。
前記端子ピン保持部５には、たるみ用ピン８を着脱自在に設けるための貫通状の７個のたるみ用穴７が形成され、前記各たるみ用穴７の外側位置には、前記各たるみ用穴７の数よりも少ない６個の端子ピン６が設けられている。
A stator winding 3 is wound around each projecting magnetic pole 2 via the ring-shaped insulating cover 4, and a terminal pin holding a portion protruding toward the outside of the ring-shaped stator 1 is held on a part of the ring-shaped insulating cover 4. Part 5 is provided.
The terminal pin holding part 5 is formed with seven through holes 7 for sag to detachably attach the sag pins 8, and the sag holes 7 are provided at positions outside the sag holes 7. Six terminal pins 6 fewer than the number of holes 7 are provided.
前述の構成では、前記突出磁極２に巻回されたステータ巻線３の端線３ａは、前記各たるみ用ピン８を介して前記端子ピン６にからげられている。
前記端線３ａ、たるみ用ピン８及び端子ピン６の関係は、図２の拡大図に示されており、前記たるみ用ピン８がたるみ用穴７に対して着脱自在に設けられている。
In the above-described configuration, the end line 3 a of the stator winding 3 wound around the protruding magnetic pole 2 is tangled to the terminal pin 6 through the slack pins 8.
The relationship between the end line 3a, the sag pin 8 and the terminal pin 6 is shown in the enlarged view of FIG. 2, and the sag pin 8 is detachably provided to the sag hole 7. FIG.
前記端線３ａは、前記たるみ用ピン８の外周を約半分位周回して曲折した後に前記端子ピン６にからげられている。
前述の場合、前記各端子ピン６の数よりも前記たるみ用穴７の数が多いため、６本の前記端線３ａは、６個の前記たるみ用穴７の前記たるみ用ピン８を用いて前記各端子ピン６にからげられており、従来のように、図４で示されるような１本の前記たるみ用ピン８に対して複数の前記端線３ａがクロスした状態で互いに接触する必要もなく、１本のたるみ用ピン８に対して１本の端線３ａのみを前記たるみ用ピン８に接触させるだけで、たるみの形成ができる。
The end line 3a is bent by the terminal pin 6 after being bent by turning around the outer periphery of the sag pin 8 about half way.
In the above case, since the number of the slack holes 7 is larger than the number of the terminal pins 6, the six end lines 3 a use the slack pins 8 of the six slack holes 7. Each terminal pin 6 is entangled, and as in the prior art, a plurality of the end lines 3a need to be in contact with each other with a single slack pin 8 as shown in FIG. Of course, the slack can be formed by only bringing one end line 3a into contact with the slack pin 8 with respect to one slack pin 8.
従って、例えば、図示しないロータの軸倍角が変更となり、各突出磁極２に巻回されたステータ巻線３の巻線分布が変わった場合でも、前記たるみ用穴７の数が多く形成されているため、前記各端線３ａは何れかの前記たるみ用ピン８と接触又は係合することができるため、従来のような浮線の発生は避けることができる。
尚、前述の場合、前記たるみ用穴７によって前記端線３ａにたるみが形成された後は、前記たるみ用ピン８を前記たるみ用穴７から抜き取って除去し、前記端線３ａに形成されたくの字状のたるみ線３ａＡは、そのままの自由状態として外部からの振動による断線を防ぐとするか、又は、接着剤で前記端子ピン保持部５の一面に接着して固定させている。
Therefore, for example, even when the shaft multiplication angle of the rotor (not shown) is changed and the winding distribution of the stator winding 3 wound around each protruding magnetic pole 2 is changed, the number of the slack holes 7 is increased. Therefore, since each of the end lines 3a can contact or engage with any of the slack pins 8, the occurrence of floating lines as in the conventional case can be avoided.
In the above-described case, after the sag is formed in the end line 3a by the sag hole 7, the sag pin 8 is removed by being removed from the sag hole 7, and the end line 3a is desired to be formed. The U-shaped slack wire 3aA is used as it is in a free state to prevent disconnection due to external vibrations, or is adhered and fixed to one surface of the terminal pin holding portion 5 with an adhesive.
次に、本発明によるレゾルバステータ構造の要旨とするところは、次の通りである。
すなわち、所定角度間隔毎に内方へ向けて突出する複数の突出磁極２を有する輪状ステータ１と、前記輪状ステータ１に設けられた輪状絶縁カバー４を介して前記各突出磁極２に巻回されたステータ巻線３と、前記輪状絶縁カバー４の一端に一体形成され前記輪状ステータ１の外側へ突出する端子ピン保持部５と、前記端子ピン保持部５に設けられた複数のたるみ用穴７及び複数の端子ピン６と、を備え、前記たるみ用穴７にたるみ用ピン８が設けられている状態下で、前記突出磁極２に巻回されている前記ステータ巻線３の端線３ａが前記たるみ用ピン８を介して前記端子ピン６にからげられるように構成したレゾルバステータ構造において、前記たるみ用穴７の数は、前記端子ピン６の数よりも多い構成であり、また、前記各たるみ用ピン８に接触している前記端線３ａの線数は、1本のみである構成であり、また、前記たるみ用ピン８の除去後の前記たるみ線３ａＡは、自由状態あるいは接着剤による前記端子保持部への接着状態である構成である。
Next, the gist of the resolver stator structure according to the present invention is as follows.
That is, it is wound around each projecting magnetic pole 2 via a ring-shaped stator 1 having a plurality of projecting magnetic poles 2 projecting inward at predetermined angular intervals, and a ring-shaped insulating cover 4 provided on the ring-shaped stator 1. The stator winding 3, a terminal pin holding portion 5 that is integrally formed at one end of the annular insulating cover 4 and protrudes to the outside of the annular stator 1, and a plurality of slack holes 7 provided in the terminal pin holding portion 5. And an end line 3a of the stator winding 3 wound around the projecting magnetic pole 2 in a state in which the slack pin 8 is provided in the slack hole 7. In the resolver stator structure configured to be tangled to the terminal pin 6 via the sag pin 8, the number of the sag holes 7 is greater than the number of the terminal pins 6, and the Each slack The number of the end wires 3a in contact with 8 is only one, and the slack wire 3aA after the slack pins 8 are removed is held in the free state or the terminal by an adhesive. It is the structure which is the adhesion state to a part.
本発明によるレゾルバステータ構造は、端子ピン保持部に設けられたたるみ用穴の数を端子ピンの数よりも多くすることにより、１本のたるみ用ピンに複数の端線が接することもなく、軸倍角の変更等にも対応することができる。 The resolver stator structure according to the present invention increases the number of slack holes provided in the terminal pin holding portion from the number of terminal pins, so that a plurality of end lines do not contact one slack pin, It is also possible to deal with changes in shaft double angle.
