Description

この発明は、運転状態に応じて電機子導体に流れる電流の振幅と位相が切換えられる回転電機に関するものである。 The present invention relates to a rotary electric machine in which the amplitude and phase of a current flowing through an armature conductor are switched according to an operating state.

従来、回転電機の電機子巻線の巻数や巻線間の接続方法を切換えることにより運転領域を拡大し、特性が向上した回転電機が提案されている。
例えば、特許文献１には、ｎ個の部分巻線より構成される電機子巻線の同相コイルの接続を直列と並列に切換えること、相コイル間の結線をＹ結線とΔ結線とに切替えることにより運転領域が拡大し、また特性が向上した誘導電動機が記載されている。 Conventionally, a rotary electric machine has been proposed in which the operating range is expanded and the characteristics are improved by switching the number of turns of the armature winding of the rotary electric machine and the connection method between the windings.
For example, in Patent Document 1, the connection of in-phase coils of an armature winding composed of n partial windings is switched in series and in parallel, and the connection between phase coils is switched between Y connection and Δ connection. Induction motors with expanded operating range and improved characteristics are described.

ところで、運転領域内において、高速域と低速域、高負荷域と低負荷域では回転電機に求められる特性が異なる。
例えば、低負荷域ではトルクリップルや電流リップルが出力トルクや入出力電流に比べて比較的大きくなり影響が顕著となるためリップルの小さな特性が求められるのに対して、高負荷域では温度の成立性等が求められる。
上記誘導電動機では、相コイルの巻数や直並列切換、Ｙ-Δ結線の変更等によって線間電圧ピーク値や相コイルの電流密度を変化させていたが、切換によって固定子と回転子とのギャップ磁束密度波形自体は変化しないために、トルクリップルや電流リップル等のギャップ磁束波形に起因する特性を変化させることはできなかった。 By the way, in the operating range, the characteristics required for the rotary electric machine are different between the high speed range and the low speed range, and the high load range and the low load range.
For example, in the low load range, the torque ripple and current ripple are relatively large compared to the output torque and input / output current, and the effect is significant. Therefore, a characteristic with small ripple is required, whereas in the high load range, the temperature is established. Gender is required.
In the above induction motor, the line voltage peak value and the current density of the phase coil are changed by changing the number of turns of the phase coil, series-parallel switching, Y-Δ connection, etc., but the gap between the stator and the rotor is changed by switching. Since the magnetic flux density waveform itself does not change, it is not possible to change the characteristics caused by the gap magnetic flux waveform such as torque ripple and current ripple.

一般に、分布巻は集中巻に比べて電機子の作るギャップ磁束分布を正弦波に近づけることができ、さらに短節巻は全節巻に比べてギャップ磁束分布を正弦波に近づけることができる。
このことから短節巻の巻線パターンを採用することによって集中巻の巻線パターンを採用した回転電機に比べてトルクリップルを低減しやすい。
一方で、短節巻は磁束利用率が低くトルクを得るのに電流を多く必要とするため高負荷での温度成立性が難しくなるという問題がある。
全節巻きもしくは短節巻きに巻装された分布巻巻線や集中巻巻線を用い、相コイルに通電する電流の振幅と位相を変えることによって他の磁束波形を再現することができれば上記課題を解決した回転電機を作ることができる。
しかしながら、実際には磁束の合成により相コイルが発生する磁束を相互に打消すような通電をする必要があるために、導体損失を発生させるのみでトルクを発生しないムダ導体が発生し効率が低下するという新たな問題を生じる。 In general, the distributed winding can bring the gap magnetic flux distribution created by the armature closer to the sine wave than the concentrated winding, and the short-node winding can bring the gap magnetic flux distribution closer to the sine wave than the all-node winding.
For this reason, it is easy to reduce the torque ripple by adopting the short-knot winding winding pattern as compared with the rotary electric machine adopting the centralized winding winding pattern.
On the other hand, the short winding has a problem that the magnetic flux utilization rate is low and a large amount of current is required to obtain torque, which makes it difficult to establish a temperature under a high load.
If it is possible to reproduce other magnetic flux waveforms by changing the amplitude and phase of the current energizing the phase coil using distributed winding windings or concentrated winding windings wound in full-node winding or short-node winding, the above problem It is possible to make a rotating electric machine that solves the problem.
However, in reality, since it is necessary to energize the magnetic fluxes generated by the phase coils by synthesizing the magnetic fluxes so as to mutually cancel each other, wasteful conductors that only generate conductor loss and do not generate torque are generated, and the efficiency is lowered. It raises a new problem of doing.

ここで、ムダ導体について簡単に説明する。
図８（ａ）、（ｂ）は、従来の全節巻、短節巻、集中巻を切替る構成を示す模式図であり、図８（ａ）はステータコア５１に巻装されたコイル５０を回転電機の軸線方向に沿って視たときの図、図８（ｂ）は図８（ａ）の回転電機を径方向に沿って視たときの図である。
図中矢印はコイル５０に流れる電流の向きを示している。
図８（ａ）、（ｂ）において、従来の全節巻，短節巻，集中巻を切替る構造では例えば集中巻のコイル５０がステータコア５１に巻きつけられている。
分布巻の磁束波形を作る際には、図８に示すように例えば２スロット離れた分布巻とする場合、間に挟まれるコイル５０を隣同士結ぶことで２スロット離れた位置のコイル５０を接続する。
この場合、同スロットに挿入された２つのコイル５０は互いに電流の向きが逆であるため互いに磁束を打ち消し合う。
従って、２スロット離れたコイル５０を結ぶ間のコイル５０は電流が通電されることによる導体損失を発生するものの有効な磁束を発生させない、所謂ムダ導体となる。 Here, the waste conductor will be briefly described.
8 (a) and 8 (b) are schematic views showing a configuration for switching between conventional full-knot winding, short-knot winding, and concentrated winding, and FIG. 8 (a) shows a coil 50 wound around a stator core 51. FIG. 8 (b) is a view when the rotary electric machine is viewed along the axial direction of the rotary electric machine, and FIG. 8 (b) is a view when the rotary electric machine of FIG. 8 (a) is viewed along the radial direction.
The arrows in the figure indicate the direction of the current flowing through the coil 50.
In FIGS. 8A and 8B, in the conventional structure for switching between full-knot winding, short-knot winding, and concentrated winding, for example, a concentrated winding coil 50 is wound around the stator core 51.
When creating a magnetic flux waveform of a distributed winding, for example, when the distributed winding is separated by 2 slots as shown in FIG. 8, the coils 50 sandwiched between them are connected to each other to connect the coils 50 at positions 2 slots apart. To do.
In this case, the two coils 50 inserted in the same slot cancel each other's magnetic flux because the directions of the currents are opposite to each other.
Therefore, the coil 50 between connecting the coils 50 separated by two slots is a so-called waste conductor that causes a conductor loss due to the current being applied but does not generate an effective magnetic flux.

この発明は、上記課題を解決するものであり、運転領域の拡大と共に上記ギャップ磁束密度波形を任意に操作することで、各運転ポイントに求められる好適な磁束波形を形成し、かつ上記のようなムダ導体による損失のない低損失な回転電機を提供するものである。 The present invention solves the above problems, and by arbitrarily manipulating the gap magnetic flux density waveform while expanding the operating region, a suitable magnetic flux waveform required for each operating point can be formed, and as described above. It provides a low-loss rotary electric machine without loss due to a waste conductor.

Further, when all the four switches 26, 30, 29, and 28 of the H-bridge circuit are turned off, the conductor bar 17 is disconnected from the DC power supply 27 and no current flows.
In this way, the control device switches the switches 26, 30, 29, and 28 on and off, and changes the ratio of the on-time and the off-time, respectively, so that each conductor bar 17 has an arbitrary amplitude and phase. The current can be energized.

このように各導体バー１７に通電することで、モータ１は、６相の全節巻、短節巻、集中巻の駆動をそれぞれ行うことができる。 By energizing each conductor bar 17 in this way, the motor 1 can drive the six-phase full-node winding, short-node winding, and concentrated winding, respectively.

次に、３相モータ１の動作について説明する。
３相についても同様に、Ｕ＋，Ｖ＋，Ｗ＋をそれぞれ振幅が等しく位相が１２０度ずつ順番にずれた３相交流の相とし、Ｕ−，Ｖ−，Ｗ−はそれぞれＵ＋，Ｖ＋，Ｗ＋に対して位相が反転した状態を表すものとする。
モータ１が全節巻の駆動を行なうには、通電する各導体バー１７に次のように電流位相を調節する。
即ち、番号ａ，ｂ，ｃ，ｄの各導体バー１７にＵ＋の相、番号ｅ，ｆ，ｇ，ｈの各導体バー１７にＶ＋の相、番号ｉ，ｊ，ｋ，ｌの各導体バー１７にＷ＋の相、番号ｍ，ｎ，ｏ，ｐの各導体バー１７にＵ−の相、番号ｑ，ｒ，ｓ，ｔの各導体バー１７にＶ−の相、番号ｕ，ｖ，ｗ，ｘの各導体バー１７にＷ−の相関係となるように通電する電流位相を調整することで、８極４８スロットの３相全節巻の電機子磁束を構成することができる。 Next, the operation of the three-phase motor 1 will be described.
Similarly for the three phases, U +, V +, and W + are regarded as three-phase AC phases having the same amplitude and the phases are shifted by 120 degrees in order, and U−, V−, and W− are relative to U +, V +, and W +, respectively. It is assumed that the phase is inverted.
In order for the motor 1 to drive all the nodes, the current phase of each of the conducting bar 17s is adjusted as follows.
That is, each conductor bar 17 of numbers a, b, c, d has a U + phase, each conductor bar 17 of numbers e, f, g, h has a V + phase, and each conductor bar of numbers i, j, k, l has. 17 is the W + phase, each conductor bar 17 with numbers m, n, o, p is the U- phase, and each conductor bar 17 with numbers q, r, s, t is the V- phase, numbers u, v, w. By adjusting the current phase in which the conductor bars 17 of, and x are energized so as to have a W-phase relationship, an armature magnetic flux of three-phase full-node winding of eight poles and 48 slots can be formed.

また、モータ１が集中巻の駆動を行なうには、通電する各導体バー１７に次のように電流位相を調節する。
即ち、番号ａ，ｂの各導体バー１７にＵ＋の相、番号ｃ，ｄの各導体バー１７にＵ−の相、番号ｅ，ｆの各導体バー１７にＶ＋の相、番号ｇ，ｈの各導体バー１７にＶ−の相、番号ｉ，ｊの各導体バー１７にＷ＋の相、番号ｋ，ｌの各導体バー１７にＷ−の相、番号ｍ，ｎの各導体バー１７にＵ−の相、番号ｏ，ｐの各導体バー１７にＵ＋の相、番号ｑ，ｒの各導体バー１７にＶ−の相、番号ｓ，ｔの各導体バー１７にＶ＋の相、番号ｕ，ｖの各導体バー１７にＷ−の相、番号ｗ，ｘの各導体バー１７にＷ＋の相となるように通電する電流位相を調整することで、８極４８スロットの３相集中巻の電機子磁束を構成することができる。 Further, in order for the motor 1 to drive the centralized winding, the current phase of each of the conductor bars 17 to be energized is adjusted as follows.
That is, the conductor bars 17 of numbers a and b have a U + phase, the conductor bars 17 of numbers c and d have a U− phase, and the conductor bars 17 of numbers e and f have a V + phase, and the conductor bars 17 have numbers g and h. Each conductor bar 17 has a V- phase, each of the conductor bars 17 of numbers i and j has a W + phase, each of the conductor bars 17 of numbers k and l has a phase of W-, and each of the conductor bars 17 of numbers m and n has a U. -Phase, U + phase in each conductor bar 17 of numbers o and p, V- phase in each conductor bar 17 of numbers q and r, V + phase in each conductor bar 17 of numbers s and t, number u, By adjusting the current phase that energizes each conductor bar 17 of v so that it becomes the W- phase and each conductor bar 17 of numbers w and x becomes the W + phase, a three-phase concentrated winding electric machine with 8 poles and 48 slots A child magnetic flux can be formed.

このように各導体バー１７に通電することで、モータ１は、３相の全節巻，集中巻の駆動をそれぞれ行うことができる。 By energizing each conductor bar 17 in this way, the motor 1 can drive the three-phase full-node winding and the centralized winding, respectively.

この実施の形態のモータ１では、第１の正極側スイッチ２６、第２の負極側スイッチ２８、第１の負極側スイッチ２９及び第２の正極側スイッチ３０の動作を制御装置により制御することで、各導体バー１７に流れる電流の振幅及び位相は、各導体バー１７毎に制御され、ステータ９とロータ８との間のギャップ磁束密度波形が任意に調整され、各運転ポイントに求められる好適な磁束波形を形成し、ムダ導体による損失なく全節巻、短節巻、集中巻の駆動を行うことができる。
従って、運転領域の拡大のみならずトルクリップル等の駆動特性も向上させることができる。 In the motor 1 of this embodiment, the operation of the first positive electrode side switch 26, the second negative electrode side switch 28, the first negative electrode side switch 29, and the second positive electrode side switch 30 is controlled by the control device. The amplitude and phase of the current flowing through each conductor bar 17 are controlled for each conductor bar 17, and the gap magnetic flux density waveform between the stator 9 and the rotor 8 is arbitrarily adjusted, which is suitable for each operating point. A magnetic flux waveform can be formed, and all-node winding, short-node winding, and concentrated winding can be driven without loss due to waste conductors.
Therefore, not only the operating range can be expanded but also the driving characteristics such as torque ripple can be improved.

また，電機子は、２次元断面上の全導体バー１７に流れる電流の振幅と位相を直接的に制御することができるため、ステータコア１５に対し導線が巻きつけられたものを電流のベクトル合成により実現するものと異なり、余分な電流を流す必要が無く損失を低減することができる。 Further, since the armature can directly control the amplitude and phase of the current flowing through all the conductor bars 17 on the two-dimensional cross section, the conductor is wound around the stator core 15 by vector synthesis of the current. Unlike what is realized, it is not necessary to pass an extra current and the loss can be reduced.

また、ロータ８は、軸線方向に延びた磁石スロット２０に永久磁石２１が収納されたロータコア１９を有し、複数の導体バー１７のうち、図４において反時計方向に回転するロータ８の回転方向の遅れ側の永久磁石２１の端部に対向する導体バー１７（図４において、番号ｍ，ｎ，ｏ，ｐ）に流れる電流の振幅は、通常正弦波電流を流した際の電流振幅と比較して小さくなるように制御装置により調整されている。そして、他の位置の導体バー１７に流れる電流の振幅を大きくすることで出力するトルクが保たれる。
従って、永久磁石２１がもっとも減磁しやすい位置の励磁を弱めることで同じ磁石量に対してトルクを向上させることができる。 Further, the rotor 8 has a rotor core 19 in which a permanent magnet 21 is housed in a magnet slot 20 extending in the axial direction, and among a plurality of conductor bars 17, the rotation direction of the rotor 8 rotating counterclockwise in FIG. The amplitude of the current flowing through the conductor bar 17 (numbers m, n, o, p in FIG. 4) facing the end of the permanent magnet 21 on the lagging side is compared with the current amplitude when a normal sinusoidal current is passed. It is adjusted by the control device so that it becomes smaller. Then, the output torque is maintained by increasing the amplitude of the current flowing through the conductor bar 17 at another position.
Therefore, the torque can be improved for the same amount of magnet by weakening the excitation at the position where the permanent magnet 21 is most likely to be demagnetized.

なお、各導体バー１７に流す電流を調整して、各スイッチ２６，３０，２９，２８を制御する制御装置を１つのスイッチ２６，３０，２９，２８につき一つ設けられているが、第１の正極側スイッチ２６と第１の負極側スイッチ２９、第２の負極側スイッチ２８と第２の正極側スイッチ３０とは常に同期してオン，オフを行うので、第１の正極側スイッチ２６と第１の負極側スイッチ２９とを同じ一つの制御装置で制御し、第２の負極側スイッチ２８と第２の正極側スイッチ３０とを同じ一つの制御装置で制御してもよい。
このようにすると制御装置の数を半分にすることができる。
さらに、上記構成のモータ１は、上述の通り１極対対称で導体バー１７に通電される。そこで１極対分ずつずれた位置にあるスイッチ２６，３０，２９，２８を１つの制御装置で制御してもよい。このようにすると制御装置の数を４分の１にすることができる。 A control device for controlling each of the switches 26, 30, 29, 28 by adjusting the current flowing through each conductor bar 17 is provided for each switch 26, 30, 29, 28.

In this way, the number of control devices can be halved.
Further, the motor 1 having the above configuration is energized to the conductor bar 17 in a one-pole pair symmetry as described above. Therefore, the switches 26, 30, 29, and 28 located at positions offset by one pole pair may be controlled by one control device. In this way, the number of control devices can be reduced to one-fourth.

なお、上記実施の形態のモータ１では、各ステータスロット１６に挿入される導体バー１７は２つずつであったが、２つ以上の複数の導体バー１７を挿入してもよい。

この場合にも各相のインダクタンスのばらつきを小さくすることができる。 In the motor 1 of the above embodiment, two conductor bars 17 are inserted into each status lot 16, but two or more conductor bars 17 may be inserted.
In this way, the variation in the inductance of each phase can be reduced.

In this case as well, the variation in inductance of each phase can be reduced.

また、上記実施の形態のモータ１では、直流電源２７は、各Ｈブリッジ回路に対して１つずつ配置されているが、１極対ずつずれた位置にある導体バー１７が１つの直流電源２７を共用するように配置されてもよい。
このようにすれば直流電源２７の数を減らすことができる。 Further, in the motor 1 of the above embodiment, one DC power supply 27 is arranged for each H-bridge circuit, but one DC power supply 27 has a conductor bar 17 at a position deviated by one pole pair. May be arranged to share.

また、各ステータスロット１６内では、導体バー１７Ａにモールド成形されたインシュレータ１８が１つになるため、ステータスロット１６内の導体バー１７Ａの占積率が向上し高効率化を図ることができる。 In the motor 1 according to the second embodiment, each conductor bar 17A is energized by combining the currents of the two conductor bars 17 inserted in the status lot 16 of the first embodiment.
By doing so, the number of DC power supplies 27, the number of switches 26, 30, 29, 28, and the number of control devices can be halved, so that the size can be reduced.
Further, since the insulator 18 molded into the conductor bar 17A is one in each status lot 16, the space factor of the conductor bar 17A in the status lot 16 can be improved and the efficiency can be improved.
