Cov hlau nplaum ruaj khov synchronous motors muaj xws li stator, rotor, thiab cov hlau nplaum ruaj khov. Lub stator windings tsim kom muaj qhov sib nqus sib nqus, thiab lub rotor cov hlau nplaum ruaj khov magnetic teb rotates synchronously nrog nws. Nws txoj haujlwm ua haujlwm yog ua raws li electromagnetic induction thiab Lorentz quab yuam, ua tiav kev tswj ceev los ntawm kev tswj xyuas meej ntawm cov stator tam sim no. Piv rau cov tsoos asynchronous motors, nws tshem tawm cov qauv rotor coil, txo qhov kev poob siab.
Kev faib tawm los ntawm Excitation Current Supply Method
Cov hlau nplaum tas mus li synchronous motors siv cov hlau nplaum tas mus li los tsim kom muaj kev sib nqus magnetic. Lub stator generates ib rotating magnetic teb, thiab lub rotor yog ua los ntawm cov hlau nplaum ruaj khov. Synchronous motors xav tau DC magnetic teb kom ua tiav lub zog hloov dua siab tshiab; DC tam sim no uas tsim qhov chaw sib nqus no hu ua lub cev muaj zog excitation tam sim no.
Separately Excited Motors: Cov motors uas tau txais lawv cov excitation tam sim no los ntawm lwm qhov chaw fais fab.
Tus kheej-Cov Tsav Tsheb Txaus Siab: Cov motors uas tau txais lawv cov excitation tam sim no los ntawm lub cev muaj zog nws tus kheej.
Kev faib tawm los ntawm Kev Siv Hluav Taws Xob Zaus
Cov hlau nplaum tas mus li brushless lub cev muaj xws li ob hom: cov hlau nplaum ruaj khov brushless DC motors thiab cov hlau nplaum tas mus li brushless AC motors. Ob leeg yuav tsum muaj zaus converters rau kev ua haujlwm. Lub qub tsuas xav tau ib lub xwmfab -wave inverter rau lub hwj chim mov, thaum lub tom kawg yuav tsum tau ib tug sinusoidal -wave inverter.
Kev faib tawm los ntawm Air Gap Magnetic Field Distribution:
Sinusoidal Permanent Magnet Synchronous Tsav: Cov ncej hlau nplaum siv cov khoom siv hlau nplaum ruaj khov. Thaum peb lub -theem sinusoidal tam sim no yog input, huab cua sib nqus magnetic teb raug faib raws li txoj cai sinusoidal. Qhov no tsuas yog hu ua cov hlau nplaum ruaj khov synchronous lub cev muaj zog.
Trapezoidal Permanent Magnet Synchronous Tsav: Cov ncej hlau nplaum tseem ua los ntawm cov khoom siv hlau nplaum ruaj khov, tab sis thaum lub xwmfab yoj tam sim no nkag mus, huab cua sib nqus sib nqus ua rau muaj kev faib tawm yoj trapezoidal. Nws qhov kev ua tau zoo yog ze rau ntawm DC lub cev muaj zog. Tus kheej -tswj kuj sib txawv zaus synchronous motors tsim siv lub trapezoidal yoj mus tas li hlau nplaum synchronous motors kuj hu ua brushless DC motors.
