Dab tsi yog brushless lub cev muaj zog--ua haujlwm txoj cai

Brushless DC lub cev muaj zog (BLDC lub cev muaj zog lossis BL lub cev muaj zog) siv cov khoom siv hluav taws xob hloov pauv kom paub txog hluav taws xob commutator, uas yog, cov khoom siv hluav taws xob hloov pauv hloov cov kev sib cuag ib txwm muaj thiab txhuam. thiab lwm yam.Nws yog dav siv nyob rau hauv high-grade kaw lub rooj, video recorder, electronics instruments thiab chaw ua hauj lwm automation khoom.

Brushless DC lub cev muaj zog yog tsim los ntawm cov hlau nplaum ruaj khov rotor, ntau tus ncej winding stator thiab txoj hauj lwm sensor.Position sensing raws li qhov kev hloov ntawm rotor txoj hauj lwm, raws li ib theem zuj zus ntawm stator winding tam sim no converter (xws li nrhiav tau lub rotor magnetic ncej txheeb ze rau txoj hauj lwm ntawm stator winding. , thiab hauv kev txiav txim siab qhov chaw ntawm qhov chaw sensor teeb liab, lub teeb liab hloov hluav taws xob los tswj lub zog hloov hluav taws xob, tom qab ua tiav raws li qee qhov kev sib raug zoo ntawm winding tam sim no hloov). los ntawm cov zis ntawm qhov chaw sensor.

Muaj peb hom ntawm txoj hauj lwm sensors: magnetic-sensitive, photoelectric thiab electromagnetic.

Brushless DC lub cev muaj zog nrog sib nqus-rhiab qhov chaw sensor, nws qhov sib nqus-rhiab sensor qhov chaw (xws li cov khoom siv, sib nqus-sensitive diode, sib nqus-rhiab ncej raj, sib nqus-rhiab resistor lossis tshwj xeeb kev sib xyaw ua ke, thiab lwm yam) tau nruab rau ntawm stator. sib dhos los xyuas qhov sib nqus teb hloov pauv los ntawm cov hlau nplaum ruaj khov thiab rotor kev sib hloov.

Lub brushless DC lub cev muaj zog nrog photoelectric txoj hauj lwm sensor yog nruab nrog photoelectric sensor ntawm ib qho chaw ntawm lub stator los ua ke, ib qho screen yog ntsia rau ntawm lub rotor, thiab lub teeb qhov chaw yog coj los yog me me qhov muag teev.Thaum lub rotor yog rotating, vim lub luag hauj lwm. ntawm lub shutter, cov photosensitive Cheebtsam ntawm lub stator yuav intermittently tsim mem tes signals ntawm ib tug tej zaus.

Siv electromagnetic txoj hauj lwm sensor brushless dc lub cev muaj zog, yog nyob rau hauv lub electromagnetic sensors yog ntsia rau ntawm lub stator tivthaiv qhov chaw (xws li lub coupling transformer, ze rau hloov, LC resonance Circuit Court, thiab lwm yam), thaum lub sij hawm mus tas li hlau nplaum rotor txoj hauj lwm hloov, electromagnetic nyhuv yuav ua kom lub tshuab hluav taws xob ua hluav taws xob tsim hluav taws xob hloov hluav taws xob ntau zaus (qhov amplitude hloov nrog rotor txoj hauj lwm)

JIUYUAN muaj ntau tshaj 20 xyoo kev paub txogme brushless dc lub cev muaj zog,sab nrauv rotor brushless dc lub cev muaj zog,puab rotor brushless dc lub cev muaj zog, brushless dc lub cev muaj zog nrog xws li lossis tsav thiab lwm yam ..
