Description
B2D 外径側のロータ
B23,B25,B27 内径側のステータ磁極
B24,B26,B28 外径側のステータ磁極
B29,B2A a相の巻線
B2B,B2C b相の巻線
図34は、関連技術のブラシレスモータの断面図である。図34に示すブラシレスモータ150は、3相交流で動作する8極モータであり、ロータ11、永久磁石12、ステータ14を含んで構成されている。
=−Wu ×dφu /dθ×dθ/dt
=−Wu ×Eu ×S1 …(1)
同様に、
Vv =Wv ×Ev ×S1 …(2)
Vw =Ww ×Ew ×S1 …(3)
ここで、具体的な巻線と電圧の関係は次のようになる。U相の単位電圧Eu は、図34および図39に示されるU相巻線15の逆向きの1ターンに発生する電圧である。U相電圧Vu は、U相巻線15の逆向きに発生する電圧である。V相の単位電圧Ev は、V相巻線16の1ターンとV相巻線17の逆向きの1ターンとを直列に接続したときに両端に発生する電圧である。V相電圧Vv は、V相巻線16と逆向きのV相巻線17とを直列に接続したときの両端の電圧である。W相の単位電圧Ew は、図34および図39に示されるW相巻線18の1ターンに発生する電圧である。W相電圧Vw は、W相巻線18の逆向きに発生する電圧である。
Pu =Vu ×(−Iu )=Wu ×Eu ×S1×Iu …(4)
Pv =Vv ×Iv =Wv ×Ev ×S1×Iv …(5)
Pw =Vw ×Iw =Ww ×Ew ×S1×Iw …(6)
Pa =Pu +Pv +Pw =Vu ×Iu +Vv ×Iv +Vw ×Iw …(7)
となる。また、ブラシレスモータ150の出力トルクTa 、各相のトルクTu 、Tv 、Tw は、
Tu =Pu /S1=Wu ×Eu ×Iu …(8)
Tv =Pv /S1=Wv ×Ev ×Iv …(9)
Tw =Pw /S1=Ww ×Ew ×Iw …(10)
Ta =Tu +Tv +Tw
=Wu ×Eu ×Iu +Wv ×Ev ×Iv +Ww ×Ew ×Iw
=Wc ×(Eu ×Iu +Ev ×Iv +Ew ×Iw) …(11)
となる。なお、本実施形態のブラシレスモータ150の電圧、電流、トルクに関するベクトル図は、図264、図265、図266に示した従来のブラシレスモータのベクトル図と同じである。
En =Ew =dφw /dθ
また、各巻線の電圧V、パワーP、トルクTのベクトル算式は以下のようになる。
Vn =Wc ×En ×S1 …(13)
Pm =Vm ×Im =Wc ×(−Eu )×S1×(−Iu +Iv )
=Wc ×Eu ×S1×(−Iu +Iv ) …(14)
Pn =Vn ×In =Wc ×Ew ×S1×(−Iv +Iw )…(15)
Pb =Pm +Pn =Vu ×(−Iu +Iv )+Vw ×(−Iv +Iw )…(16)
Tm =Pm /S1=Wc ×(−Eu )×(−Iu +Iv )…(17)
Tn =Pn /S1=Wc ×Ew ×(−Iv +Iw ) …(18)
Tb =Tm +Tn =Wc ×((−Eu ×Im )+Ew ×In ) …(19)
=Wc ×(−Eu ×(−Iu +Iv )+Ew ×(−Iv +Iw ))
=Wc ×Eu ×Iu +Wc ×Iv ×(−Eu −Ew )+Wc ×Ew ×Iw
=Wc ×(Eu ×Iu +Ev ×Iv +Ew ×Iw ) …(20)
∵ Eu +Ev +Ew =0 …(21)
ここで、(11)式で示されたトルク式は3相で表現され、(19)式で示されたトルク式は2相で表現されている。これらのトルク式の表現方法は異なるが、(19)式を展開すると(20)式となり、これら両式は数学的に等価であることがわかる。特に、電圧Vu 、Vv 、Vw および電流Iu 、Iv 、Iw が平衡3相交流の場合は(11)式で示されるトルクTa の値は一定となる。このとき、(19)式で示されるトルクTb は、図42に示すように、Tm とTn との位相差であるKmn=90°となる正弦波の2乗関数の和として得られ、一定値となる。
漏れ磁束が発生じにくい配置構造となっている。もし漏れ磁束が増加する場合には,導体内に渦電流が発生し,磁束の増加を妨げる効果があるためである。図54に示す各相のステータ磁極の間へは各巻線が同様に配置構造となっていて、他相のステータ磁極間の漏れ磁束を極力低減させる構造となっている。図54及び図55に示すような構造のモータとすることにより、大きなピークトルクが得られる構造となっている。
Ψq=Lq・iq ・・・(2)
T =Pn(Ld−Lq )iq ・id ・・・(3)
=Pn(Ψd・iq−Ψq・id ) ・・・(4)
vd=Ld・d(id)/dt−ω・Lq・iq+id・R ・・・(5)
vq=Lq・d(iq)/dt+ω・Ld・id+iq・R ・・・(6)
ここで,Pnは極対数,Rは巻線抵抗である。
