Kev ua hauj lwm sib nqus flux ntawm DC brushless lub cev muaj zog yuav tsum yog raws li cov huab cua sib nqus sib nqus flux tsim los ntawm qhov nruab nrab sib nqus flux ntom ntom ntawm cov hlau nplaum hauv cov hlau nplaum ntawm lub kauj. Qhov siab tshaj plaws ntawm qhov sib nqus flux ceev ntawm txhua tus ncej ntawm cov hlau nplaum yuav tsum yog qhov remanence ntawm cov hlau nplaum, thiab qhov sib nqus flux ceev nyob rau hauv ntau qhov chaw ntawm cov hlau nplaum yuav tsis tshaj qhov siab tshaj plaws sib nqus flux ntom ntawm cov hlau nplaum.
(1) Kev cuam tshuam ntawm cov neeg kho tshuab ncej arc coefficient ntawm cov hlau nplaum. Yog hais tias tus neeg kho tshuab nrog lub kaum sab xis ntawm qhov chaw-mounted hlau nplaum yog me dua tus ncej ntawm cov hlau nplaum, ces cov hlau nplaum ntawm cov hlau nplaum yuav tsum raug cuam tshuam thiab txo. Qhov coefficient no yog qhov sib piv ntawm qhov dav ntawm qhov sib nqus flux ncej arc rau ncej ncej ntawm cov hlau nplaum, uas yog hu ua Mechanical pole arc coefficient.
(2) Kev cuam tshuam ntawm magnetic ncej arc coefficient ntawm cov hlau nplaum hlau. Vim tias qhov sib nqus flux ntom ntom faib waveform ntawm cov hlau nplaum tsis tas yuav yog lub voj voog square, nws yuav yog sine yoj, eeb nthwv dej, yoj trapezoidal, thiab lwm yam, yog li cov coefficient ntawm qhov nruab nrab magnetic flux ntom yuav tsum sib txawv. Vim li no, tus coefficient yuav tsum tau siv. Multiplied los ntawm qhov siab tshaj plaws sib nqus flux ceev ntawm cov hlau nplaum, nws sawv cev rau qhov tseeb nruab nrab magnetic flux ceev ntawm cov hlau nplaum. Qhov coefficient no tuaj yeem hu ua magnetic ncej arc coefficient ntawm cov hlau nplaum.
(3) Lub thickness ntawm cov hlau nplaum yog qhov ntev ntawm cov hlau nplaum hlau. Cov huab cua sib txawv ntawm lub cev muaj zog yuav tag nrho txo qhov sib nqus flux ceev ntawm cov hlau nplaum rau hauv cov pa sib nqus sib nqus flux ceev ntawm lub cev muaj zog, uas ua rau cov cua sib txawv qis dua qhov siab tshaj plaws sib nqus flux ceev ntawm cov hlau nplaum. Qhov nruab nrab magnetic flux ceev.
(4) Qhov nruab nrab magnetic flux ceev ntawm huab cua kis yog cov khoom ntawm ntau yam luv nqi yam khoo los ntawm lub siab tshaj plaws magnetic flux ceev ntawm lub magnetic hlau. Raws li kev suav hauv paus thiab txoj kev hloov pauv cov hlau nplaum hlau nplaum sib nqus ntawm DC brushless lub cev muaj zog rau hauv qhov nruab nrab sib nqus flux ceev ntawm lub cev muaj zog cua sib txawv. Los ntawm lwm qhov kev xav, txij li qhov sib txawv ntawm huab cua yog qhov nruab nrab, nws yuav tsum tau xav tias qhov kev faib tawm ntawm huab cua sib txawv hauv cov huab cua sib txawv ntawm DC brushless lub cev muaj zog tsis sib xws, yog li cov huab cua sib txawv ntawm lub cev muaj zog thiab sib nqus. flux ntawm lub cev muaj zog rotor Tus naj npawb ntawm cov ncej tsis cuam tshuam. Yog hais tias lub sib nqus ntawm lub magnetic steel yog cov tib yam thiab lub waveform ntawm lub magnetic flux ceev tis yog tib yam, ces tus naj npawb ntawm cov magnetic steel rau qhov ib ncig ntawm cov huab cua kis muaj tsis muaj dab tsi ua nrog rau qhov nruab nrab sib nqus flux ceev thiab cua kis magnetic flux generated. Lub tswv yim tsis sib xws ntawm huab cua sib txawv yog siv los txiav txim siab txog cov txiaj ntsig ntawm lub cev muaj zog, uas pab txhawb kev tsim thiab suav cov motors tsis muaj brushless DC yav tom ntej.
