Tham txog lub nraub qaum electromotive quab yuam ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog

1. Yuav ua li cas rov qab electromotive quab yuam?

Rov qab electromotive quab yuam tseem hu ua induced electromotive force. Txoj Cai: tus neeg xyuas pib txiav cov kab sib nqus ntawm lub zog.

Lub rotor ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog yog cov hlau nplaum ruaj khov, thiab lub stator yog qhov txhab nrog coils. Thaum lub rotor rotates, lub magnetic teb generated los ntawm cov hlau nplaum mus tas li yog txiav los ntawm cov coils ntawm stator, tsim ib tug rov qab electromotive quab yuam ntawm lub kauj (nyob rau hauv lub opposite kev taw qhia rau lub davhlau ya nyob twg voltage U).

2. Kev sib raug zoo ntawm rov qab electromotive quab yuam thiab qhov hluav taws xob davhlau ya nyob twg

3. Lub ntsiab lus ntawm lub cev rov qab electromotive quab yuam

Rov qab EMF: tsim lub zog muaj txiaj ntsig thiab sib cuam tshuam nrog kev poob cua sov (xws li lub peev xwm hloov pauv ntawm cov khoom siv hluav taws xob).

4. Qhov loj ntawm rov qab electromotive quab yuam

Saum toj no:

(1) Lub nraub qaum EMF yog sib npaug ntawm qhov hloov pauv ntawm cov hlau nplaum sib nqus. Qhov siab dua qhov ceev, qhov ntau dua qhov hloov pauv thiab ntau dua EMF rov qab.

(2) Lub flux nws tus kheej yog sib npaug rau tus naj npawb ntawm lem multiplied los ntawm flux ib tig. Yog li ntawd, qhov ntau dua ntawm cov lem, qhov ntau dua qhov flux thiab ntau dua EMF rov qab.

(3) Tus naj npawb ntawm cov lem muaj feem xyuam rau lub tswv yim winding, lub hnub qub-delta kev twb kev txuas, tus naj npawb ntawm cov lem ntawm ib lub qhov, tus naj npawb ntawm cov theem, tus naj npawb ntawm cov hniav, tus naj npawb ntawm cov ceg sib txuas, thiab cov tswv yim puv-pitch lossis luv-pitch scheme;

(4) Ib zaug tig flux yog sib npaug rau lub zog magnetomotive faib los ntawm kev sib nqus tsis kam. Yog li ntawd, qhov loj dua lub zog magnetomotive, qhov me me ntawm qhov sib nqus tsis kam nyob rau hauv cov kev taw qhia ntawm cov flux thiab qhov loj dua lub nraub qaum electromotive quab yuam.

(5) Sib nqus tsis kam yog cuam tshuam nrog huab cua sib txawv thiab kev sib koom ua ke ntawm tus ncej. Qhov loj dua qhov sib txawv ntawm huab cua, qhov sib nqus ntawm qhov sib nqus ntau dua thiab qhov me me ntawm lub nraub qaum electromotive quab yuam. Kev sib koom ua ke ntawm ncej-slot yog qhov nyuaj thiab xav tau kev tshuaj xyuas tshwj xeeb;

(6) Lub zog magnetomotive muaj feem xyuam rau cov hlau nplaum seem ntawm cov hlau nplaum thiab thaj chaw zoo ntawm cov hlau nplaum. Qhov loj dua qhov seem hlau nplaum, qhov siab dua qhov rov qab electromotive quab yuam. Qhov chaw zoo yog cuam tshuam nrog cov kev taw qhia magnetization, qhov loj thiab qhov chaw ntawm cov hlau nplaum, uas yuav tsum muaj kev tsom xam tshwj xeeb;

(7) Remanence kuj muaj feem xyuam rau qhov kub thiab txias. Qhov siab dua qhov kub, qhov me me tom qab EMF.

Hauv cov ntsiab lus, cov yam ntxwv cuam tshuam rov qab EMF suav nrog kev sib hloov ceev, tus lej ntawm qhov hloov pauv, tus lej ntawm cov theem, tus lej ntawm cov ceg sib txuas, lub suab thiab lub suab luv luv, lub cev muaj zog sib nqus hluav taws xob, qhov sib txawv ntawm huab cua ntev, ncej-qhov sib txuam, sib nqus hlau remanence, Sib nqus hlau tso thiab qhov loj me, sib nqus hlau hlau magnetization kev taw qhia, thiab kub.
