No kamotika ʻekolu-paepae, ʻelua ʻano pilina o ka wili stator, triangle a me ka hōkū, ʻo ka pilina hōkū ka hoʻohui ʻana i ka huelo o ka wili ʻekolu-paepae, a ua pili ke poʻo o ka wili ʻekolu-paepae me ka lako mana; ʻO ke ʻano pilina hōkū he ʻelua mau hihia o ka pilina malihini a me ka pilina kūloko, ʻo ka motika pilina hōkū kūloko ʻo ia ka kiko hōkū i hoʻopili ʻia me ka wili ʻekolu-paepae i hoʻopaʻa ʻia ma ka ʻāpana kūpono o ka wili stator, aia ʻekolu mau wēlau puka e alakaʻi ana i waho, a ʻo ka pilina malihini ʻo ia ke poʻo a me ka huelo o ka wili ʻekolu-paepae i alakaʻi ʻia i waho, a me ka pilina waho a me nā uwea o ka motika.
ʻO ke ʻano hoʻohui triangular, ʻo ia ka hoʻohui ʻana i ke poʻo o kahi wili pae me ka huelo o kahi wili pae ʻē aʻe, ʻo ia hoʻi, ʻo U1 a me W2, V1 a me U2, W1 a me V2, a ua pili ke kiko hoʻohui i ka lako mana.
Inā manaʻo ʻia kēlā me kēia wili pae e like me kahi laina, ma hope o ka hoʻopili ʻia ʻana o nā hōkū, ua like ia me kahi hōkū ʻālohilohi, a ua like ke kānāwai pili triangle me kahi triangle, no laila ua kapa ʻia ʻo ia ka pilina hōkū a i ʻole ka pilina triangle. Hiki iā mākou ke hoʻohui i ka motika triangle i ʻelua mau hihia o ke kihi kūloko a me ke kihi waho.
Inā he motika hoʻokahi-voltage, hiki ke hoʻopili ʻia i loko a me waho, akā no ka motika pālua-voltage, hiki ke huki ʻia ke poʻo a me ka huelo o ka wili ʻekolu-phase, a laila e hoʻokō ʻia ka pilina waho e like me ke kūlana voltage, a ʻo ke kiʻekiʻe o ke voltage e pili ana i ka pilina hōkū a ʻo ke voltage haʻahaʻa e pili ana i ka pilina Angle.
No ke aha e hoʻohana ai i ka pilina hōkū no nā mīkini uila kiʻekiʻe：
No nā motika haʻahaʻa haʻahaʻa, e hoʻokaʻawale ʻia e like me ka mana, e like me ke ʻano kumu o nā motika e like me ka mahele 3kW, ʻaʻole i ʻoi aku ma mua o 3kW e like me ka pilina hōkū, ʻo kekahi e like me ka pilina Angle, a nonā mīkini alapine loli, e like me ka mahele 45kW, ʻaʻole iʻoi aku ma mua o 45kW e like me ka pilina hōkū, ʻo kekahi e like me ka pilina Angle; No nā mīkini hāpai a me nā mīkini metallurgical, ʻoi aku ka nui o nā hui hōkū, a e hoʻohana pū nā mīkini hāpai nui i nā hui Angle. ʻO ke kaʻa uila kiʻekiʻe he ʻano pilina hōkū maʻamau, ʻo ke kumu e pale aku i ka wili ʻana o ke kaʻa e kū i ke uila kiʻekiʻe. I ka pilina hōkū, ua like ke au laina me ke au pae, a ʻo ke au laina he 3 manawa ke kumu o ke au pae (i ka pilina triangle, ua like ke au laina me ke au pae a ua like ke au laina me ka√3 mau manawa o ke au pae), no laila ua haʻahaʻa loa ke au i lawe ʻia e ka wili motika. I nā motika uila kiʻekiʻe, he liʻiliʻi pinepine ke au, a ʻoi aku ke kiʻekiʻe o ka pae insulation o ke motika, no laila ʻoi aku ka maikaʻi o ka mālama ʻana i ka insulation o ke motika pili hōkū a ʻoi aku ka hoʻokele waiwai.
