Algorithm no AC brushless motor a me ka mīkini palaki AC

• Ka hoʻomalu ʻana

ʻO ka mana Scalar (a i ʻole ka mana V/Hz) he ala maʻalahi ia o ka hoʻokele ʻana i ka wikiwiki o kahi kaʻa aʻo
Hoʻohana nui ʻia ke ʻano hoʻohālikelike o ke kaʻa kauoha no ka loaʻa ʻana o ka ʻenehana, no laila ʻaʻole hiki ke hana transient. ʻAʻohe loop loop o ka ʻōnaehana.

• Ka mana vector a i ʻole ka mana hoʻokele kahua

ʻOkoʻa ka torque i loko o ke kaʻa me ka hana o ka stator a me ka rotor magnetic field a hiki i kona kiʻekiʻe i ka wā o nā māla magnetic ʻelua i orthogonal kekahi i kekahi.
Ke ho'āʻo nei ka mana Vector e hana hou i ka orthogonality i nā kaʻa AC.
Ua like ka mana vector o kahi kaʻa kaʻa kauoha AC me ka ʻenekini DC hauʻoli. IA.These magnetic fields ua decoupled a paʻa i kekahi i kekahi. No laila, i ka wā e hoʻomaluʻia ai ke au o ka armature e hoʻomalu i ka torque,ʻaʻole i hoʻopiliʻia ka ikehu a me ka wikiwiki o ka pane transient.
ʻO ka mana hoʻonaʻauao kahua (FOC) o kahi motika AC ʻekolu-phase e pili ana i ka hana e hoʻohālike ana i ka motika DC. Hoʻololi makemakika ʻia nā ʻano hoʻololi āpau i DC ma kahi o AC.

• ʻElua mau ala o ka mana hoʻokele kahua (FOC):

ʻO FOC pololei: ua helu pololei ʻia ka Angle flux Rotor e ka mea nānā flux
FOC Indirect: Loaʻa ka Angle Flux Rotor ma ke koho ʻana a i ʻole ke ana ʻana i ka wikiwiki o ka Rotor a paheʻe.
Pono ka mana o Vector i ka hoʻomaopopo ʻana i ke kūlana o ka rotor flux a hiki ke helu ʻia me ka hoʻohana ʻana i nā algorithms holomua e pili ana i ka ʻike o ka hopena o kēia manawa a me ka volta (e hoʻohana ana i nā hiʻohiʻona ikaika o nā motika induction AC). he mea koʻikoʻi ka hoʻopili ʻana i nā kumuwaiwai.

Hiki ke hoʻokō ʻia ka algorithm vector control ma nā ʻano like ʻole. Hiki ke hoʻohana ʻia nā ʻenehana Feedforward, ka manaʻo hoʻohālike, a me nā ʻenehana mana adaptive no ka hoʻomaikaʻi ʻana i ka pane a me ke kūpaʻa.

JIUYUAN loaʻa nā ʻenehana loea me nā makahiki 20 o ka ʻike maliʻiliʻi brushless dc motor,waho rotor brushless dc motor,i loko o lokor brushless dc motor, ʻoi aku ke kaʻa DC brushless, kaʻaʻa dc brushless me ka mea hoʻokele a i ʻole ka hoʻokele, ka mīkini palaki ʻole AC a me ka mīkini palaki AC etc.Kāhea iā mā˚ouno ka ʻike kikoʻī.
