Description
本発明は、アウターロータレゾルバ用ステータ構造に関し、特に、ステータ鉄心の内壁に切り欠け状の部を形成し、ステータ鉄心の外周縁に一体に成形した樹脂成形部を前記凹部に端子保持部として延設することにより、リード線を不要とし、自動巻き線及び自動からげを可能とするための新規な改良に関する。 The present invention relates to a stator structure for an outer rotor resolver, and in particular, a notched portion is formed on an inner wall of a stator core, and a resin molded portion formed integrally with the outer periphery of the stator core is extended as a terminal holding portion to the recess. The present invention relates to a novel improvement that eliminates the need for lead wires and enables automatic winding and automatic tangling.
従来、用いられていたこの種のアウターロータレゾルバ用ステータ構造としては、例えば、特許文献１に示されるインナーロータレゾルバ用ステータ構造を応用して図３で示される構成が採用されていた。
すなわち、図３において符号１で示されるものは、輪状ステータ鉄心であり、このステータ鉄心１の両面には、図示しない一対の輪状絶縁カバーを介して各スロット(図示せず)にステータコイル２が巻付けられている。
As this type of conventionally used outer rotor resolver stator structure, for example, the configuration shown in FIG. 3 was adopted by applying the inner rotor resolver stator structure disclosed in Patent Document 1.
That is, what is denoted by reference numeral 1 in FIG. 3 is a ring-shaped stator core, and stator coils 2 are provided on both surfaces of the stator core 1 in respective slots (not shown) via a pair of ring-shaped insulating covers (not shown). It is wound.
前記ステータコイル２の端線は、端末処理部３に導かれ、リード線４によって外部へ導出されるように構成されている。
前記ステータ鉄心１の外周位置には、周知のバリアブルリラクタンス(VR)型の輪状ロータ５が回転可能に配設されている。
An end line of the stator coil 2 is led to the terminal processing unit 3 and led to the outside by the lead wire 4.
A known variable reluctance (VR) type annular rotor 5 is rotatably disposed at an outer peripheral position of the stator iron core 1.
従来のアウターロータレゾルバ用ステータ構造は、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、ステータ鉄心の両面に別体で形成された一対の輪状絶縁カバーを介して各スロットにステータコイルを巻付け、このステータコイルの端線の端末処理は、各端線が端末処理部に集められ、人手を介してリード線に接続しなければならず、レゾルバの組立てが人手に頼る部分が多く、自動組立てに対する大きい障害となっていた。
また、ステータ鉄心の内径はレゾルバを取付ける面となるため、この内径側には端子を取付けるためのスペースが全く形成されていなかった。
Since the conventional stator structure for an outer rotor resolver is configured as described above, the following problems exist.
That is, a stator coil is wound around each slot via a pair of ring-shaped insulating covers formed separately on both sides of the stator core, and terminal processing of the end lines of the stator coil is performed by collecting each end line in the terminal processing section. In other words, the resolver has to be connected to the lead wire manually, and there are many parts where the resolver is relied on manually, which is a major obstacle to automatic assembly.
Further, since the inner diameter of the stator iron core is a surface to which the resolver is attached, no space for attaching a terminal is formed on the inner diameter side.
本発明による、アウターロータレゾルバ用ステータ構造は、全体形状が輪状をなし外方へ向けて突出する複数の磁極を有し、前記各磁極の外側に輪状ロータが配設されるようにしたステータ鉄心からなるアウターロータレゾルバ用ステータ構造において、
前記ステータ鉄心の内壁に形成された凹部と、前記ステータ鉄心の外周縁部に前記ステータ鉄心と一体に成形され前記各磁極を覆う樹脂成形部と、前記樹脂成形部と一体成形され前記凹部に位置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端子ピンとを備えている構成であり、また、前記凹部は複数よりなる構成であり、また、前記端子ピン保持部の保持内面は、前記ステータ鉄心の内壁と面一に形成されている構成である。
A stator structure for an outer rotor resolver according to the present invention has a plurality of magnetic poles whose overall shape is annular and protrudes outward, and a stator iron core in which an annular rotor is disposed outside each of the magnetic poles. In the stator structure for an outer rotor resolver consisting of
A recess formed in the inner wall of the stator core, a resin molded portion formed integrally with the stator core on the outer peripheral edge of the stator core, and covering each magnetic pole; and a resin molded portion formed integrally with the resin molded portion; And a plurality of terminal pins provided in the terminal pin holding part, and the concave part is constituted by a plurality of parts, and a holding inner surface of the terminal pin holding part Is a structure that is formed flush with the inner wall of the stator core.
本発明によるアウターロータレゾルバ用ステータ構造は、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、ステータ鉄心の内壁に形成した凹部を有し、ステータ鉄心の外周縁に一体形成形した樹脂成形部の一部に形成される端子保持部をこの凹部内に形成しているため、この端子保持部の各端子にステータコイルの端線を自動機でからげて端末処理することができる。
また、凹部に樹脂成形部の端子保持部が一体成形で延設されているため、ステータの外周縁に形成された樹脂成形部のステータ鉄心への付着安定性も向上する。
また、ステータ鉄心に端子ピン保持部が形成されているため、従来のようなリード線を用いる必要がなく、アウターロータ型レゾルバの自動組立てを行うことができる。
Since the stator structure for an outer rotor resolver according to the present invention is configured as described above, the following effects can be obtained.
In other words, the terminal holding part formed in a part of the resin molded part formed integrally with the outer peripheral edge of the stator core is formed in the concave part formed in the inner wall of the stator iron core. An end line of the stator coil can be tangled with an automatic machine at each terminal of the holding portion to perform terminal processing.
In addition, since the terminal holding portion of the resin molding portion is integrally formed in the recess, the adhesion stability of the resin molding portion formed on the outer peripheral edge of the stator to the stator core is also improved.
Further, since the terminal pin holding portion is formed on the stator iron core, it is not necessary to use a lead wire as in the prior art, and the outer rotor type resolver can be automatically assembled.
本発明は、ステータ鉄心の内壁に切り欠け状の凹部を形成し、ステータ鉄心の外周縁に一体に成形した樹脂成形部を前記凹部に端子保持部として延設することにより、リード線を不要とし、自動巻き線及び自動からげを可能としたアウターロータレゾルバ用ステータ構造を提供することを目的とする。 The present invention eliminates the need for a lead wire by forming a notch-shaped recess in the inner wall of the stator core and extending a resin molded portion integrally formed on the outer peripheral edge of the stator core as a terminal holding portion in the recess. An object of the present invention is to provide a stator structure for an outer rotor resolver that enables automatic winding and automatic lashing.
以下、図面と共に本発明によるアウターロータレゾルバ用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用いて説明する。また、輪状ロータについては、図３の構成と同一であるため、図示を省略し、図３の構成を援用する。
図１において、符号１で示されるものは全体形状が輪状をなし、外方へ向けて一体に突出する複数の磁極１０を有するステータ鉄心であり、このステータ鉄心１の内壁１ａには複数（１個の場合も可）の凹部１１が所定再度間隔で形成されている。
Hereinafter, preferred embodiments of a stator structure for an outer rotor 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. Moreover, since it is the same as that of the structure of FIG. 3 about a ring-shaped rotor, illustration is abbreviate | omitted and the structure of FIG. 3 is used.
In FIG. 1, what is indicated by reference numeral 1 is a stator iron core having a plurality of
前記ステータ鉄心１の外周縁部１２には、インサート成形によって樹脂成形部１３が輪状に形成され、この樹脂成形部１３の一部には端子ピン保持部１４が一体に形成され、この端子ピン保持部１４は前記凹部１１内に位置し、この凹部１１と一体となるように成形されている。 A resin molded portion 13 is formed in a ring shape on the outer peripheral edge portion 12 of the stator iron core 1 by insert molding, and a terminal pin holding portion 14 is formed integrally with a part of the resin molded portion 13, and this terminal pin holding The portion 14 is located in the recess 11 and is formed so as to be integrated with the recess 11.
前記樹脂成形部１３の内側には、前記ステータ鉄心１の内周縁１ｂが外部に露出して前記樹脂成形部１３が形成されていないように構成されている。
図２は、図１のＡ部を拡大して示すもので、前記凹部１１に成形により形成された端子ピン保持部１４には複数の端子ピン１５が一体に成形によって保持されている。
前記端子ピン保持部１４の保持内面１４ａは、円弧状に形成されると共にステータ鉄心１の内壁１ａと同一円周上でかつ面一となるように構成されている。
Inside the resin molding part 13, the inner peripheral edge 1 b of the stator core 1 is exposed to the outside so that the resin molding part 13 is not formed.
FIG. 2 is an enlarged view of the portion A of FIG. 1, and a plurality of terminal pins 15 are integrally held by the terminal pin holding portion 14 formed in the concave portion 11 by molding.
A holding inner surface 14 a of the terminal pin holding portion 14 is formed in an arc shape and is configured to be flush with and flush with the inner wall 1 a of the stator core 1.
前述の構成において、実際に、各磁極１０、すなわち、各磁極１０間の各スロット２０にステータコイルを設ける場合、自動巻線機（図示せず）を介してステータコイル２を各磁極１０に巻付けるが、巻付け後のステータコイル２の端線の端末処理は、この端線を各端子ピン１５に自動的にからげて接続することにより行なわれる。
In the above-described configuration, when a stator coil is actually provided in each
従って、ステータコイル２の端末処理に、従来のようなリード線を用いることがないため、全自動による巻線処理を行うことができる。 Therefore, a lead wire as in the prior art is not used for the terminal processing of the stator coil 2, so that a fully automatic winding process can be performed.
本発明は、レゾルバに限ることなく、アウターロータ型のモータにも適用可能である。 The present invention is not limited to a resolver but can be applied to an outer rotor type motor.
