Description

この発明は、ボビン式巻線による電機子巻線と磁極鉄心とによって形成する直流及び交流電磁石を複数個組み合わせて使われる回転電機と、誘導電動機等を一体とした複合回転電機として、小型機器から大型機器までの分野への普及拡大に関する。   This invention relates to a rotating electrical machine that is a combination of a plurality of direct current and alternating current electromagnets formed by an armature winding by a bobbin winding and a magnetic core, and a combined rotating electrical machine that integrates an induction motor and the like, from a small device. It is related to the spread expansion to the field to large equipment.

従来から誘導電動機は回転子には起動用誘導体としてかご形のスロットバーと回転子鉄心の両側面にスロットバーと一体成型された短絡環とより形成され自己起動形電動機として広く使用されている。誘導電動機は固定子電機子巻線の1次導体に電源が印加されると回転磁界が発生し、この磁束が回転子の起動用2次かご形誘導体に鎖交することにより導体内に誘導電流が流れ、回転磁界と作用してトルクを生じて回転し始める。即ち本電動機は誘導電動機として起動する。   2. Description of the Related Art Conventionally, induction motors are widely used as self-starting motors, which are formed of a cage-type slot bar and a short-circuit ring integrally formed with a slot bar on both sides of the rotor core as starting derivatives. The induction motor generates a rotating magnetic field when power is applied to the primary conductor of the stator armature winding, and this magnetic flux interlinks with the secondary squirrel-cage derivative for starting the rotor. Flows, acts on the rotating magnetic field, generates torque, and starts rotating. That is, this motor is started as an induction motor.

また、同期電動機は回転数が同期速度近くに達すると回転子は永久磁石の作る磁極によって同期速度に引込まれたのち電源周波数に同期した同期運転を行うこととなる。
回転子に永久磁石が配置された同期電動機は永久磁石の発生する磁束があるために励磁電力は不要となり、高い効率と力率が得られるとともに負荷変動があっても回転数は常に電源周波数に同期した定速運転ができる等のすぐれた点を有する。
最近の同期電動機は回転子には永久磁石が埋め込まれている永久磁石式同期電動機として定速度運転性及び高効率・高力率の観点から広く使用されつつある。
特に永久磁石の希土類材料の発展により高性能化、小形化の進歩が著しい状況にある。
Further, when the rotational speed of the synchronous motor reaches near the synchronous speed, the rotor is pulled to the synchronous speed by the magnetic pole formed by the permanent magnet, and then performs synchronous operation synchronized with the power supply frequency.
A synchronous motor with a permanent magnet on the rotor has a magnetic flux generated by the permanent magnet, so no excitation power is required, and high efficiency and power factor can be obtained. It has excellent features such as synchronized constant speed operation.
Recent synchronous motors are widely used as permanent magnet type synchronous motors in which permanent magnets are embedded in the rotor from the viewpoints of constant speed operation, high efficiency, and high power factor.
In particular, the progress of high performance and miniaturization is remarkable due to the development of rare earth materials for permanent magnets.

永久磁石同期電動機においては、当然のことながら、同期速度に達して始めてトルクを同一の方向に生じるのであって、そのままでは起動トルクはほとんどゼロに近い。同期電動機は起動時の電源周波数が極く低い場合を除いて自力で起動することができない。そこで商用周波数の電源で運転するには、同期電動作用に誘導電動作用を持たせるためには、起動トルクを発生する方法を講じなければならない。起動方法のひとつに回転子に起動用かご形誘導体を配置し、固定子により形成される回転磁界と、この回転磁界により起動用誘導体に誘起される誘導電流との相互作用により起動トルクを発生させる。誘導電動作用として作動させ、起動させている。その上同期速度に達した時点で同期運転が開始される。
このような特性の永久磁石式同期電動機においては、誘導体は回転子において永久磁石の外側に配置されている。これは、固定子の形成する回転磁界を永久磁石の磁界が阻害して、誘導体と交差する磁束が減じられ、または乱されて、誘導電動機としての起動特性を悪化させないようにするためである。この場合でも、誘導電動機として運転される領域において、永久磁石により固定子により形成される磁界に影響を与え、起動特性を悪化させ、すべり周波数での電磁力の脈動が外乱として作用し同期引入れが安定しないという問題がある。2次かご形誘導体を設ける形式の永久磁石電動機では起動時の誘導電動機2次リアクタンスに対し2次抵抗が大きく起動トルクは大きいが、同期速度付近で著しくトルクが減少するため同期引入れを安定化することが困難である。また、このような配置によれば、永久磁石と固定子の距離が必然的に離れ、永久磁石が回転子の表面近傍に配置された場合に比べてトルクが小さくなるという問題がある。また、永久磁石は通常高価な材料を多数使用することになり、性能とコスト面から見て好ましいものではない。
In the permanent magnet synchronous motor, as a matter of course, the torque is generated in the same direction only after reaching the synchronous speed, and the starting torque is almost zero as it is. Synchronous motors cannot be started on their own unless the power supply frequency at startup is very low. Therefore, in order to operate with a commercial frequency power supply, a method for generating a starting torque must be taken in order to provide the synchronous electric action with the induction electric action. One of the starting methods is to arrange a starting cage derivative on the rotor and generate a starting torque by the interaction between the rotating magnetic field formed by the stator and the induced current induced in the starting derivative by this rotating magnetic field. . It is activated and activated as an induction motor. In addition, synchronous operation is started when the synchronous speed is reached.
In the permanent magnet type synchronous motor having such characteristics, the derivative is disposed outside the permanent magnet in the rotor. This is to prevent the rotating magnetic field formed by the stator from being obstructed by the magnetic field of the permanent magnet so that the magnetic flux intersecting with the derivative is reduced or disturbed so that the starting characteristics of the induction motor are not deteriorated. Even in this case, in the region where the motor is operated as an induction motor, the magnetic field formed by the stator by the permanent magnet is affected, the start-up characteristics are deteriorated, and the pulsation of the electromagnetic force at the slip frequency acts as a disturbance and is synchronized. There is a problem that is not stable. Permanent magnet motors with a secondary squirrel-cage derivative have a large secondary resistance and a large starting torque with respect to the secondary reactance of the induction motor at the time of starting. Difficult to do. In addition, according to such an arrangement, there is a problem that the distance between the permanent magnet and the stator is inevitably increased, and the torque becomes smaller than when the permanent magnet is arranged near the surface of the rotor. In addition, permanent magnets usually use many expensive materials, which is not preferable from the viewpoint of performance and cost.

さらにまた、従来、前述の問題を避けるために、同期電動機と誘導電動機とを分けて同一回転軸に一体に組込む方法が行われている場合がとられているが、同期電動機も誘導電動機もともに、回転軸に対して同一円筒面に、固定子には電磁結合のための電機子巻線は分布巻きが行われていることによって、構成の本質において磁気的に干渉を受けやすく性能の低下、または大型化を伴っていた。従って、複合一体にした意味が大きく減じられていた。   Furthermore, conventionally, in order to avoid the above-mentioned problem, there has been a case where a synchronous motor and an induction motor are separately integrated into the same rotating shaft, but both the synchronous motor and the induction motor are used. In the same cylindrical surface with respect to the rotation axis, the armature winding for electromagnetic coupling is distributed to the stator, so that it is susceptible to magnetic interference in the essence of the configuration, and the performance deteriorates. Or it was accompanied by an increase in size. Therefore, the meaning of compounding was greatly reduced.

また、同期電動機も誘導電動機もともに、固定子には電磁結合のための電機子巻線は分布巻きが行われていることと、且つ、積層した電磁鋼板に巻線挿入用に設けられているスロットに巻線を組み込み製作されている。
従って、同期電動機においては、この状態では、巻線組み込み後巻線端部を接続、エンドコイルの成形や固定等非常に複雑面倒な作業で作業性が悪く、工程も長く、作業中の傷付き等による使用時絶縁破壊等の信頼性の低下、狭いスロットや巻線間の絡みや干渉、または組線作業の作業性をよくする為のスロット占積率の低下(通常50%),余分なエンドコイルの延長によるコスト増、エンドコイル部の抵抗損の増加や漏洩磁束の増加等による効率低下や出力低下等をまねいていた。また生産の機械化が難しく、それを実施した場合に設備費に多額の費用がかかっていた。また低電圧や中型・大型機器の場合巻線の徑が大きくなり一層作業性を悪くしてさらに大幅なコスト高になっていた。このため、固定子における同期電動機の性能、小形化、生産性の進展を阻害していた。
また、従来の構造で極数を変更する場合巻き線を変えて行っているが、特別に鉄心の外形を大きくして対処する場合は別として、通常8極が限度となっている。従来の回転電機は低速、小出力時の効率が非常に低く磁石式回転電機でも20から30%が一般的である。

In addition, both the synchronous motor and the induction motor are provided with distributed winding of the armature winding for electromagnetic coupling in the stator, and are provided for inserting the winding in the laminated electromagnetic steel sheet. It is manufactured by incorporating a winding in the slot.
Therefore, in this situation, in the synchronous motor, after the winding is incorporated, the winding end is connected, and the end coil is shaped and fixed, so that the workability is poor, the process is long, and the work is damaged. Degradation of reliability such as dielectric breakdown during use due to, entanglement and interference between narrow slots and windings, or decrease in slot space factor (usually 50%) to improve workability of assembly work, extra The increase in cost due to the extension of the end coil, the decrease in efficiency and the decrease in output due to the increase in the resistance loss of the end coil part and the increase in leakage magnetic flux, etc. Moreover, mechanization of production was difficult, and when it was implemented, the equipment cost was large. Further, in the case of low voltage, medium-sized or large-sized devices, the winding wrinkles became larger and the workability was further deteriorated, resulting in a further significant cost increase. For this reason, the performance of the synchronous motor in the stator, downsizing, and productivity have been hindered.
In addition, when changing the number of poles in the conventional structure, the winding is changed. However, except for the case where the outer shape of the iron core is specially dealt with, the limit is usually eight. Conventional rotating electrical machines have very low efficiency at low speeds and small outputs, and 20 to 30% is common even with magnetic rotating electrical machines.

In order to achieve the above object, the present invention will be described in order of means for solving the problems.

Alternatively, a combination of a plurality of AC electromagnets, a combination of a plurality of permanent magnets in the rotor, and a stator as an induction motor in which an armature winding is arranged on a surface that is a cylindrical surface parallel to the rotation axis. It is constituted by an iron core, a rotor is constituted by a squirrel-cage derivative, and a permanent magnet type rotating electrical machine and an induction motor that are magnetically independent from each other are integrated into an integrated configuration.

It is characterized by being configured.

第3の発明は、永久磁石式回転電機および電動機または誘導電動機を同一軸にて駆動する一体構成とし、外部動力装置を誘導電動作用により起動させたのち、外部動力装置により永久磁石式回転電機を発電機として発電させる構成としたことを特徴とする。   According to a third aspect of the present invention, the permanent magnet type rotating electrical machine and the electric motor or the induction motor are integrally configured to be driven by the same shaft, and the external power device is started by induction motor action, and then the permanent magnet type rotating electrical machine is operated by the external power device. The power generator is configured to generate power.

第4の発明は、永久磁石式回転電機と電動機または誘導電動機を同一軸にて駆動する一体構成とし、外部動力装置を誘導電動作用により起動させたのち、永久磁石式回転電機さらには電動機を駆動したのち、必要に応じて永久磁石式回転電機を発電機として発電させる構成としたことを特徴とする。   According to a fourth aspect of the present invention, a permanent magnet type rotating electrical machine and an electric motor or an induction motor are integrally driven to drive on the same shaft, and after starting an external power unit by induction motor action, the permanent magnet type rotating electrical machine and further the motor are driven. After that, it is characterized in that a permanent magnet type rotating electrical machine is configured to generate electricity as a generator if necessary.

第5の発明は、外部動力装置をフライホイールとして使用し蓄電を行い、さらに必要時に発電を可能としたことを特徴とする。   The fifth invention is characterized in that an external power unit is used as a flywheel for power storage, and further power generation is possible when necessary.

第1の発明は、永久磁石式回転電機と誘導電動機とが一体的に形成された複合式回転電機の構成にある。回転電機としては、固定子においてはエンドコイルを伴わない集中巻きのボビン式巻線を回転軸と直交する面に電機子巻線として配し磁極鉄心とによって形成する直流または交流電磁石を複数個組み合わせて構成し、回転子においては永久磁石を複数個組み合わせて構成されている。誘導電動機としては、固定子においては回転軸と平行円筒面となる面に電機子巻線を配し磁極鉄心とによって構成し、固定子電機子巻線による1次導体の界磁に対して、回転子を2次かご形誘導体により構成されている。係る方法によって、永久磁石式回転電機の電機子巻線と誘導電動機の電機子巻線とは互いに本質的に磁気的に磁束面の結合は互いに直交し干渉しないように独立した構造に形成されている。且つ回転電機と誘導電動機の回転子を同一軸にて駆動する一体に構成されている複合式回転電機とされている。
この構成によれば、永久磁石式回転電機と誘導電動機起動時には、誘導電動機の固定子側の1次導体と、回転子側の2次かご形誘導体との間での磁気的作用により、回転子が回転を開始する。即ち誘導電動作用の原理で回転を開始する。こののち回転電機の固定子が作る磁界の回転速度である同期速度に回転子の回転速度が達すると、固定子側のボビン巻線による電機子巻線による電機子巻線による電機子巻線と、回転子側の永久磁石との間に生じる磁気的作用により、回転子が同期速度で回転する。即ち、同期電動作用の原理で回転子が回転するので、回転子の回転速度が安定する。
誘導電動機においては、回転電機のボビン式巻線による電機子巻線と固定子磁極鉄心とにより形成する回転磁界を永久磁石による磁界の阻害がなく、磁束が減らされずまたは乱されず、誘導電動機としての起動特性を良好にさせることができる。更に、すべり周波数での電磁力の脈動、外乱作用がなく同期引入れが安定する。
回転電機としては、誘導電動機による電機子巻線と固定子磁極鉄心とにより形成する回転磁界の干渉、影響がなく、永久磁石と固定子の距離を適切な位置に配置し、磁路・磁極構造の形成を確実にし、永久磁石が回転子の表面近傍に配置されトルクが大きくなる。
さらに、回転電機として、独立したボビン式巻線による電機子巻線と磁極鉄心とによって形成する直流または交流電磁石を複数個組み合わせて使われる固定子において、巻線は集中巻きであり、各相ごとに、シンプルな形成とし、巻線と磁極鉄心は独立しているために、出力容量調整、起動トルク調整及び効率アップ等の変更、調整は容易である。
ボビン式巻線による電機子巻線によって基本的にエンドコイルを持たない電磁結合を短い線で磁極鉄心に組み込み固定子を形成し、回転電機の性能、小型化、加工性、組立作業性等の生産性の強化を確実に図ることができる。
巻線組み込み後巻線端部を接続、エンドコイルの成形や固定等非常に複雑面倒な作業がなく、工程も短く、作業中の傷付き等による使用中の絶縁破壊等の信頼性の低下も無く、狭いスロットや巻線間の絡みや干渉は全く無く、また組線作業の作業性をよくする為のスロット占積率の低下も無く、エンドコイルの延長によるコスト増およびエンドコイル部の抵抗損の増加や漏洩磁束の増加等による効率低下や出力低下等が無い。
またシンプルな構造であるために、組立作業性がよく、生産の機械化が易しく、それを実施した場合の設備費も小額ですむ。また、磁極部や磁路部などに焼結材や積層構造を使用して、性能及び生産性を上げる構造を実現している。さらに鉄心部の多種少量生産や容量の大小に適用可能な分割鉄心や極数変更が磁極部のつけ方で自在に可能な鉄心構造を可能にしている。また、低電圧のみならず中型・大型機器の場合巻線の径は比較的小さくなり、作業性をよくして、さらにコスト安が実現可能となる。
また、極数の変更は特別に鉄心の外形を大きくせずに、8極以上の実現も可能である。
また、本発明の構造においては、超高温環境で使用される回転電機は周囲温度とコイルの温度上昇値を合せた温度で250度以上でも実現容易となっている。
一体の構成であるから回転軸受損失も少なく、小形化も容易である。
小形回転電機でも90%以上の効率が得られている。固定子と回転子の相互に必要な磁力を強化することにより性能の飛躍的向上、および安定性、製品の信頼性がえられる。
1st invention exists in the structure of the composite type rotary electric machine in which the permanent magnet type rotary electric machine and the induction motor were integrally formed. As a rotating electrical machine, a combination of a plurality of DC or AC electromagnets formed by a magnetic core with a concentrated bobbin-type winding without an end coil arranged on the surface orthogonal to the rotation axis as an armature winding. The rotor is configured by combining a plurality of permanent magnets. As an induction motor, in a stator, an armature winding is arranged on a surface that becomes a cylindrical surface parallel to a rotation axis, and is constituted by a magnetic core, and against the field of the primary conductor by the stator armature winding, The rotor is composed of a secondary cage derivative. By such a method, the armature winding of the permanent magnet type rotary electric machine and the armature winding of the induction motor are formed in an independent structure so as to be essentially magnetically coupled to each other so that the coupling of the magnetic flux surfaces is orthogonal to each other and does not interfere with each other. Yes. In addition, the rotary electric machine and the induction motor are configured as a combined rotary electric machine that is integrally configured to drive the rotor of the induction motor on the same axis.
According to this configuration, at the time of starting the permanent magnet type rotating electric machine and the induction motor, the rotor is caused by a magnetic action between the primary conductor on the stator side of the induction motor and the secondary cage derivative on the rotor side. Starts rotating. That is, the rotation starts on the principle of induction electric action. After that, when the rotational speed of the rotor reaches the synchronous speed that is the rotational speed of the magnetic field generated by the stator of the rotating electrical machine, the armature winding by the armature winding by the armature winding by the bobbin winding on the stator side The rotor rotates at a synchronous speed by a magnetic action generated between the rotor-side permanent magnets. That is, since the rotor rotates on the principle of synchronous electric action, the rotation speed of the rotor is stabilized.
In the induction motor, the rotating magnetic field formed by the armature winding by the bobbin-type winding of the rotating electrical machine and the stator magnetic core is not obstructed by the permanent magnet, the magnetic flux is not reduced or disturbed, and the induction motor The start-up characteristics can be improved. Further, there is no pulsation of electromagnetic force at the slip frequency and no disturbance effect, and the synchronous pull-in is stabilized.
As a rotating electrical machine, there is no interference and influence of the rotating magnetic field formed by the armature winding by the induction motor and the stator magnetic pole core, the distance between the permanent magnet and the stator is arranged at an appropriate position, and the magnetic path / magnetic pole structure The permanent magnet is arranged near the surface of the rotor, and the torque is increased.
Furthermore, as a rotating electric machine, in a stator that is used by combining a plurality of DC or AC electromagnets formed by armature windings and magnetic cores with independent bobbin windings, the windings are concentrated windings, and each phase In addition, since the winding and the magnetic core are independent, the change and adjustment such as output capacity adjustment, start-up torque adjustment and efficiency increase are easy.
By using armature windings with bobbin windings, electromagnetic couplings that basically do not have end coils are incorporated into magnetic pole cores with short wires to form stators, and the performance, miniaturization, workability, assembly workability, etc. It is possible to reliably enhance productivity.
There is no complicated work such as forming or fixing the end coil after connecting the winding end, and the process is short, and the reliability such as dielectric breakdown during use due to scratches during the work is also reduced. There is no entanglement or interference between narrow slots and windings, and there is no drop in the slot space factor to improve the workability of assembly work. There is no reduction in efficiency or output due to an increase in loss or an increase in leakage magnetic flux.
