Kuyambitsa kwa mota ya DC yopanda brushless mu zida zamagetsi

Chifukwa cha kusintha kwa ukadaulo watsopano wa mabatire ndi zamagetsi, mtengo wa kapangidwe ndi kupanga mota ya DC yopanda maburashi wachepetsedwa kwambiri, ndipo zida zosavuta zochapira zomwe zimafuna mota ya DC yopanda maburashi zatchuka kwambiri ndipo zagwiritsidwa ntchito kwambiri. Imagwiritsidwa ntchito kwambiri m'mafakitale opanga, omanga ndi kukonza mafakitale, makamaka chifukwa cha chitukuko cha zachuma, kufunikira kwa nyumba kukukulirakulira, ndipo kuchuluka kwa pachaka kukukwera kwambiri kuposa mafakitale ena.

2, injini yamagetsi yogwiritsidwa ntchito bwino yomwe ingabwezeretsedwenso

2.1 Mota ya DC yopukutidwa

Kapangidwe ka injini ya DC yopanda burashi wamba kamaphatikizapo rotor (shaft, iron core, winding, commutator, bearing), stator (casing, magnet, end cap, etc.), carbon burashi assembly, carbon burashi arm ndi zina.

Mfundo yogwirira ntchito: Stator ya mota ya DC yopukutidwa imayikidwa ndi pole yayikulu yokhazikika (maginito) ndi burashi, ndipo rotor imayikidwa ndi armature winding ndi commutator. Mphamvu yamagetsi ya DC power supply imalowa mu armature winding kudzera mu burashi ya kaboni ndi commutator, ndikupanga armature current. Mphamvu ya maginito yopangidwa ndi armature current imagwirizana ndi maginito akuluakulu kuti ipange electromagnetic torque, zomwe zimapangitsa mota kuzungulira ndikuyendetsa katundu.

Zoyipa: Chifukwa cha kukhalapo kwa burashi ya kaboni ndi commutator, kudalirika kwa injini ya burashi ndi kochepa, kulephera, kusakhazikika kwamakono, moyo waufupi, ndi mphamvu ya commutator zimapangitsa kusokoneza kwa maginito.

2.2 Mota ya DC yopanda burashi

Kapangidwe ka injini ya DC yopanda burashi wamba kamaphatikizapo rotor ya injini (shaft, iron core, magnet, bearing), stator (casing, iron core, winding, sensor, end cover, etc.) ndi zigawo zowongolera.

Mfundo yogwirira ntchito: Mota ya DC yopanda brushless imakhala ndi thupi la injini ndi dalaivala, ndi chinthu chodziwika bwino cha mechatronics. Mfundo yogwirira ntchito ndi yofanana ndi ya mota ya brush, koma burashi yachikhalidwe ya commutator ndi carbon burashi imasinthidwa ndi sensor ya malo ndi mzere wowongolera, ndipo njira yamagetsi imasinthidwa ndi lamulo lowongolera lomwe limaperekedwa ndi chizindikiro chozindikira kuti ntchito yosinthira ichitike, kuti zitsimikizire kuti torque yamagetsi ndi chiwongolero cha mota zimayenda nthawi zonse ndikupangitsa mota kuzungulira.

Kusanthula kwa mota ya DC yopanda brushless mu zida zamagetsi

3. Ubwino ndi kuipa kwa kugwiritsa ntchito injini ya BLDC

3.1 Ubwino wa mota ya BLDC:

3.1.1 Kapangidwe kosavuta komanso khalidwe lodalirika:

Chotsani commutator, burashi ya kaboni, mkono wa burashi ndi zina, palibe kuwotcherera commutator, njira yomaliza.

3.1.2 Moyo wautali wa ntchito:

Kugwiritsa ntchito zida zamagetsi m'malo mwa kapangidwe ka commutator kachikhalidwe, kuchotsa mota chifukwa cha burashi ya kaboni ndi commutator commutator spark, kuwonongeka kwa makina ndi mavuto ena omwe amayamba chifukwa cha moyo waufupi, moyo wa mota umawonjezeka ndi zingapo.

3.1.3 Chete komanso kugwira ntchito bwino kwambiri:

Popanda burashi ya kaboni ndi kapangidwe ka commutator, pewani kung'anima kwa commutator ndi kukangana kwa makina pakati pa burashi ya kaboni ndi commutator, zomwe zimapangitsa phokoso, kutentha, kutayika kwa mphamvu ya injini, komanso kuchepetsa kugwira ntchito bwino kwa injini. Kugwiritsa ntchito bwino kwa injini ya DC yopanda brush mu 60~70%, ndipo kugwiritsa ntchito bwino kwa injini ya DC yopanda brush kumatha kufika 75~90%

3.1.4 Kulamulira ndi kulamulira liwiro lonse:

Zipangizo zamagetsi ndi masensa olondola amatha kuwongolera molondola liwiro lotulutsa, mphamvu ndi malo a injini, pozindikira kuti ndi yanzeru komanso yogwira ntchito zambiri.
