Karuwan AMINCI, rage kudin da kuma sauki sarrafa tabbatar babu inji sharuddan sauyawa abubuwa, na'ura mai juyi windings kuma m maganadiso. Wannan karuwa a yi shi ne zai yiwu ta rage da frictional hasarori a cikin haraji tsarin. A brushless motor iya aiki a wani alternating ko m halin yanzu. A karshe zaɓi ne daban-daban sananne kama da da commutator mota. Its halayyar alama ne da samuwar wani juyawa Magnetic filin da ake ji a pulsed halin yanzu. Ya dogara ne a kan lantarki canji ne ba, saboda wanda qara wuya daga cikin zane.

Lissafi na matsayi

bugun jini tsara faruwa a kula da tsarin, bayan wata sigina nuna da matsayi na na'ura mai juyi. Daga cikin mota juyawa kai tsaye swiftness mataki na danniya da kuma ciyar dogara.

Domin na'ura mai juyi maganadisu da m halin yanzu Summing optionally, inda babu asara a cikin na'ura mai juyi Tuddan. Brushless motor ga sukudireba yana da wani low matakin na inertia, tabbatar babu windings kuma mechanized haraji. Saboda haka, da damar amfani a high gudu ba tare da ya haifar da electromagnetic amo. A high dabi'u na halin yanzu da kuma simplification zafi masha'a samu ta ajiye dumama kewaye a stator. Shi ne kuma ya kamata a lura da gaban da gina-in lantarki naúrar a kan wasu model.

Magnetic abubuwa

Location na maganadiso na iya bambanta daidai da engine size, misali, a kan ko a kusa da sandunan da na'ura mai juyi. Samar da ingancin maganadiso na tare da karin iko ne yiwu godiya ga yin amfani da neodymium a hade tare da boron, da baƙin ƙarfe. Duk da karfi aiki yi, brushless motor ga sukudireba da m maganadisu yana da wasu disadvantages, ciki har da asarar da Magnetic halaye a high yanayin zafi. Amma su ne ya fi dacewa, kuma babu asarar a kwatanta da inji a gina wanda yana windings.

A inverter hatsaisai sanin ko juyawa gudun da inji. A m wadata mita na mota aiki ne da za'ayi a wata m gudun a cikin wani bude madauki tsarin. Haka kuma, da rotational gudun dabam dangane da matakin da wadata mita.

halaye na

Bawul motor aiki a wani kwari jihar da kuma yana da wani aikin analogue goga wanda gudu ya dogara da aiyuka irin ƙarfin lantarki. The inji yana da yawa abũbuwan amfãni:

• babu canji a magnetization da yayyo halin yanzu.
• daidai da na rotational gudu da kuma karfin juyi.
• gudun ba iyakance ta centrifugal karfi da shafi cikin tara da Rotary lantarki Tuddan.
• babu bukatar canza da kuma zumudi Tuddan.
• maganadiso na amfani ne hur kuma m.
• high karfin juyi.
• makamashi jikewa da kuma yadda ya dace.

A brushless DC mota tare da m maganadisu na faruwa musamman cikin na'urorin da damar a cikin kewayon 5 kW. A wani more iko hardware su yi amfani da impractical. Har ila yau, ya kamata a lura shi ne cewa maganadiso a Motors na irin wannan ne musamman m zuwa high yanayin zafi da kuma karfi filayen. Shigar da kuma goga embodiments bã tãre da drawbacks. A injuna suna yadu amfani da lantarki babura, motor tafiyarwa saboda babu gogayya a tafki. Daga cikin siffofin zama dole don zaɓar uniformity na karfin juyi da kuma na yanzu, wanda rage audible amo.
