He aha ka brushless motor—-hana hana

Hoʻohana ʻia kahi mīkini uila DC brushless (BLDC motor a i ʻole BL motor) i nā mea hoʻololi semiconductor e ʻike i ka commutator uila, ʻo ia hoʻi, nā mea hoʻololi uila ma kahi o ka commutator contact kuʻuna a me ka brush. a laila.Hoʻohana nui ʻia ia i ka noho hoʻopaʻa kiʻekiʻe kiʻekiʻe, ka mea hoʻopaʻa leo wikiō, nā mea uila a me nā lako automation keʻena.

ʻO ke kaʻa uila DC ʻole ua haku ʻia me ka rotor magnet mau loa, ka stator wili ʻana he nui a me ka ʻike kūlana. Ke ʻike ʻana i ke kūlana e like me ka hoʻololi ʻana o ke kūlana rotor, me kekahi kaʻina o ka mea hoʻololi i kēia manawa stator winding (ʻo ia hoʻi ka ʻike ʻana i ka pou magnetic rotor pili i ke kūlana o ka wili stator. , a ma ka hoʻoholo 'ana i ka wahi o ka hoʻololi 'ana i ka hoailona, ​​ka hoailona hoololi kaapuni e hoomalu i ka mana kuapo kaapuni, ma hope o ka hana ana e like me kekahi logic pili ma waena o wili i kēia manawa kuapo). ma ka puka ana o ka mea ike kulana.

ʻEkolu mau ʻano o nā mea ʻike kūlana: magnetic-sensitive, photoelectric a me electromagnetic.

Brushless DC motor me ka magnetic-sensitive position sensor, kona mau ʻāpana sensor magnetic-sensitive (e like me ka hall element, magnetic-sensitive diode, magnetic-sensitive pole tube, magnetic-sensitive resistor or special integrated circuit, etc.) ua kau ʻia ma ka stator. hui e ʻike i ka hoʻololi ʻana o ke kahua magnetic i hoʻokumu ʻia e ka magnet mau a me ka rotation rotor.

ʻO ka brushless DC motor me ka photoelectric position sensor ua hoʻolako ʻia me ka photoelectric sensor ma kahi kūlana ma ka hui stator, hoʻokomo ʻia kahi pale ma ka rotor, a alakaʻi ʻia ke kumu kukui a i ʻole ka puʻupuʻu liʻiliʻi. o ka mea pani, e hoopuka pinepine na mea photosensitive ma ka stator i na hoailona pulse ma kekahi alapine.

Me ka hoʻohana ʻana i ke kūlana electromagnetic brushless dc motor, aia i loko o ka electromagnetic sensor i hoʻokomo ʻia ma nā ʻāpana stator (e like me ka mea hoʻololi hoʻohui, kokoke i ka hoʻololi, LC resonance circuit, a me nā mea ʻē aʻe), ke hoʻololi ke kūlana magnet rotor mau, e hopena ka hopena electromagnetic. hana i ka mea ʻike electromagnetic e hana i ka hōʻailona modulation kiʻekiʻe (e hoʻololi ka amplitude me ke kūlana rotor)

Loaʻa iā JIUYUAN ma mua o 20 mau makahiki ʻike maliʻiliʻi brushless dc motor,waho rotor brushless dc motor,i loko o lokor brushless dc motor.
