1. Musimboti musiyano: bhurashi mota inotora mechanical commutation, magnetic pole haifambi, cfuel inotenderera. Kana mota ichishanda, iyo cfuel uye commutator inotenderera, iyo magineti nekabhoni brashi haitenderere, uye shanduko yekuchinjika ye cfuel yazvino kutungamira inopedzwa nemufambi uye bhurashi rinotenderera nemota. Brushless mota inotora zvemagetsi commutation, cfuel haifambi uye magineti pole inotenderera.
2. Kusiyana kwekumhanya kwekugadzirisa maitiro: Kutaura zvazviri, zvose zvigadziridzo zvinotungamirirwa nemagetsi ekugadzirisa, chete nokuti brushless DC inoshandisa electronic commutation, digital control inodiwa. Brushless DC inofambiswa nekabhoni brashi, uye inogona kudzorwa neyechinyakare analog maseketi akadai sesilicon inodzorwa, iri nyore.
Kusiyana mukuita:
▶ 1. Iyo brashi mota ine chimiro chakareruka, nguva yakareba yekuvandudza uye tekinoroji yakakura.
Pakangozvarwa mota muzana ramakore regumi nepfumbamwe, mota inoshanda yakagadzirwa yaive brushless fomu, kureva AC squirrel-cage asynchronous mota, yakashandiswa zvakanyanya kubva pachizvarwa che AC. Zvisinei, kune zvakawanda zvisingagoneki kukanganisa mu asynchronous motor, kuitira kuti kukura kwekombiyuta yemotokari kunonoke.
▶ 2. DC brashi mota ine kukurumidza kupindura kumhanya uye hombe yekutanga torque:
DC bhurashi mota ine kukurumidza kutanga mhinduro, hombe yekutanga torque, yakatsetseka kumhanya shanduko, uye haigone kunzwa kudedera kubva ku zero kusvika kumhanyisa kumhanya. Inogona kutyaira mutoro mukuru paunotanga. Brushless mota ine hombe yekutanga kuramba (inductance), saka ine diki simba chinhu, diki yekutanga torque, inonyengerera kana ichitanga, ichiperekedzwa nekuzunguza kwakasimba, kudiki kutyaira kana uchitanga.
▶ 3. DC brashi mota inomhanya zvakanaka ine kutanga kwakanaka uye braking maitiro:
Mabhurashi mota anodzorwa nevoltage, saka tanga uye bhureki zvakanaka uye mhanya zvakanaka nekumhanya nguva dzose. Brushless mota dzinowanzodzorwa nedhijitari frequency kutendeuka. Kutanga AC inoshandurwa kuita DC, kozoita DC kuita AC. Kumhanya kunodzorwa ne frequency shanduko. Naizvozvo, mabhurashi motors anomhanya zvisina kuenzana kana achitanga uye mabhureki, aine vibration yakakura, uye chete kana kumhanya kwagara kuripo ndiko kunomhanya zvakanaka.
▶ 4. Kudzora kwakanyanya kweDC brush mota:
DC bhurashi mota inowanzo shandiswa pamwe chete negiya bhokisi uye decoder, izvo zvinoita kuti iyo mota inobuda simba ive yakakura uye kutonga kurongeka kwakakwira. Kurongeka kwekutonga kunogona kusvika 0.01 mm, uye inogona kumira kufambisa zvikamu chero kupi kwaunoda. Ese maturusi emuchina chaiwo anoshandisa DC mota kudzora kurongeka.
▶ 5. DC brashi mota ine mutengo wakaderera uye nyore kugadzirisa.
Nekuda kwechimiro chayo chiri nyore, mutengo wakaderera wekugadzira, vagadziri vazhinji uye tekinoroji yakakura, DC brashi mota inoshandiswa zvakanyanya uye isingadhure. Brushless mota tekinoroji haina kukura, mutengo wakakwira uye huwandu hwekushandisa hushoma. Inofanirwa kunyanya kushandiswa mumidziyo yekumhanyisa nguva dzose, senge variable frequency air conditioning, firiji, etc. Brushless motor damage inogona kungotsiviwa.
▶ 6. Kusashandisa bhurasho, kupindira kwakaderera:
Iyo brushless mota inobvisa mabhurashi uye shanduko yakananga ndeye kusavapo kwemagetsi emagetsi anogadzirwa kana brashiless mota ichimhanya, izvo zvinoderedza zvakanyanya kupindira kwemagetsi emagetsi paremote control redhiyo.
