Nrụpụta moto dc na-enweghị brush

moto na-enweghị brush dcỌdịdị imewe bụ nnọọ ihe ezi uche dị na ya, site n'iji ya mee ihe anyị nwere ike n'ụzọ doro anya na-eche ya ojiji, uru nke ezi uche Ọdịdị dị mfe iji, ngwa ngwa ọrụ, anyị nwere ike ịhụ otú elu aku na uba uru na-eji uru ezi uche structure.So gịnị bụ usoro ya?

Nke mbụ, leba anya na nhazi ya:

1. A, B na C bụ atọ-phase stator windings, nke a na-otu n'otu jikọọ na ike mgba ọkụ ngwaọrụ V1, V2 na V3 na electronic mgba ọkụ sekit.A na-etinye rotor tracking nke ihe mmetụta ọnọdụ na rotor nke moto.VP1, VP2 na VP3 na-ekesa nke ọma n'otu njedebe nke brushless dc moto nwere ọdịiche nke 120 degrees.Dị ka ụfọdụ ngwaọrụ fotoelectric si dị, a na-eme ka ọkụ na-egbuke egbuke ma ọ bụ na ọ bụghị site na ọrụ nke mkpuchi na-atụgharị na moto na-agbagharị agbagharị.

2, stator winding nke A nkịtị eletriki, eletriki ugbu a na isi magnetik na-emepụta site na-adịgide adịgide magnets na rotor n'ihi na mmekọrịta n'etiti electromagnetic torque na rotor rotor, ọnọdụ nke rotor magnet ígwè na ọnọdụ ihe mmetụta n'ime eletriki mgbaàmà, na mgbe ahụ ịchịkwa electronic mgba ọkụ circuit, nke mere na onye ọ bụla na-adọ winding nke stator ga-n'aka, conduction, stator frasi ugbu a tinyere mgbanwe nke rotor ọnọdụ na A ụfọdụ iji commutation.The conduction usoro nke electronic mgba ọkụ circuit nwere ike ịbụ. mekọrịtara ya na akụkụ ntụgharị nke rotor iji nweta mmetụta ntụgharị igwe.

N'ihi na a na-edozi usoro moto brushless dc n'ụzọ ezi uche dị na ya, ya mere ọ dị ezigbo mma iji, na usoro nke ọrụ moto, na mgbakwunye na ịghọta usoro ya, anyị kwesịkwara ime ka mmetụta ntụgharị ya dịkwuo mma, ndị a bụ n'ụzọ bụ isi wuru na ndabere nke ezi uche Ọdịdị.
