本発明は、冗長系レゾルバに関し、特に、複数の系統角度検出部の渡り線を、各系統角度検出部毎に前記輪状ステータの第１面と第２面に分けて配設し、各系統間の短絡を防止し、冗長系を確保して機能低下とならないようにするための新規な改良に関する。 The present invention relates to a redundant resolver, and in particular, the connecting wires of a plurality of system angle detectors are arranged separately for each system angle detector on the first surface and the second surface of the annular stator, The present invention relates to a novel improvement for preventing a short circuit and preventing a function deterioration by securing a redundant system.
従来、用いられていたこの種のレゾルバとしては、特許文献１等で示される構成を挙げることができる。
すなわち、この特許文献１で示されるレゾルバを第１、第２系統角度検出部からなる冗長系レゾルバとして用いると、図４及び図５で示される構成となる。
図４及び図５において符号１で示されるものは、輪状ステータであり、この輪状ステータ１の内方へ向けて突出する各磁極１ａには各磁極１ａ間のスロット(図示せず)内に位置するようにステータ巻線２が巻回されている。
Conventionally, this type of resolver includes the configuration shown in Patent Document 1 and the like.
That is, when the resolver disclosed in Patent Document 1 is used as a redundant resolver including first and second system angle detection units, the configuration illustrated in FIGS. 4 and 5 is obtained.
4 and 5 is a ring-shaped stator, and each magnetic pole 1a protruding inward of the ring-shaped stator 1 is positioned in a slot (not shown) between the magnetic poles 1a. Thus, the stator winding 2 is wound.
前記ステータ巻線２は、この輪状ステータ１の０−１８０度及び１８０−３６０度で２分割されて各々独立し、図で格子部分と白部分で示すように、第１系統角度検出部３及び第２系統角度検出部４が形成されている。 The stator winding 2 is divided into two parts at 0-180 degrees and 180-360 degrees of the ring-shaped stator 1 and is independent of each other. As shown by a lattice part and a white part in the figure, the first system angle detection unit 3 and A second system angle detection unit 4 is formed.
前記各系統角度検出部３，４における各磁極１ａ間を渡る渡り線５，６は、輪状ステータ１の第１面１Ａに配設されている。
前記各系統角度検出部３，４は各々独立し、図示しないロータが回転することにより、各系統角度検出部３，４からは同一の回転検出信号が出力され、２Ｘ（Ｘは軸倍角）の検出機能が得られるように構成されている。
Crossovers 5 and 6 between the magnetic poles 1 a in the system angle detectors 3 and 4 are disposed on the first surface 1 A of the annular stator 1.
The system angle detectors 3 and 4 are independent of each other, and the same rotation detection signal is output from the system angle detectors 3 and 4 by rotating a rotor (not shown), and 2X (X is a shaft angle multiplier). The detection function is configured to be obtained.
従来の冗長系レゾルバは、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、各系統角度検出部の渡り線を輪状ステータの第１面側に全て混合して配設していたため、各系統の渡り線が互いに重合又は交叉状態（図５の接触部分）となり、各系統間の短絡の発生、あるいは、レゾルバの機能低下となる虞がある。
Since the conventional redundant resolver is configured as described above, the following problems exist.
That is, since the crossover wires of each system angle detection unit are all mixed and arranged on the first surface side of the ring-shaped stator, the crossover wires of each system are superposed or crossed with each other (contact portion in FIG. 5). There is a risk that a short circuit between the systems will occur or the function of the resolver will deteriorate.
本発明による冗長系レゾルバは、複数の突出した磁極を有する１個の輪状ステータと、前記輪状ステータに設けられた複数の系統角度検出部とを備え、同一の前記磁極に前記複数の系統角度検出部のためのステータ巻線が巻回されていないようにした冗長系レゾルバにおいて、前記複数の系統角度検出部のステータ巻線の各磁極間に渡る渡り線は、前記各系統角度検出部毎に前記輪状ステータの第１面と第２面に分けて配設した構成であり、また、前記各系統角度検出部は、前記輪状ステータの１８０度毎に分けて形成されている構成であり、また、前記各系統角度検出部は、前記輪状ステータの９０度毎に分けて形成されている構成であり、また、前記各系統角度検出部は、前記輪状ステータの２ｎ分割した角度毎に分けて形成されている構成である。 A redundant resolver according to the present invention includes a ring-shaped stator having a plurality of projecting magnetic poles and a plurality of system angle detection units provided on the ring-shaped stator, and the plurality of system angle detections on the same magnetic pole. In the redundant system resolver in which the stator windings for the parts are not wound, the crossovers between the magnetic poles of the stator windings of the plurality of system angle detectors are provided for each system angle detector. The ring-shaped stator is configured to be divided into a first surface and a second surface, and each system angle detection unit is formed to be divided at every 180 degrees of the ring-shaped stator, and The system angle detectors are formed separately for each 90 degrees of the ring-shaped stator, and the system angle detectors are divided for every 2n- divided angles of the ring-shaped stator. Formed It is a configuration.
本発明による冗長系レゾルバは、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、複数の系統角度検出部の渡り線を、各系統角度検出部毎に輪状ステータの第１面と第２面に分けて配設しているため、各系統間の短絡を防止し、冗長系を確保してレゾルバの機能低下を防止することができる。
Since the redundant resolver according to the present invention is configured as described above, the following effects can be obtained.
That is, since the connecting wires of the plurality of system angle detection units are arranged separately for the first surface and the second surface of the ring-shaped stator for each system angle detection unit, a short circuit between each system is prevented and redundancy is achieved. The system can be secured to prevent the resolver from deteriorating.
本発明は、複数の系統角度検出部の渡り線を、各系統角度検出部毎に前記輪状ステータの第１面と第２面に分けて配設し、各系統間の短絡を防止し、冗長系を確保して機能低下とならないようにした冗長系レゾルバを提供することを目的とする。 In the present invention, the crossover wires of the plurality of system angle detection units are arranged separately for each system angle detection unit on the first surface and the second surface of the ring-shaped stator, thereby preventing a short circuit between the systems and providing redundancy. It is an object of the present invention to provide a redundant resolver that secures a system so as not to deteriorate the function.
以下、図面と共に本発明による冗長系レゾルバ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用いて説明する。
図１において符号１で示されるものは、輪状ステータであり、この輪状ステータ１の内方へ向けて突出する各磁極１ａには各磁極１ａ間のスロット(図示せず)内に位置するようにステータ巻線２が巻回されている。
Hereinafter, preferred embodiments of a redundant resolver according to the present invention will be described with reference to the drawings.
The same reference numerals are used for the same or equivalent parts as in the conventional example.
1 is a ring-shaped stator, and the magnetic poles 1a projecting inward of the ring-shaped stator 1 are positioned in slots (not shown) between the magnetic poles 1a. The stator winding 2 is wound.
前記ステータ巻線２は、１例として、この輪状ステータ１の０−１８０度及び１８０−３６０度で２分割されて各々独立し、図で格子部分と白部分で示すように、第１系統角度検出部３及び第２系統角度検出部４が形成されている。 As an example, the stator winding 2 is divided into two parts at 0-180 degrees and 180-360 degrees of the ring-shaped stator 1 and is independent of each other. A detection unit 3 and a second system angle detection unit 4 are formed.
前記第１系統角度検出部３における各磁極１ａ間を渡る第１系統渡り線５は、図２に示されるように、輪状ステータ１の第１面１Ａに配設され、前記第２系統角度検出部４における各磁極１ａ間を渡る第２系統渡り線６は、図３に示されるように、輪状ステータ１の第２面１Ｂに配設されている。従って、各渡り線５，６が互いに同一面で重合する等となることはないように構成されている。 As shown in FIG. 2, the first system crossover 5 between the magnetic poles 1a in the first system angle detection unit 3 is disposed on the first surface 1A of the annular stator 1, and the second system angle detection is performed. As shown in FIG. 3, the second system connecting wire 6 that extends between the magnetic poles 1 a in the portion 4 is disposed on the second surface 1 </ b> B of the annular stator 1. Accordingly, the crossover wires 5 and 6 are configured not to be superposed on the same surface.
前記第１、第２系統角度検出部３，４におけるステータ巻線２は、各々各系統角度検出部３，４内の各磁極１ａのみに巻回され、各磁極１ａには各系統角度検出部３，４の何れかのみのステータ巻線２が巻回されている。従って、同一の磁極１ａに各系統角度検出部３，４のステータ巻線２が混合して巻回されることはない。 The stator windings 2 in the first and second system angle detectors 3 and 4 are wound only on the magnetic poles 1a in the system angle detectors 3 and 4, respectively. Only one of the stator windings 3 is wound. Therefore, the stator windings 2 of the system angle detectors 3 and 4 are not mixed and wound around the same magnetic pole 1a.
前記各系統角度検出部３，４は各々独立し、図示しないロータが回転することにより、各系統角度検出部３，４からは同一の回転検出信号が出力され、２Ｘ(Ｘは軸倍角)の検出機能が得られるように構成されている。 The system angle detectors 3 and 4 are independent of each other, and the same rotation detection signal is output from the system angle detectors 3 and 4 by rotating a rotor (not shown). The detection function is configured to be obtained.
前記第１、第２系統角度検出部３，４の検出信号は、第１、第２リード線２０，２１を介して外部に出力されるように構成され、前記第１リード線２０は前記第１面１Ａ側に位置し、前記第２リード線２１は前記第２面１Ｂ側に位置している。 The detection signals of the first and second system angle detectors 3 and 4 are output to the outside via the first and second lead wires 20 and 21, and the first lead wire 20 is Located on the first surface 1A side, the second lead wire 21 is positioned on the second surface 1B side.
また、前述の構成においては、各系統角度検出部３，４は、１８０度毎の２系統の冗長系として構成した場合について述べたが、例えば、図示していないが、９０度毎の４分割による４重冗長系、４５度毎の８分割による８重冗長系、２２．５度毎の１６分割等の２ｎ分割した角度毎に分けた冗長系の構成を得ることもできる。 In the above-described configuration, the system angle detection units 3 and 4 have been described as being configured as two redundant systems every 180 degrees. For example, although not shown, the system angle detection units 3 and 4 are divided into four parts every 90 degrees. It is also possible to obtain a redundant system configuration divided into 2n- divided angles, such as a quadruple redundant system, an 8-redundant system with 8 divisions every 45 degrees, and a 16-divided system with 22.5 degrees.
本発明は、１個の輪状ステータを用いるだけでなく、複数の輪状ステータを用いることにより、より多重冗長系に適用することも可能である。 The present invention can be applied to a multiple redundant system by using not only a single ring-shaped stator but also a plurality of ring-shaped stators.
