E kamaʻilio ana e pili ana i ka ikaika electromotive hope o ka mīkini paʻa paʻa synchronous

1. Pehea e hana ʻia ai ka ikaika electromotive hope?

Kapa ʻia ka ikaika electromotive hope. Kumu: ʻoki ka mea alakaʻi i nā laina magnetic o ka ikaika.

ʻO ka rotor o ka motor synchronous magnet paʻa he magnet mau loa, a ua ʻeha ka stator me nā coils. I ka wā e hoʻololi ai ka rotor, ʻoki ʻia ke kahua magnetic i hana ʻia e ka magnet mau loa e nā coils ma ka stator, e hana ana i ka mana electromotive hope ma ka coil (ma ka ʻaoʻao ʻē aʻe i ka volta terminal U).

2. Ka pilina ma waena o ka ikaika electromotive hope a me ka voltage terminal

3. ʻO ke ʻano kino o ka ikaika electromotive hope

Back EMF: hoʻopuka i ka ikehu pono a hoʻopili like ʻia me ka nalowale wela (e hōʻike ana i ka hiki ke hoʻololi o ka mea uila).

4. Ka nui o ka ikaika electromotive hope

Hōʻuluʻulu:

(1) Ua like ka EMF hope me ka nui o ka hoʻololi ʻana o ka flux magnetic. ʻO ke kiʻekiʻe o ka wikiwiki, ʻoi aku ka nui o ka loli a ʻoi aku ka nui o ka EMF hope.

(2) Ua like ka flux pono'ī me ka helu o nā huli i hoʻonui ʻia e ka flux i kēlā me kēia huli. No laila, ʻoi aku ka kiʻekiʻe o ka helu o nā huli, ʻoi aku ka nui o ka flux a ʻoi aku ka nui o ka EMF hope.

(3) Ua pili ka helu o na huli i ka wiliwili, pili hōkū-delta, ka helu o ka huli ma ka slot, ka helu o na pae, ka helu o na niho, ka helu o na lala like, a me ka piha-pitch a pōkole paha;

(4) Ua like ka hoʻololi ʻana hoʻokahi me ka ikaika magnetomotive i puʻunaue ʻia e ke kūpaʻa magnetic. No laila, ʻoi aku ka nui o ka ikaika magnetomotive, ʻoi aku ka liʻiliʻi o ke kūpaʻa magnetic i ke kuhikuhi o ka flux a ʻoi aku ka nui o ka ikaika electromotive hope.

(5) Pili ke kū'ē magnetic i ka ea a me ka hoʻonohonoho pole-slot. ʻOi aku ka nui o ka ea, ʻoi aku ka nui o ke kūpaʻa magnetic a me ka liʻiliʻi o ka ikaika electromotive hope. He paʻakikī ka hoʻohui ʻana o ka pole-slot a pono i ka nānā ʻana;

(6) Pili ka ikaika magnetomotive i ke koena magnetism o ka magnet a me ka wahi kūpono o ka magnet. ʻO ka nui o ke koena magnetism, ʻoi aku ka kiʻekiʻe o ka ikaika electromotive hope. ʻO ka'āpana kūpono e pili ana i ke kuhikuhi magnetization, ka nui a me ka hoʻokomoʻana o ka magnet, e koi ana i ka nānā pono;

(7) Pili pū ka remanence i ka mahana. ʻO ke kiʻekiʻe o ka mahana, ʻoi aku ka liʻiliʻi o ka EMF hope.

I ka hōʻuluʻulu ʻana, ʻo nā mea e pili ana i ka EMF e pili ana i ka wikiwiki o ka huli ʻana, ka helu o ka huli ʻana i kēlā me kēia slot, ka helu o nā pae, ka helu o nā lālā parallel, piha piha a me ka pitch pōkole, kaapuni magnetic kaʻa, ka lōʻihi o ka ea, ka hoʻohālikelike ʻana i ka pole-slot, ka hoʻomau ʻana o ke kila magnetic, ka hoʻokomo kila kila a me ka nui, ka kuhikuhi ʻana o ke kila kila, a me ka mahana.
