Choyatsira Mafani cha PWM 92mm 12V Chopanda Brush 12/24V DC Choyatsira Mpweya Chosasuntha 92*60

Mu ma mota a DC opanda brushless, makina amagetsi a servo amalowa m'malo mwa makina olumikizirana ndi ma commutator. Sensa yamagetsi imazindikira ngodya ya rotor ndikuwongolera ma switch a semiconductor monga ma transistors omwe amasinthasintha mphamvu kudzera m'ma windings, mwina kubweza njira ya mphamvu kapena, m'ma mota ena kuizimitsa, pa ngodya yoyenera kotero ma electromagnet amapanga torque mbali imodzi. Kuchotsa kulumikizana kotsetsereka kumalola ma mota opanda brush kukhala ndi kukangana kochepa komanso moyo wautali; moyo wawo wogwirira ntchito umachepetsedwa ndi moyo wa ma bearing awo.

Ma mota a DC opangidwa ndi burashi amakhala ndi mphamvu yayikulu kwambiri akakhazikika, zomwe zimachepa pang'onopang'ono pamene liwiro likukwera. Zofooka zina za ma mota opangidwa ndi burashi zimatha kuthetsedwa ndi ma mota opanda burashi; zimaphatikizapo kugwira ntchito bwino kwambiri komanso kufooka kochepa chifukwa cha kuwonongeka kwa makina. Ubwino uwu umabwera chifukwa cha mtengo wa zida zamagetsi zowongolera zomwe sizingakhale zolimba kwambiri, zovuta kwambiri, komanso zokwera mtengo kwambiri.

Mota yamagetsi yopanda burashi imakhala ndi maginito okhazikika omwe amazungulira mozungulira armature yokhazikika, zomwe zimachotsa mavuto okhudzana ndi kulumikiza magetsi ku armature yoyenda. Chowongolera zamagetsi chimalowa m'malo mwa commutator assembly ya mota ya DC yolumikizidwa, yomwe nthawi zonse imasinthira gawolo ku ma windings kuti mota ipitirize kutembenuka. Chowongolera chimagwira ntchito yogawa mphamvu yofanana ndi nthawi pogwiritsa ntchito solid-state circuit m'malo mwa commutator system.
