ʻO nā kumu oʻekolu ʻāpana AC motorHiki ke hoʻokaʻawale ʻia ka burnout i ka ukana, ka lako mana, ka insulation kaʻa, a me ka nalowale ʻana.
ʻEkolu mau ʻāpana kaʻa kaʻa AC (ʻoi aku ka nui) pau ʻana: Ma lalo o ka hana ʻoi loa, wela ke kaʻa. A i ʻole e hoʻomaka pinepine ka kaʻa a wela ke kaʻa. Ke puhi ʻia nā ʻaoʻao ʻelua o ka stator i loko o ke kaʻa a lilo nā ʻāpana i puhi ʻia (ma ka ʻōlelo maʻamau, he mana hana mau ka kaʻa, kapa ʻia ka mana helu, ma watts (w), a i kekahi mau mea, ʻoi aku ka mana maoli i hoʻohana ʻia e ka kaʻa ma mua o ka mana helu o ka kaʻa, ua kapa ʻia kēia ʻano i ka overload motor. He kiʻekiʻe loa ka uila, a ke ʻā nei ka mīkini barbecue a i ʻole ke holo ʻana o ke kaʻa me ka pau ʻana o kēia kūlana He mea maʻalahi a maʻalahi hoʻi e hoʻokolokolo, no ka mea, aia nā māka ma ka laina.
ʻO nā kumu o ka hoʻokaʻawale ʻana i ka ʻenekini AC ʻekolu-phase: ʻAʻole i kūpono ka insulation kūloko o ke kaʻa i ka maʻamau, a aia kahi kaapuni pōkole ma waena o nā huli. A i ʻole he hewa ka uwea kūloko. ʻO kēia mīkini barbecue i kekahi manawa maʻalahi huikau me ka overload barbecue machine, a me ka stator e hoʻopau ʻia, akā aia nā hōʻailona kuni ma ka ʻāpana pōkole, e like me ke keleawe i hoʻoheheʻe ʻia i kekahi manawa. ʻO ka ʻāpana wili ua puhi ʻino ʻia. ʻO nā kumu o ke ahi ʻana o ka motika AC ʻekolu ʻāpana: 1. ʻO kakaʻa uilahāpai i kapili delta (3 pae)ala, a hoʻokahi wale nō māhele o ka wili ʻana hiki ke puhi ʻia. E hoʻohana i ka megohmmeter e ana i ka pōʻino insulation o hoʻokahi māhele o ka wili ʻana i ka honua. 2. Hoʻohana ka motika i ke ʻano hoʻohui hōkū (y), a puhi ʻia nā ʻāpana ʻelua o ka wili. Hiki iā ʻoe ke hoʻohana i ka megohmmeter (uaki) e ana i ka pōʻino insulation o nā ʻāpana ʻelua o ka wili ʻana i ka honua.
