Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional double inversion type synchronous blower can not be manufactured at a low cost. <P>SOLUTION: Plastics (6) is made to flow in a rotating field (4) and a rotor (5) of the double inversion type synchronous blower so as to mold a magnetic field blade (4d) and a rotor blade (5c) at once. Magnetic flux return boards (3) are fitted to both sides. Consequently, the first and the last rotating fields (4) are allowed to employ the same mold. Thus, only one mold is required. Consequently, the presented method makes it possible to manufacture the disk type synchronous motor cheaper than the conventional axial flow-type blower and a centrifugal type fan. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT

Description

本発明はプラスチックで、モータと翼を一体化して成型する円盤型同期電動機に関するものである。
The present invention relates to a disk type synchronous motor which is made of plastic and integrally molds a motor and a blade.

従来の軸流圧縮機で電動機を使用して送風する場合、電動機の回転する力を、軸を介して軸流圧縮機に伝え、動翼で圧縮された気体は後置の静翼を通って第2段目の動翼に入る。この間、気体は動翼によりエネルギーを与えられ、静翼によって減少する。このように増減を繰り返して圧力を上昇させていたが、この方法では、軸流圧縮気と電動機が別々であるため大容量となっていた。また、静翼を使用していたため、動翼にエネルギーを与えられたものを、静翼によって減少させていたため効率が悪かった。   When a conventional axial flow compressor is used to blow air using an electric motor, the rotating force of the electric motor is transmitted to the axial flow compressor via the shaft, and the gas compressed by the moving blade passes through the rear stationary blade. Enter the second stage blade. During this time, the gas is energized by the moving blades and is reduced by the stationary blades. Although the pressure was increased by repeatedly increasing and decreasing in this way, this method has a large capacity because the axial flow compressed air and the electric motor are separate. Moreover, since the stationary blade was used, the energy given to the moving blade was reduced by the stationary blade, so the efficiency was poor.

そこで、軸流圧縮機と誘導電動機を一体化させた特開平4−192626の名称、逆回転軸流電動圧縮機では、ケーシングが軸を軸支し、その軸に取り付けた多数の回転磁界は回転子を交互に挟んで取り付け、回転磁界の外周には軸翼を取り付け、回転子の外周には回転子翼を取り付け、軸翼と回転子翼が互いに逆回転をして、静翼を使用しないものがあった。
しかし、逆回転軸流電動圧縮機では、誘導電動機を使用していたため回転子を制作するとき、かご型の回転子が薄く作り難いし、アルミダイカストが無いためアルミの鋳造所に発注したが、技量が無いため出力が出ず、制作費も高価になっていた。
Therefore, in the name of Japanese Patent Laid-Open No. 4-192626, in which an axial flow compressor and an induction motor are integrated, a reverse rotation axial flow electric compressor supports a shaft, and a number of rotating magnetic fields attached to the shaft rotate. Attaching the rotors alternately, attaching the shaft blades to the outer periphery of the rotating magnetic field, attaching the rotor blades to the outer periphery of the rotor, the shaft blades and the rotor blades rotate in reverse, and do not use the stationary blades There was a thing.
However, in reverse rotating axial flow electric compressors, induction motors were used, so when making the rotor, it was difficult to make a cage-shaped rotor thin, and because there was no aluminum die casting, we ordered from an aluminum foundry. Because there was no skill, there was no output and the production cost was expensive.

そこで、二重反転式同期送風機・特願2008−167050は逆回転軸流電動圧縮機と大部分は同じだが、回転子には、回転磁界の極数に合わして、永久磁石のN極とS極を配置しているだけであるから製作費が安価であったし、出力も圧倒的に高出力であった。   Therefore, the counter-rotating synchronous blower / Japanese Patent Application No. 2008-167050 is mostly the same as the counter-rotating axial flow electric compressor, but the rotor has a permanent magnet N pole and S in accordance with the number of poles of the rotating magnetic field. The production cost was low because only the poles were arranged, and the output was also overwhelmingly high.

特開平4−192626JP-A-4-192626 特願2008−167050Japanese Patent Application No. 2008-167050 特開平11−341717JP-A-11-341717

二重反転式同期送風機・特願2008−167050は逆回転軸流電動圧縮機と大部分は同じだが、回転子には、回転磁界の極数に合わして、永久磁石のN極とS極を作り、回転子を作っていたが、多少の制作費を押さえることができた。それでも、回転磁界を作るのが高価であった。   The counter-rotating synchronous blower / Japanese Patent Application No. 2008-167050 is mostly the same as the counter-rotating axial flow electric compressor, but the rotor has N and S poles of permanent magnets according to the number of poles of the rotating magnetic field. I made a rotator, but I was able to reduce some production costs. Nevertheless, creating a rotating magnetic field was expensive.

そこで、磁束返し盤(3)を取り付けることで、回転磁界(4)の型が一個で済み、回転磁界(4)と磁界翼(4d)、回転子(5)と回転子翼(5c)をプラスチック(6)を流して成型することで、安価な二重反転式同期送風機を提供する。
また、二重反転式同期送風機だけでなく、二重反転しない物を作っても、このプラスチック(6)を流し込む方法だと、製作費が安くなる円盤型同期電動機を提供するものである。
Therefore, by attaching the magnetic flux return plate (3), only one type of the rotating magnetic field (4) is required, and the rotating magnetic field (4) and the magnetic field blade (4d), and the rotor (5) and the rotor blade (5c) are provided. An inexpensive counter-rotating synchronous blower is provided by casting plastic (6).
In addition to the counter-rotating synchronous blower, it is possible to provide a disk-type synchronous motor that can be manufactured at a low cost when the plastic (6) is poured even if an article that does not counter-rotate is made.

そして回転子(5)には、回転磁界(4)の極数に合わして、永久磁石のN極とS極を同じ数だけ用意し、プラスチック(6)を流し込んで回転子翼(5c)を一体化して作ることで目的を達成した。

右は、鉄心(5c)にコイル(4b)を巻いたところである。三相の8極の回転磁界(4)で、一個の回転磁界(4)を作るとき、24個の鉄心(4c)が要り、図1の二重反転式同期送風機を制作するのに96個の鉄心(4c)と、コイル(4b)が要る。そのコイル(4b)は、並列配線をしているためφ0.2を3000回巻きアースへ繋く。したがって、コイル(4b)を3000回巻いても、厚みは2mmで良いため、従来にようにコイル(4b)を巻く場所を作らなくてよい。なお、コイル(4b)の配線の方法は、UWV相が3個続けば、U´W´V´相は鉄心(4c)をひっくり返して取り付ける。
FIG. 7 is a perspective view of the rotating magnetic field mold (4e), in which the protrusion corresponding to the shaft (2) for mounting the bearing (4a) at the center and the iron core (4c) around which the coil (4b) is wound There are 24 retracted parts for placing the wings, and there are wing types for making the magnetic field wings (4d) around them.

On the right, the coil (4b) is wound around the iron core (5c). When making one rotating magnetic field (4) with three-phase eight-pole rotating magnetic field (4), 24 iron cores (4c) are required, and 96 pieces are required to produce the counter rotating synchronous blower of FIG. Iron core (4c) and coil (4b) are required. Since the coil (4b) is connected in parallel, φ0.2 is wound 3000 times to connect to the ground. Therefore, even if the coil (4b) is wound 3000 times, the thickness may be 2 mm, so that it is not necessary to make a place for winding the coil (4b) as in the prior art. As for the wiring method of the coil (4b), if three UWV phases are continued, the U′W′V ′ phase is attached by turning over the iron core (4c).

図10は、回転磁界の型(4e)に、軸受(4a)を中央に配置し、その周りに鉄心(5c)にコイル(4b)を巻いたところの斜視図である。

このとき、鎹管(4i)を取り付けることで、軸(2)を傷付けず、適宜な場所で圧入できる。鎹管(4i)は1mmの鋼板を曲げて作り、回転磁界(4)の軸受(4a)と軸(2)とを繋ぐ役目をする。
キー(4g)の反対側には、コイル(4b)の線が穴から出ており、そのコイル(4b)を内部コード(7)に繋ぐ。
FIG. 10 is a perspective view of a rotating magnetic field mold (4e) in which a bearing (4a) is arranged in the center and a coil (4b) is wound around an iron core (5c) around the bearing (4a).
One of the coils (4b) is connected to the ground, and the other is connected to the UWV phase, and is taken out from a hole opened in the bearing (4a). There, it molds with the reinforced plastic (6) which hardens glass fiber with resin. In fact, two molds and thermosetting plastics are better for mass production, but they were stopped because there are two molds.
FIG. 11 is a perspective view of the completed rotating magnetic field (4), which has a key (4g) and a soot tube (4i). The key (4g) and the soot tube (4i) are attached to the shaft (2) of FIG. A rotating magnetic field (4) is inserted there, as shown in FIG.
At this time, it is possible to press-fit at an appropriate place without damaging the shaft (2) by attaching the soot tube (4i). The soot pipe (4i) is made by bending a 1 mm steel plate and serves to connect the bearing (4a) and the shaft (2) of the rotating magnetic field (4).
On the opposite side of the key (4g), the wire of the coil (4b) protrudes from the hole and connects the coil (4b) to the internal cord (7).

図13の回転子の型(5e)は、中央にベアリング受(5a)を取り付けるための出っ張りがある。その回りには、磁石(5b)を取り付けるための、引っ込んだ部分が8個付いていて、その外側には回転子翼(5c)を作るための翼の型になっている。
図14の斜視図はベアリング受(5a)であり、図15の断面図で示したベアリング受(5a)は、ベアリング(8)を両端から挿入する部品で、それを図13の回転子の型(5e)の中央に置く。
その周りに、図16の斜視図の磁石(5b)を8個置いた図が、図17の斜視図である。 ベアリング受(5a)は、上部の固定がしっかりしていないときには、仮のベアリング(8)を入れておくとよい。
そこに、ガラス繊維を樹脂で固める強化プラスチック(6)で成型する。
The rotor mold (5e) in FIG. 13 has a ledge for attaching the bearing receiver (5a) at the center. Around that, there are eight retracted parts for attaching the magnet (5b), and on the outer side is a wing shape for making the rotor wing (5c).
The perspective view of FIG. 14 is a bearing receiver (5a). The bearing receiver (5a) shown in the sectional view of FIG. 15 is a part into which the bearing (8) is inserted from both ends. Place in the center of (5e).
FIG. 17 is a perspective view in which eight magnets (5b) in the perspective view of FIG. 16 are placed around it. When the upper part of the bearing receiver (5a) is not firmly fixed, a temporary bearing (8) may be inserted.
There, it molds with the reinforced plastic (6) which hardens glass fiber with resin.

図18の斜視図は、回転子の型(5e)から回転子(5)を取り出した図である。ベアリング受(5a)に、ベアリング(8)を両端から取り付ける。なお、ベアリング(8)とベアリング(8)の間にカラー(座金)を入れておく。カラーは、ベアリング(8)に横からの力が加わると、ベアリング(8)がスムーズに回らないので取り付ける。
次に鎹筒(5i)は、1mmの鋼板を曲げて作る。
図19の断面図は、図12の断面図に回転子(5)を取り付けた図である。まず、回転子(5)を取り付ける前に、座金(2b)を軸(2)に挿入する。座金(2b)は、回転磁界(4)と回転子(5)のギャップを決める部品であり、0.5mmくらいが理想である。次に、鎹筒(5i)を軸(2)に挿入した後で、回転子(5)を圧入する。
The perspective view of FIG. 18 is a view of the rotor (5) taken out from the rotor mold (5e). The bearing (8) is attached to the bearing receiver (5a) from both ends. A collar (washer) is placed between the bearing (8) and the bearing (8). The collar is attached because the bearing (8) does not rotate smoothly when a lateral force is applied to the bearing (8).
Next, the gutter (5i) is made by bending a 1 mm steel plate.
The cross-sectional view of FIG. 19 is a view in which the rotor (5) is attached to the cross-sectional view of FIG. First, before attaching the rotor (5), the washer (2b) is inserted into the shaft (2). The washer (2b) is a component that determines the gap between the rotating magnetic field (4) and the rotor (5), and about 0.5 mm is ideal. Next, after inserting the bush (5i) into the shaft (2), the rotor (5) is press-fitted.

その回転磁界(4)と回転子(5)を多数取り付け、最後に磁束返し盤(3)を挿入して、ベアリング(8)を介してケーシング(1)に取り付けるここで、図20の断面図のようになる。 その図は、図1の斜視図と同じ状態でありる。   A large number of the rotating magnetic field (4) and the rotor (5) are attached, and finally the magnetic flux return plate (3) is inserted and attached to the casing (1) through the bearing (8). become that way. The figure is the same as the perspective view of FIG.

二重反転しない同期送風機の回転磁界(4)は、磁束返し盤(3)と軸(2)を一体化して作る。
そして、軸(2)の周りに、コイル(4b)を巻いた鉄心(4c)を磁束返し盤(3)の上に置き、プラスチック(6)で成型する。
次に回転子(5)は、磁束返し盤(3)とベアリング受(5a)を一体化して配置し、その回りに磁石(5b)を並べ、そこへプラスチック(6)を流し込んで、回転子(5)と回転子翼(5c)を同時に成型する。
そのとき、回転子翼(5c)は軸流型と遠心型のどちらでもよい。
そして、ベアリング受(5a)の中へ、ベアリング(8)を取り付けて、軸(2)を挿入するので、ベアリング(8)の大きさは、回転子(5)に近い方から大きい物を取り付け、奥の部分には小さな物を取り付けると、ベアリング(8)を長い距離、圧入しなくてすむ。
さらに、回転子(5)は取り外しが簡単であるから、回転子(5)だけを外して回転子翼(5c)を掃除できるので便利である。
The rotating magnetic field (4) of the synchronous blower that does not reverse inversion is formed by integrating the magnetic flux return plate (3) and the shaft (2).
Then, the iron core (4c) around which the coil (4b) is wound is placed on the magnetic flux return plate (3) around the shaft (2) and molded with plastic (6).
Next, in the rotor (5), the magnetic flux return plate (3) and the bearing receiver (5a) are integrally arranged, the magnet (5b) is arranged around the rotor, and the plastic (6) is poured into the rotor (5). (5) and the rotor blade (5c) are molded simultaneously.
At that time, the rotor blade (5c) may be either an axial flow type or a centrifugal type.
And since the bearing (8) is installed in the bearing receiver (5a) and the shaft (2) is inserted, the size of the bearing (8) is larger from the side closer to the rotor (5). When a small object is attached to the back part, it is not necessary to press-fit the bearing (8) for a long distance.
Furthermore, since the rotor (5) is easy to remove, it is convenient because only the rotor (5) can be removed to clean the rotor blade (5c).

本発明の二重反転しない円盤型同期電動機は、回転子翼(5c)の変わりにタイヤを取り付けると、電動車にも使用できる。この電動機は、性質上磁石(5b)が鉄心(4c)を引き寄せているので、タイヤの付いた回転子(5)は外れないが、外すときは工具などで少しギャップを広げると磁石(5b)に吸着力は落ちるので、タイヤを外すことがでできる。したがって、ボルトなどがいっさい不要である。   The disk-type synchronous motor of the present invention that does not invert can be used for an electric vehicle when a tire is attached instead of the rotor blade (5c). In this motor, since the magnet (5b) attracts the iron core (4c) by nature, the rotor (5) with the tire cannot be removed, but when removing the magnet (5b) Since the adsorption power drops, the tire can be removed. Therefore, no bolts are necessary.

また、本発明はプラスチック(6)で整形しているため、水中ポンプなどに使用することができる。
さらに、回転子(5)をアルミ盤にしたら、ベアリング(8)やギャップを気にしなくとも、回転磁界(4)に電気を流すと浮き上がり、回転することができるので、過酷なところにも使用できる。
Moreover, since the present invention is shaped with plastic (6), it can be used for submersible pumps and the like.
Furthermore, if the rotor (5) is made of aluminum, it can float and rotate when electricity is applied to the rotating magnetic field (4) without worrying about the bearings (8) and gaps. it can.
