Kuj tseem muaj cov npluav DC motors hauv cov motors loj. Txais tos rau lag luam wholesale lub cev muaj zog loj
Brushless DC lub cev muaj zog siv cov khoom siv sib pauv hloov pauv kom paub txog kev xa khoom hluav taws xob, uas yog, cov khoom siv hluav taws xob hloov pauv tau raug siv los hloov cov kev sib txuas lus rau tus neeg siv khoom siv thiab tus txhuam. Nws muaj qhov zoo ntawm kev ntseeg siab, tsis muaj cuam tshuam hluav taws xob, thiab lub suab qis tshuab. Nws yog dav siv hauv high-end audio jacks, cov kab kaw duab, cov twj siv hluav taws xob thiab cov cuab yeej siv hauv chaw ua haujlwm.
Brushless DC lub cev muaj zog yog lub zuaj ruaj khov ruaj ruaj rotor, ntau tus ncej winding stator, thiab muaj lub ntsej muag sensor. Txoj hauj lwm paub txiav txim siab ntawm stator winding tam sim no nyob rau hauv ib qho kev txiav txim raws li qhov kev hloov ntawm lub rotor txoj hauj lwm (uas yog, kuaj xyuas qhov chaw ntawm lub rotor ncej txheeb ze rau stator winding, thiab tsim kom muaj txoj hauj lwm hnov lub teeb liab ntawm qee txoj haujlwm, uas yog ua los ntawm cov teeb liab hloov hluav taws xob Circuit Court Txhawm rau tswj lub hwj huam hloov Circuit Court, hloov lub xov tooj cua tam sim no raws li qee qhov kev sib raug zoo. Qhov ua hauj lwm voltage ntawm stator winding yog muab los ntawm hluav taws xob hloov Circuit Court tswj los ntawm txoj hauj lwm sensor tso tawm.
Muaj peb yam ntawm txoj hauj lwm sensors: sib nqus rhiab, photoelectric thiab electromagnetic. Brushless DC motors siv sib nqus-rhiab qhov chaw cov khoom siv, uas nws cov khoom sib nqus sib xyaw (xws li Hall cov khoom, magneto-rhiab diodes, magneto-rhiab ncej tubes, magneto-rhiab resistors lossis daim ntawv thov tshwj xeeb kev sib xyaw, thiab lwm yam) tau teeb tsa rau ntawm tus stator los ua ke. Txhawm rau txhawm rau hloov qhov kev hloov pauv ntawm cov hlau nplaum tom qab tsim thaum lub hlau nplaum tas mus li thiab lub rotor tig.
Lub brushless DC tsav nrog photoelectric txoj hauj lwm sensor yog nruab nrog photoelectric sensor nyob rau hauv ib txoj hauj lwm ntawm lub stator los ua ke, daim ntaub thaiv yog teeb tsa rau lub rotor, thiab cov khoom siv hluav taws xob yog lub teeb emitting diode lossis lub teeb me me. Thaum lub rotor tig, qhov sib txuas ntawm cov duab hluav taws xob nyob ntawm tus stator yuav ua rau muaj cov teeb liab mem tes sib cuam tshuam nyob rau qee qhov zaus vim muaj cov txiaj ntsig ntawm lub teeb thaiv.
Brushless DC motors nrog electromagnetic position sensors yog nruab nrog electromagnetic sensor Cheebtsam (xws li txuas hloov pauv, sib thooj hloov mus, LC resonance circuits, thiab lwm yam) ntawm cov hluav taws xob sib dhos. Thaum txoj hauj lwm ntawm lub cim ruaj khov rotor hloov pauv, cov hluav taws xob muaj zog yuav ua rau lub ntsuas hluav taws xob ua rau lub tshuab hluav taws xob muaj ntau lub teeb liab hloov pauv (nws qhov txawv txav nrog lub rotor txoj hauj lwm).
