A rotating magnetic teb yog qhov tshwm sim magnetic teb uas tsim los ntawm cov txheej txheem ntawm coils symmetrically muab tso rau thiab muab nrog polyphase tam sim no.
Yuav ua li cas tig magnetic teb tsim?
Lub rotating magnetic teb yog tsim los ntawm peb-theem tam sim no ntawm stator nyob rau hauv qhov tseeb peb-theem induction motor Nws tuaj yeem hloov tau los ntawm cov hlau nplaum ruaj khov hauv cov hlau nplaum ruaj khov synchronous lub cev muaj zog. Peb-theem windings ntawm lub puab stator yog spaced 120 ° hluav taws xob degrees sib nrug.
Yuav ua li cas tig magnetic teb piav qhia nrog phasor daim duab?
Thaum lub 3-theem winding yog energized los ntawm 3-theem mov, lub rotating magnetic teb yog tsim. Daim teb no yog xws li tias nws cov ncej tsis nyob hauv qhov chaw ruaj khov ntawm stator tab sis mus hloov lawv txoj haujlwm nyob ib puag ncig statorVim li no, thiaj li hu ua rotating field.
Yuav ua li cas tig magnetic teb nws cuam tshuam lub tshuab li cas?
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm AC cov tshuab yog tsim los ntawm kev sib hloov magnetic teb, uas ua rau lub rotor tig ntawm qhov nrawm uas nyob ntawm qhov ceev ntawm kev sib hloov ntawm cov hlau nplaum.
Yuav ua li cas tig teb qhov system?
Muaj ob hom kev hloov pauv siv ib qho yog tig hom armature thiab lwm qhov yog tig hom teb. Nyob rau hauv rotating armature alternator, lub teb yog nyob ruaj ruaj thiab armature yog rotating whereas nyob rau hauv rotating teb alternator armature yog nyob ruaj ruaj thiab teb yog rotating.
