Zomwe zimayambitsagawo atatu AC galimotokuwotcha kumatha kugawidwa mu katundu, mphamvu zamagetsi, zotsekemera zamagalimoto, ndi kutayika kwa gawo.
Kutentha kwa magawo atatu a AC motor (mochulukira): Pogwira ntchito mochulukira, mota imatenthetsa. Kapena injini imayamba pafupipafupi ndipo injiniyo imatentha kwambiri. Pamene malekezero onse a stator atenthedwa mkati mwa galimoto ndipo mbali zowotchedwa zimakhala zofanana (nthawi zambiri, galimotoyo imakhala ndi mphamvu yogwiritsira ntchito nthawi zonse, yotchedwa mphamvu yovotera, mu Watts (w), ndipo nthawi zina mphamvu yeniyeni yogwiritsidwa ntchito ndi galimotoyo imaposa mphamvu ya galimoto, izi zimatchedwa motor overload. Zomwe zimachititsa kuti magawo atatu a AC awonongeke kwambiri, mphamvu yamagetsi imakhala yocheperapo, mphamvu yamagetsi imakhala yochepa kwambiri, mphamvu yamagetsi imakhala yocheperapo, mphamvu yamagetsi imakhala yotsika kwambiri Kutentha kwambiri. Mphamvu yamagetsi ndiyokwera kwambiri, ndipo makina a barbecue akuyaka kapena kutayika kwa gawo.
Zomwe zimayambitsa magawo atatu a AC motor insulation: Kutsekera kwamkati kwa injini sikungafanane ndi muyezo, ndipo pali gawo lalifupi lozungulira pakati pa kutembenuka. Kapena mawaya amkati ndi olakwika. Makina a barbecue nthawi zina amasokonezeka mosavuta ndi makina a barbecue ochulukira, ndipo stator nawonso amawotcha, koma pali zipsera zowonekera pagawo lalifupi, monga miyala yamkuwa yosungunuka nthawi zina. Mbali yokhotakhota yatenthedwa kwambiri. Zifukwa zoyaka moto wa magawo atatu a AC ndi: 1. Thegalimoto yamagetsiamatenga akulumikizana kwa delta (gawo 3)njira, ndi gawo limodzi lokha la mapiringidzo akhoza kuwotchedwa. Gwiritsani ntchito megohmmeter kuyeza kuwonongeka kwa gawo limodzi la mapindikidwe pansi. 2. Galimoto imatenga njira yolumikizira nyenyezi (y), ndipo magawo awiri a mafunde amawotchedwa. Mutha kugwiritsa ntchito megohmmeter (wotchi) kuyeza kuwonongeka kwa magawo awiri a mapindikidwe apansi.
