つぎに、始動機兼発電機Aの起動方法を説明する。Next, a method for starting the starter/generator A will be explained.
(1)バッテリーBの電力を三相電力変換器6により3
0Hzの三相交流にして三相コイル32に通電する。こ
れにより1100rpの回転磁界が生じる。尚、回転子
用励磁巻線5には通電しないので、通常の同期機の起動
時のような直流NS極は形成されない(同期トルクゼロ
)6
(2)回転子4はアルミで鋳込まれているので渦電流ト
ルクか生じ回転し始める。(1) Power from battery B is converted to 3 by three-phase power converter 6.
The three-phase coil 32 is energized with three-phase alternating current of 0 Hz. This produces a rotating magnetic field of 1100 rpm. In addition, since the rotor excitation winding 5 is not energized, the DC NS poles are not formed as in the case of starting a normal synchronous machine (synchronous torque is zero) 6 (2) The rotor 4 is cast from aluminum. This causes eddy current torque and starts to rotate.
(3)回転子4が10rpm 〜2Orpmに達すると
、電機子巻線3が発生する回転磁界の位置を、回転子4
の磁極位置と電気角π/2(rad)に合わせるように
、前記ホール素子で検出して電機子巻線3に流す三相交
流の周波数を調整するとともに、回転子用励磁巻線5に
直流電流を流し、回転子4を同期引入れする。(3) When the rotor 4 reaches 10 rpm to 2 Orpm, the position of the rotating magnetic field generated by the armature winding 3 is
The frequency of the three-phase AC detected by the Hall element and applied to the armature winding 3 is adjusted so as to match the magnetic pole position and electrical angle π/2 (rad), and the DC current is applied to the rotor excitation winding 5. A current is applied and the rotor 4 is synchronously pulled in.
(4)始動機兼発電機Aは、同期電動機として高い駆動
トルクを発生する。三相交流の周波数を高めて行く(最
大1kHz程度)ことにより、エンジン回転は完爆回転
まで上昇し、連爆に至る。(4) The starter/generator A generates high driving torque as a synchronous motor. By increasing the frequency of the three-phase alternating current (up to about 1 kHz), the engine speed increases to full explosion speed, resulting in repeated explosions.
つぎに、始動機兼発電機Aの作用効果を述べる。Next, the effects of the starter/generator A will be described.
(あ)起動の瞬間から機関完爆に至るまで、30Hz以
上の交流駆動である。このため、コイルリアクタンスの
作用により過大電流が流れることもないので、三相電力
変換器6のパワートランジスタの定格を小さくできる。(A) From the moment of startup to the complete engine explosion, the engine is driven by AC at 30Hz or higher. Therefore, no excessive current flows due to the action of the coil reactance, so the rating of the power transistor of the three-phase power converter 6 can be reduced.
(い)同期機動作は、回転子4が10rpm〜20rp
mに達してから行われるので、回転子4の磁極部41.
42の位置検出は容易であり、位置検出不能に陥らない
。(b) In the synchronous machine operation, the rotor 4 rotates between 10 rpm and 20 rpm.
Since it is performed after reaching the magnetic pole part 41.m of the rotor 4.
42 is easy to detect, and the position cannot be detected.
(う)電機子巻線3による回転磁界の磁界分布の周期は
、回転子磁極ピッチに等しく、誘導トルクは回転子磁気
回路に回転磁界磁束が貫通し、該磁束に磁極間のアルミ
導体電流が鎖交することで生じる。(c) The period of the magnetic field distribution of the rotating magnetic field by the armature winding 3 is equal to the rotor magnetic pole pitch, and the induced torque is caused by the rotating magnetic field magnetic flux penetrating the rotor magnetic circuit, and the aluminum conductor current between the magnetic poles being added to the magnetic flux. It is caused by interlinkage.
ここで、凹溝411が無い場合は、回転子4の磁気回路
は長く、貫通する磁束も少ない。しかし、凹溝411が
形成されアルミが充填されているのて、磁極面41a〜
41b〜41cと抜ける短ループの磁気回路磁束とアル
ミ導体電流の磁束ができるので、短ループとなった分、
磁束も増加し、誘導トルクが増加する。Here, if there is no groove 411, the magnetic circuit of the rotor 4 is long and there is little magnetic flux passing through it. However, since the groove 411 is formed and filled with aluminum, the magnetic pole faces 41a~
A short loop of magnetic circuit magnetic flux passing through 41b to 41c and a magnetic flux of the aluminum conductor current are created, so the short loop is created.
The magnetic flux also increases and the induced torque increases.
(え)車載エンジン1によりエンジン出力軸11を回転
し、回転子5が回転するので、三相コイル32から電力
が得られる。尚、発電電力の調整は、回転子用励磁巻線
5の巻線を流れる電流を電圧調整器(レギュレータ)で
調整することにより制御できる。(e) Since the engine output shaft 11 is rotated by the on-vehicle engine 1 and the rotor 5 is rotated, electric power is obtained from the three-phase coil 32. The generated power can be controlled by adjusting the current flowing through the rotor excitation winding 5 using a voltage regulator.
