He aha nā pono o ka motika kīʻaha hakahaka ma mua o ka motika dc maʻamau

ʻO ke ʻano o ka motika kīʻaha hakahaka e uhaʻi i ka ʻano rotor kuʻuna o ka motika, me ka hoʻohana ʻana i kahi rotor coreless, i ʻike ʻia hoʻi ʻo ka rotor kīʻaha hakahaka. Hoʻopau loa ka ʻano rotor hou i ka pohō mana i hoʻokumu ʻia e ke au eddy i hoʻokumu ʻia e ke kumu. No laila he aha nā pono o nā motika kīʻaha hakahaka ma mua o ka maʻamaunā motika dc?

Motika Haʻalulu Kālā

He aha nā pono o ka motika kīʻaha hollow?

1. Ka nui o ka mana

ʻO ka mānoanoa o ka mana ka lakio o ka mana hoʻopuka i ke kaumaha a i ʻole ka nui. ʻO ka mīkini wili keleawe liʻiliʻi ka nui, hana maikaʻi. Ke hoʻohālikelike ʻia me ka wili kuʻuna, ʻoi aku ka māmā o ke kumu hoʻohālike wili keleawe. Me ka ʻole o ka wili ʻana a me ke grooving ʻana i ka pepa kila silicon, ua hoʻopau ʻia ka eddy current a me ka pohō hysteresis i hoʻokumu ʻia e lākou. He liʻiliʻi loa ka pohō o ke au eddy i ke ʻano wili keleawe-plate a maʻalahi hoʻi e kaohi, kahi e hoʻomaikaʻi ai i ka pono o ka mīkini a hōʻoia i ka torque a me ka mana hoʻopuka kiʻekiʻe.

2. Kūpono

ʻO ka pono o ka motika aia ma ka ʻoiaʻiʻo ʻaʻohe o ka eddy current a me ka pohō hysteresis o ka wili keleawe i hoʻokumu ʻia e ka wili ʻana a me ke grooving silicon steel sheet. Eia kekahi, he liʻiliʻi ke kū'ē, e hōʻemi ana i ka pohō keleawe.

3. ʻAʻohe hysteresis torque

ʻO ke ʻano wili keleawe me ka ʻole o ka pepa kila silicon groove, ʻaʻohe pohō hysteresis, ʻaʻohe hopena groove niho e hōʻemi i ka wikiwiki a me nā fluctuations torque.

4. ʻAʻohe hopena slot

Hana ʻia ke koʻi keleawe i ke kila silicon me ke ʻano ʻole o ka groove, kahi e hoʻopau ai i ka hopena groove i hoʻokumu ʻia e ka pilina ma waena o ke groove a me ka magnet. He hale ka coil me ka ʻole o kahi hao. Hoʻohuli pū nā ʻāpana kila āpau (e like me ke kaʻa palaki) a i ʻole e paʻa (e like me ke kaʻa brushless). ʻAʻole maopopo ka hopena slot a me ka torque hysteresis.

5. ʻAʻohe ikaika radial ma waena o ka rotor a me ka stator

ʻOiai ʻaʻohe kikowaena ferrite paʻa, ʻaʻole hiki ke loaʻa ke kahua magnetic axial ma waena o ka rotor motika a me ka stator motika. He mea koʻikoʻi loa kēia i nā noi koʻikoʻi. Ma muli o ka ikaika axial ma waena o ka rotor motika a me ka stator motika, ʻaʻole paʻa ka rotor motika. ʻO ka hōʻemi ʻana i ka ikaika axial e hoʻomaikaʻi i ka hilinaʻi o ka rotor motika.

6. ʻO ka piʻo wikiwiki a me ka walaʻau haʻahaʻa

ʻAʻohe kumu ferrite grooved, kahi e hoʻemi ai i ka harmonic o ka mamao rotation a me ka voltage hana. No ka mea ʻaʻole hiki ke loaʻa ke kahua AC i loko o ka motika, ʻaʻohe walaʻau i hoʻokumu ʻia e AC. ʻO ka walaʻau wale nō mai nā bearings rolling a me nā cyclones a me ka haʻalulu mai nā ʻano nalu non-sinusoidal.

7. Ka hopena hoʻopuehu wela maikaʻi

ʻO ka ʻōwili solenoid kālā keleawe i loko a ma waho o ka ʻili he pinepine ka wai kinoea, ʻoi aku ka maikaʻi ma mua o ka hoʻoheheʻe wela o ka paipu wela ma mua o ka ʻōwili solenoid rotor motor slot. Hoʻokomo ʻia ke kaula silika kuʻuna i loko o ke kahawai o ka ferrite core. He kakaikahi loa nā cyclones ʻili i loko o ka ʻōwili electromagnetic. No ka mana like, ʻoi aku ka liʻiliʻi o ka mahana o ke ʻano o ka ʻōwili electromagnetic kālā keleawe.
