Kodi brushless motor ndi chiyani ndipo imagwira ntchito bwanji?

Kodi brushless motor ndi chiyani ndipo imagwira ntchito bwanji?Tiyankha mafunso amenewa m’nkhani ino.

M'zaka za zida zamakono zamakono ndi zipangizo zamakono, n'zosadabwitsa kuti ma motors opanda brush akukhala ofala kwambiri muzinthu zomwe timagula.Ngakhale injini ya brushless idapangidwa chapakati pa zaka za zana la 19, sinali yogulitsa mpaka 1962.

Brushless motor, chifukwa chakuchita bwino kwambiri, kutumiza kwa torque yosalala, kulimba kwambiri komanso kuthamanga kwambiri, ikusintha pang'onopang'ono chojambuliracho.Ntchito zawo, m'mbuyomu, zakhala zochepa kwambiri ndi ndalama zowonjezera za owongolera magalimoto ovuta, omwe amafunikira kuyendetsa galimotoyo.

Ntchito zamkati mwa injini ziwirizi ndizofanana.Koyilo ya injiniyo ikapatsidwa mphamvu, imapanga mphamvu ya maginito kwakanthawi yomwe imathamangitsa kapena kukopa maginito okhazikika.

Zotsatira zake zimasinthidwa kukhala kuzungulira kwa shaft kuti injiniyo igwire ntchito.Pamene shaft ikuzungulira, panopa imayendetsedwa kumagulu osiyanasiyana, kotero kuti maginito a maginito amakopeka ndi kuthamangitsidwa, kulola kuti rotor ikhale yozungulira mosalekeza.

Galimoto yopanda maburashi ndiyothandiza kwambiri kuposa injini yojambulira pakusintha mphamvu yamagetsi kukhala mphamvu yamakina.Amasowa ma commutator, omwe amachepetsa kukonza ndi zovuta, komanso amachepetsa kusokoneza kwamagetsi.

Amatha kupanga torque yayikulu, kuyankha mwachangu, ndipo amatha kuwongolera chip imodzi (motor control unit).

Amagwiranso ntchito pa liwiro losiyanasiyana, kulola kuwongolera koyenda bwino komanso torque pakupuma.

Galimoto yopanda maburashi ndi mota yojambulira waya ndizosiyana kwambiri pamapangidwe.

Burashi imagwiritsidwa ntchito pamototo wa burashi kuti isamutsire pano kupita ku ma windings kudzera pa ma commutator.

Komabe, mota yopanda maburashi sifunika commutator.Mphamvu ya maginito ya injiniyo imasinthidwa ndi amplifier yoyambitsidwa ndi chipangizo chobwerera kumbuyo.Chitsanzo ndi optical encoder kuyeza mayendedwe abwino chifukwa sadalira gawo la kayendedwe.

Mapiritsi a injini yojambulira amakhala pa rotor ndipo ali pa brushless motor stator.Kufunika kwa burashi kumatha kuthetsedwa mwa kupeza koyilo pamalo osasunthika a stator kapena mota.

Mwachidule, kusiyana kwakukulu pakati pa brushless motor ndi brushed motor ndi kuti palibe maginito osasunthika ndi mawaya ozungulira (ophwanyidwa), ndipo ma brushless motors ali ndi mawaya okhazikika ndi maginito ozungulira.Ubwino waukulu ndi brushless mota popanda kukangana, motero kuchepetsa kutentha ndi kuwongolera bwino lonse.
