1. ʻO ke kino kaʻa o kaʻO ka mīkini hoʻokalakupua DC mau loa:
ʻO ka wili ʻana o ka stator he wili koʻikoʻi, a ʻo ka rotor magnet mau loa e hoʻokumu i ke kahua mākēneki nalu huinahā;ʻO ke kino kaʻa o ka mīkini hoʻopaʻapaʻa paʻa mau: ʻo ka wili stator he wili puʻupuʻu, a ʻo ka rotor magnet paʻa e hana i kahi māla magnetic pohihihi maikaʻi;
2. Hoʻonoho ʻia ka mea ʻike o ka mīkini DC brushless:
Haʻahaʻa haʻahaʻa, 60 degere hoʻonā, Hall element, electromagnetic type, photoelectric type;ʻO ka mea ʻike kūlana o ka mīkini paʻa magnet synchronous: hoʻonā kiʻekiʻe, 1/256, 1/1024, mea hoʻonā, disk code optical;
3. Mana okoa:
Medium-nui DC mau manaʻo kaʻa uila: 120 degere huinahalike nalu o kēia manawa, me ka hoʻohana ʻana i ka mana PWM;
ʻO ke kaʻa kaʻa hoʻokalakupua mau loa: ʻO ke au o ka nalu, SPWM SVPWM mana.
Medium-sized DC permanente motor: Hoʻolima ʻia ka magnet e ka nalu huinaha, ʻo ka mana mana PWM he nalu huinaha, a ʻo ke au he nalu huinaha.Aia he 6 mau mea ho'olewa lewa i ho'okahi pō'ai uila.He maʻalahi ka mana, haʻahaʻa ke kumukūʻai, a hiki ke hoʻokō ʻia ka MCU maʻamau.
ʻO ka mīkini paʻa magnet synchronous: Hoʻohana ʻia ka magnet e kahi hawewe sine, ʻo ka ikaika electromotive hope he hawewe sine, a ʻo kēia manawa he hawewe sine.Hoʻohana maʻamau ka ʻenehana hoʻokele Vector, a aia ma ka liʻiliʻi he 18 vectors i loko o kahi pōʻai uila (ʻoiaʻiʻo, ʻoi aku ka maikaʻi), hiki ke ʻike ʻia e kahi MCU a i ʻole DSP.
DC Servo: He ākea loa kēia laulā.ʻO ka DC servo e pili ana i ka mana o ka kaʻa DC a laila ka ʻōnaehana hoʻokele, e like me nā ʻōlelo aʻoaʻo (wikiwiki, kūlana, kihi, a me nā mea ʻē aʻe) e hana, hoʻohana maʻamau no nā mea hana.
1. ʻO ka ʻokoʻa o nā mea ʻike:
Medium-sized DC permanent magnet motor (BLDC): ʻike kūlana, e like me Hall, etc.;
ʻO ka mīkini paʻa magnet synchronous (PMSM): nā mea ʻike wikiwiki a me ke kūlana, e like me nā mea hoʻonā, photoelectric encoders, etc.;
2. He okoa ka hawewe EMF hope.
BLDC: hawewe trapezoidal kokoke (kūlana kūpono);
PMSM: ʻO ka nalu kino (kūlana kūpono
ʻEkolu, ʻokoʻa ke ʻano nalu o kēia manawa:
BLDC: ka nalu huinahā a i ʻole ka nalu trapezoidal (ke kūlana kūpono);
PMSM: ʻO ka nalu kino (kūlana kūpono
ʻO ka ʻehā, ka ʻokoʻa ma waena o ka ʻōnaehana mana:
BLDC: hoʻokomo pinepine ʻia ka mea hoʻoponopono kūlana, ka hoʻoponopono wikiwiki a me ka mea hoʻoponopono o kēia manawa (torque);
PMSM: Loaʻa nā ʻōnaehana hoʻomalu like ʻole i nā ʻōnaehana mana ʻokoʻa;
5. ʻO ka ʻokoʻa ma waena o nā loina hoʻolālā a me nā ʻano hana:
BLDC: e hoʻomāhuahua i ka laula o ka nalu hope-EMF e like me ka hiki (e like me ka nalu alapiʻi);
PMSM: Hoʻopili i ka EMF hope i ka nalu sine;
Hoʻohālikelike ʻia i ka hoʻolālā ʻana ka ʻokoʻa o ka stator winding a me ka hoʻolālā rotor (e like me ka pole arc coefficient).
