Abstract
In order to improve performance and efficiency of a motor and a generator using a magnet and an electric magnet, the magnetic flux at the void portion is increased by adjusting the structure, dimensions, arrangement of the magnet and the iron core, thereby obtaining a desired rotary electric machine. In order to increase the magnetic flux in the void potion between a rotor and a stator so as to improve the performance and the efficiency of the motor and the generator using magnets as rotary electric machines, a radial or a ring-shaped magnet is arranged on the rotor and a magnet and a winding for radially intensifying the magnetic pole are arranged at the rear end of the magnetic pole. This intensifies the magnetic field in the void at the rear end of the magnetic pole of the rotor during synchronized rotation, maintains the relative position with respect to the stator magnetic pole during the rotation, and additionally increases the rotation drive force by the magnetic pole of the stator facing the front and back of the rear end of the magnetic pole of the rotor so as to constantly obtain a strong suction and repelling force. In a generator, a terminal voltage is kept almost constant even when excessive load is applied. In a motor, a reverse terminal voltage is kept almost constant.

In this patent, in an electric motor, magnets are arranged in a ring shape.

実施例 1 Example 1
[0033] 本発明の実施例を以下説明する。 [0033] Examples of the present invention will be described below.
[0034] 本発明の実施例 1、実施例 2、実施例 3、実施例 4、実施例 5の回転電機 1を同時に 図 1に示す。 21、 22、 23、 24は回転子、 3は固定子、 15は回転軸、 16は巻き線を示 す。 [0034] FIG. 1 shows the rotating electrical machine 1 of Example 1, Example 2, Example 3, Example 4, Example 5, and Example 5 of the present invention at the same time. 21, 22, 23 and 24 are rotors, 3 is a stator, 15 is a rotating shaft, and 16 is a winding.
本発明の実施例 1を図 2A及び図 2Bに示す。 21は回転子、 41は回転子 21の電磁 鋼板カゝらなる鉄心の磁極、 5、 51、 52は回転子 21の磁石を示す。磁極 41には放射
状に磁石 5、 51を配置し、円周部にはリング状磁石 52を配置する構成となっている。 さらに磁極後端部 8には放射状に磁極を強化形成する磁石 51と巻き線 61を配し、 磁極後端部の放射方向の磁界を強化すると同時に巻き線による調整用の電磁石に て僅かな電流にて磁界を制御できるようにして!/、る。力かる構造配置にて付カ卩的駆動 力により、過負荷状態にても電圧を増減させ、いかなる負荷状態にても最高の運転 状態を実現できる。この場合、磁石や巻き線単独でも組み合わせ同様に実現可能で ある。 6は溝を示し、 7は取付け穴を示す。 Example 1 of the present invention is shown in FIGS. 2A and 2B. Reference numeral 21 denotes a rotor, 41 denotes a magnetic pole of an iron core made of an electromagnetic steel plate of the rotor 21, and 5, 51 and 52 denote magnets of the rotor 21. Radiation to magnetic pole 41 The magnets 5 and 51 are arranged in the shape of a ring, and the ring-shaped magnet 52 is arranged around the circumference. In addition, the rear end 8 of the magnetic pole is provided with magnets 51 and windings 61 that radially strengthen the magnetic poles, and the magnetic field in the radial direction at the rear end of the magnetic poles is strengthened. To be able to control the magnetic field! With a powerful structural arrangement, it is possible to increase or decrease the voltage even in an overload condition and to achieve the best operating condition in any load condition with the additional driving force. In this case, a magnet or winding alone can be realized in the same way as a combination. 6 indicates a groove, and 7 indicates a mounting hole.
図 2Bは磁極後端部 8に巻き線 6 lbのみにて実施した例を示している。 4 lbはこの 例の場合の磁極を示す。 FIG. 2B shows an example in which only 6 lb of winding is applied to the rear end 8 of the magnetic pole. 4 lb indicates the magnetic pole in this example.
参考までに図 3は従来の放射状に磁石を設けた回転子の形状の一例を示す。 回転電機 1が発電機作用または電動機作用において、固定子 3と回転子 21とが同 極 (または異極)が主たる位置の場合は反発(引込み)の作用があり、同時に隣接す る固定子 3と回転子 21とが異極の一部の位置において引込み (反発)作用があり、固 定子 3と回転子 21との相対的作用によるつながりが良くなる。これを同期速度で回し た場合、回転子磁極後端部 8と磁極 41と対畤する固定子磁極で常時吸弓 I力が働き 、更に後方の固定子磁極とは常時反発力を発生させることができ、回転電機 1の駆 動力を付加的に発生させることができ、いかなる負荷状態にても発電機の端子電圧 や電動機の逆起電力をほぼ一定に保ち、性能向上を図り、トルクのコギング現象を 減らし、振動を抑制する効果が得られる。 For reference, Fig. 3 shows an example of the shape of a conventional rotor provided with radial magnets. When the rotating electrical machine 1 is in the generator action or the motor action, the stator 3 and the rotor 21 are repulsive (retracted) when the same polarity (or different polarity) is the main position. And the rotor 21 have a retraction (repulsion) action at some positions of different polarity, and the relative action between the stator 3 and the rotor 21 is improved. When this is rotated at the synchronous speed, the arch I force always acts on the stator magnetic pole that faces the rotor magnetic pole rear end 8 and the magnetic pole 41, and the rear stator magnetic pole always generates a repulsive force. It is possible to generate additional drive power for the rotating electrical machine 1, maintain the generator terminal voltage and the back electromotive force of the motor almost constant under any load conditions, improve performance, and torque cogging. This reduces the phenomenon and suppresses vibration.
実施例 2 Example 2
本発明の実施例 2を図 4に示す。 22は回転子、 42は回転子 22の電磁鋼板力もな る鉄心の磁極、 5は回転子 22の磁石を示す。さらに、磁極 42には放射状に磁石 5、 5 4を配置する形状とするとともにリング状に磁石 52, 53を配置する形状とし、さらに磁 極 42に溝 11を設けてある。 A second embodiment of the present invention is shown in FIG. 22 is a rotor, 42 is a magnetic pole of an iron core that also serves as an electromagnetic steel plate force of the rotor 22, and 5 is a magnet of the rotor 22. Further, the magnetic pole 42 has a shape in which the magnets 5 and 54 are arranged radially and a shape in which the magnets 52 and 53 are arranged in a ring shape, and the groove 11 is provided in the magnetic pole 42.
参考までに図 5は従来のリング状に磁石を設けた回転子の形状を示す。 For reference, Fig. 5 shows the shape of a conventional rotor with a magnet in a ring shape.
該回転子 22のリング状の磁石 52、 53は磁束を直接該回転子 22の磁石 52、 53に 戻らな 、ように該磁石 52、 53の周辺の溝 11には空隙または非磁性体部を設ける。 係る構成によって、回転子 22と固定子 3との空隙部の磁束の大幅な増加を図ってい
る。 The ring-shaped magnets 52 and 53 of the rotor 22 do not directly return the magnetic flux to the magnets 52 and 53 of the rotor 22, so that the grooves 11 around the magnets 52 and 53 have a gap or a non-magnetic part. Provide. With this configuration, the magnetic flux in the gap between the rotor 22 and the stator 3 is significantly increased. The
[0036] さらに、磁石 5は相対する隣の磁石に対して同極で対面して設置されている。回転 子 22の磁極 42は、例えば 4極の場合、 90度の角度の等分配置でなく 3極は一極ず つ 87〜93度の角度ピッチとしてある。残りの一極は 99から 81度として配置されてい る。一方の固定子 3の磁極はこの 4極の場合 90度に等分割されている。従って、電磁 的結合力もなる固定子 3の磁極に対して、相対的に位置を偏位させ回転子の極巾を 広くしている。 [0036] Furthermore, the magnet 5 is installed facing the adjacent magnet with the same polarity. For example, in the case of four poles, the magnetic poles 42 of the rotor 22 are not evenly arranged at an angle of 90 degrees, but the three poles have an angular pitch of 87 to 93 degrees per pole. The remaining pole is located at 99 to 81 degrees. The magnetic pole of one stator 3 is equally divided into 90 degrees in the case of these four poles. Therefore, the position of the rotor 3 is increased relative to the magnetic pole of the stator 3 that also has an electromagnetic coupling force, thereby widening the rotor width.
係る構成にすることによって、これを同期速度で回した場合、回転子磁極後端部 8 の放射磁界を磁石 54で強化した磁極 42と対畤する固定子磁極で回転中常時吸引 力が働き、更に後方の固定子磁極とは常時反発力を発生させることができ、回転電 機 1の駆動力を付加的に発生させ、過負荷状態においても発電機の端子電圧ゃ電 動機の逆起電力の低下を防ぎ、性能向上を図り、トルクのコギング現象を減らし、振 動を抑制する効果が得られる。 With this configuration, when this is rotated at a synchronous speed, the attraction force always works during rotation with the stator magnetic pole opposed to the magnetic pole 42 strengthened by the magnet 54 with the radiated magnetic field of the rotor magnetic pole rear end 8. In addition, a repulsive force can always be generated from the rear stator magnetic pole, which additionally generates the driving force of the rotating electric machine 1 and the terminal voltage of the generator even if it is overloaded. The effect is to prevent the decrease, improve the performance, reduce the cogging phenomenon of torque, and suppress the vibration.
実施例 3 Example 3
[0037] 本発明の実施例 3を図 6A及び図 6Bに示す。 23は 4極の回転子、 43は回転子 23 の電磁鋼板からなる鉄心の磁極を示す。 [0037] Embodiment 3 of the present invention is shown in FIGS. 6A and 6B. Reference numeral 23 denotes a 4-pole rotor, and 43 denotes a magnetic pole of an iron core made of a magnetic steel plate of the rotor 23.
図 6Aにおいて、回転子 23の磁極 43には、放射状に磁石 5、 54を配置し、リング状 に磁石群 52、 53を配置し、磁石 52、 53の周辺の空間 11には空隙または非磁性体 部が設けられている。 In FIG. 6A, magnets 5 and 54 are arranged radially on magnetic pole 43 of rotor 23, magnet groups 52 and 53 are arranged in a ring shape, and space 11 around magnets 52 and 53 is void or nonmagnetic. Body part is provided.
本構成は磁石のみで磁極 43を構成して ヽる例である。この磁極 43は固定子磁極 の巾より広く構成すると同時に、後端部に強力な磁界を形成する磁石 54を直接配置 して、回転子 23と固定子 3との空隙部の磁束の大幅な増加を図るとともに、回転子 2 3と固定子 3の磁極間の結合を偏位、一部重なりを形成している。 This configuration is an example in which the magnetic pole 43 is composed of only magnets. This magnetic pole 43 is made wider than the width of the stator magnetic pole, and at the same time, a magnet 54 that forms a strong magnetic field is directly arranged at the rear end, so that the magnetic flux in the gap between the rotor 23 and the stator 3 is greatly increased. In addition, the coupling between the magnetic poles of the rotor 2 3 and the stator 3 is deviated and partly overlapped.
これを固定子の磁極巾を少なくすることを併用すると、より効果的であることは明ら かである。 It is clear that it is more effective to combine this with reducing the magnetic pole width of the stator.
係る構成にすることによって、これを同期速度で回転した場合、回転子磁極後端部 8と磁極 43と対畤する固定子磁極で常時吸引力が働き、更に後方の固定子磁極と は常時反発力を発生させることができ、回転電機 1の駆動力を付加的、飛躍的に発
生させ、過負荷状態においても発電機の端子電圧や電動機の逆起電力の低下を防 ぎ、性能向上を図り、トルクのコギング現象を減らし、振動を抑制する効果が得られる 図 6Bは図 6Aの磁石 54にて形成している回転子磁極 43の後端部 8の磁界をより強 化するために専用の独立した鉄心 23で磁石群 52、 53のうち一部たとえば磁石 53を 除去したり、弱い磁石と入れ替えたりして構成されている。図 6Aの鉄心 23と組み合 わせて軸方向に種々編成することにより、同期回転時の付加的駆動力を調整し、過 負荷状態においても発電機の端子電圧や電動機の逆起電力の低下を防ぎ、性能向 上を図り、トルクのコギング現象を減らし、振動を抑制する効果が得られる。 With this configuration, when this is rotated at a synchronous speed, an attractive force is always exerted on the stator magnetic pole facing the rotor magnetic pole rear end 8 and the magnetic pole 43, and the stator magnetic pole at the rear is always repelled. Force can be generated, and the driving force of the rotating electrical machine 1 can be additionally and dramatically increased. Even in an overload condition, the terminal voltage of the generator and the back electromotive force of the motor can be prevented from decreasing, performance can be improved, torque cogging can be reduced, and vibration can be suppressed. In order to further strengthen the magnetic field at the rear end 8 of the rotor magnetic pole 43 formed by the magnet 54 of the magnet 54, a part of the magnet group 52, 53, for example, the magnet 53 is removed with a dedicated independent iron core 23. It is configured by replacing with weak magnets. In combination with the core 23 in Fig. 6A, various knitting in the axial direction adjusts the additional driving force during synchronous rotation and reduces the terminal voltage of the generator and the back electromotive force of the motor even in an overload condition. It can prevent, improve performance, reduce torque cogging phenomenon, and suppress vibration.
実施例 4 Example 4
本発明の実施例 4を図 7、図 8に示す。 1は回転電機、 24、 24a、 24bは回転子、 3 は固定子、 44は回転子 24a、 24bの電磁鋼板カゝらなる鉄心の磁極を示す。回転電機 1において、磁石 5、 52、 53、 54力らなる回転子 24における磁石 5、 52、 53を挿人 する上で、巻き線 16の電磁結合による鉄心力もなる固定子 3の軸方向の長さより長い 部分の磁石 5、 52、 53からなる回転子 24の「はみ出し部分」 24aにおいては放射状 の磁石 5とリング状の磁石 52、 53の相対する内側を同極とし、電磁結合による鉄心か らなる固定子 3の軸方向の長さより短い部分の磁石 5、 52、 53からなる回転子 24の「 はみ出さない部分」 24bにおいては放射状の磁石 5とリング状の磁石 52、 53との相 対する内側を異極とした構成とされている。係る構成により、回転子 24の「はみ出し 部分」 24aの磁束は矢印の方向となり、回転子 24の「はみ出さない部分」 24bの磁束 は矢印の方向となっている。従って回転子 24の「はみ出し部分」 24aの磁束と「はみ 出さない部分」 24bの磁束は重畳される。係る構成の結果、「はみ出し部分」 24aの長 さにほぼ比例して回転子 24と固定子 3の空隙部の磁束の大幅な増加を図ることを可 能とすると同時に、磁極後端部 8の放射方向の磁界強化に設けている磁石 54のは み出し部は磁界の方向を軸方向にすることにより、固定子と対畤する磁極後端部 8の 磁界をより一層強化し、回転電機 1の性能向上を大幅に図り、過負荷状態においても 発電機の端子電圧や電動機の逆起電力の低下を強固に防ぎ、トルクのコギング現象 を減らし、振動を抑制する効果が得られる。この結果、回転電機 1は小型の電動機で
も付カ卩的効率アップで 3〜5%が可能で、 95〜98%の高効率を得ている。また同出 力容量の回転電機 1の場合従来に比較し、より一層小型化が図られうる。 Embodiment 4 of the present invention is shown in FIGS. 1 is a rotating electrical machine, 24, 24a and 24b are rotors, 3 is a stator, 44 is a magnetic pole of an iron core made up of electromagnetic steel plates of the rotors 24a and 24b. In the rotating electrical machine 1, when inserting the magnets 5, 52, 53 in the rotor 24 having magnets 5, 52, 53, 54, the axial direction of the stator 3, which also has iron core force due to electromagnetic coupling of the winding 16, In the `` protruding part '' 24a of the rotor 24 consisting of the magnets 5, 52, 53 longer than the length, the opposite inner sides of the radial magnet 5 and the ring-shaped magnets 52, 53 have the same polarity, The portion of the rotor 24 consisting of magnets 5, 52, 53 that is shorter than the axial length of the stator 3 that does not protrude is the phase between the radial magnet 5 and the ring-shaped magnets 52, 53. On the other hand, the inner side is a different polarity. With this configuration, the magnetic flux of the “protruding portion” 24a of the rotor 24 is in the direction of the arrow, and the magnetic flux of the “non-extruding portion” 24b of the rotor 24 is in the direction of the arrow. Therefore, the magnetic flux of the “protruding part” 24a of the rotor 24 and the magnetic flux of the “part not protruding” 24b are superimposed. As a result of this configuration, the magnetic flux in the gap between the rotor 24 and the stator 3 can be increased substantially in proportion to the length of the “protruding portion” 24a, and at the same time, the magnetic pole rear end 8 The protruding part of the magnet 54 provided to strengthen the magnetic field in the radial direction makes the magnetic field direction the axial direction, thereby further strengthening the magnetic field of the magnetic pole rear end 8 facing the stator. As a result, the generator terminal voltage and the back electromotive force of the motor are strongly prevented even under overload conditions, and the torque cogging phenomenon is reduced and vibration is suppressed. As a result, the rotating electrical machine 1 is a small electric motor. In addition, it is possible to increase 3 to 5% by increasing the efficiency, and achieve a high efficiency of 95 to 98%. Further, in the case of the rotating electrical machine 1 having the same output capacity, the size can be further reduced as compared with the conventional case.
図 9は本発明の発電機の負荷電圧特性を示す。在来の磁石式発電機は無負荷状 態の端子電圧が最高で、負荷が増加するに従い徐々に低下していき、過負荷状態 になると電圧低下が大きくなり、性能の低下が顕著となる。一方本案の発電機は無負 荷の端子電圧を最低に、負荷が増加するに従い逆に増加し、過負荷状態になっても 電圧が維持され、性能を最高の状態に保つことが示されている。本特性は磁石のみ の回転子を用いた発電機の例であるが、磁極後端部に巻き線による電磁石を併用 することにより、僅かな電流で細かい電圧調整が可能となることは言うまでもない。 実施例 5 FIG. 9 shows the load voltage characteristics of the generator of the present invention. Conventional magnet generators have the highest terminal voltage in the no-load state, and gradually decrease as the load increases. In an overload state, the voltage drop increases and the performance decreases significantly. The proposed generator, on the other hand, has been shown to keep the terminal voltage at no load at the lowest level and increase as the load increases, maintaining the voltage even in an overload condition and maintaining the highest performance. Yes. This characteristic is an example of a generator using a rotor with only a magnet, but it goes without saying that fine voltage adjustment can be achieved with a small amount of current by using a coiled electromagnet at the rear end of the magnetic pole. Example 5
[0039] 本発明の実施例 5を図 10A、図 10Bに示す。図 10Aは発電機の負荷抵抗 Lと並列 に容量性抵抗 C 1を接続することにより、負荷状態で発電機卷線 16に流れる電流の 位相を発電電圧よりさらに進めることにより、付加的駆動力を増大し、過負荷時の電 圧低下防止をより一層増大したものである。また、外部の C1の容量を変えるのみで 発電機の容量調整も可能となる。 Example 5 of the present invention is shown in FIGS. 10A and 10B. Figure 10A shows the additional driving force by connecting the capacitive resistor C1 in parallel with the load resistance L of the generator, and by further advancing the phase of the current flowing through the generator winding 16 in the load state above the generated voltage. This increases the prevention of voltage drop during overload. In addition, the generator capacity can be adjusted simply by changing the capacity of the external C1.
図 10Bは電動機の特性改善に卷線 16bと並列に容量性抵抗 C2を、直列に容量性 抵抗 C3を接続し、特性改善を図った例を示している。 C2は電源の正弦波波形に電 動機の卷線に発生する逆起電力の波形を合わせるため、発生した高調波成分をカツ トするためのものである。また、 C3は電動機の固定子卷線中を流れる電流の位相を 電源電圧に対して進め、過負荷状態でも磁極後端部での付加的駆動力を増大し、 卷線中の逆起電力を増大し性能低下を防止する効果を有する。 Fig. 10B shows an example of improving the characteristics of the motor by improving the characteristics by connecting a capacitive resistor C2 in parallel with the feeder line 16b and a capacitive resistor C3 in series. C2 is used to cut the generated harmonic components in order to match the sine wave waveform of the power supply with the waveform of the back electromotive force generated on the generator shoreline. C3 also advances the phase of the current flowing in the stator winding of the motor with respect to the power supply voltage, increasing the additional driving force at the rear end of the magnetic pole even in an overload condition, and reducing the back electromotive force in the winding. It has the effect of increasing and preventing performance degradation.
