Brushless DC motors muaj lub cev muaj zog thiab tus tsav tsheb, thiab yog cov khoom siv mechatronic. Lub stator windings feem ntau tau teeb tsa hauv peb -theem symmetrical hnub qub kev sib txuas, zoo ib yam li peb -theem asynchronous lub cev muaj zog. Cov hlau nplaum ruaj khov txuas nrog rau lub rotor, thiab ib txoj hauj lwm sensor tau nruab rau hauv lub cev kom pom lub rotor polarity. Tus neeg tsav tsheb, tsim los ntawm cov khoom siv hluav taws xob hluav taws xob thiab kev sib txuas ua ke, ua haujlwm rau: tau txais kev pib, nres, thiab nres nres ntawm lub cev muaj zog los tswj cov kev ua no; tau txais txoj hauj lwm sensor teeb liab thiab rau pem hauv ntej / thim rov qab teeb liab los tswj kev hloov ntawm lub hwj chim transistors nyob rau hauv inverter choj, generating nruam torque; tau txais cov lus txib ceev thiab cov lus qhia ceev ceev los tswj thiab kho qhov ceev; thiab muab kev tiv thaiv thiab tso saib ua haujlwm, thiab lwm yam.
Vim tias brushless DC motors ua haujlwm ntawm tus kheej - tswj hwm, lawv tsis tas yuav muaj kev pib winding ntawm lub rotor ntxiv xws li synchronous motors nyob rau hauv hnyav load pib nrog zaus converters, thiab lawv tsis muaj oscillations los yog poob ntawm synchronism thaum lub sij hawm tam sim ntawd load hloov. Cov hlau nplaum ruaj khov ntawm me me - mus rau - nruab nrab muaj peev xwm brushless DC motors feem ntau siv siab - zog- khoom tsis tshua muaj - ntiaj teb neodymium hlau boron (Nd-Fe-B) cov ntaub ntawv. Yog li ntawd, qhov luaj li cas ntawm qhov tsis tshua muaj -lub ntiaj teb cov hlau nplaum txhuam tsis muaj lub cev muaj zog raug txo los ntawm ib lub thav duab loj piv rau peb -theem asynchronous lub cev muaj zog ntawm tib lub peev xwm. Kev tshawb fawb txog kev hloov pauv ceev ceev ntawm asynchronous motors nyob rau peb caug xyoo dhau los tau tsom mus rau kev nrhiav txoj hauv kev los tswj lub zog ntawm asynchronous motors. Tsis tshua muaj- lub ntiaj teb cov hlau nplaum ruaj khov brushless DC lub cev muaj zog yuav ua kom pom qhov zoo hauv kev tswj kev ceev vim lawv qhov dav dav, me me, kev ua haujlwm siab, thiab me me ruaj khov- xeev ceev yuam kev. Vim hais tias brushless DC motors muaj cov yam ntxwv ntawm brushed DC motors thiab kuj yog zaus - hloov khoom siv, lawv kuj hu ua DC inverters, thoob ntiaj teb hu ua BLDC. Kev ua haujlwm tau zoo, qis-ceev torque, thiab ceev qhov tseeb ntawm brushless DC motors yog superior rau lwm yam kev tswj technology siv nyob rau hauv zaus converters, ua rau lawv tsim nyog ntawm kev lag luam mloog. Cov khoom lag luam siab tshaj 55kW twb tau tsim, nrog rau kev tsim tawm mus txog 400kW, hais txog kev lag luam kev xav tau rau kev txuag hluav taws xob thiab kev ua haujlwm siab - tsav.
