Kusiyana pakati pa ma mota a asynchronous ndi a synchronous

1. Mfundo yogwirira ntchito:
Mfundo yogwirira ntchito ya mota yopanda mphamvu imachokera pa mfundo yogwirira ntchito ya mota yolowetsa mphamvu. Pamene rotor ya mota yopanda mphamvu yakhudzidwa ndi mphamvu ya maginito yozungulira, mphamvu yamagetsi yopangidwa imapangidwa mu mota yolowetsa mphamvu, yomwe imapanga mphamvu, zomwe zimapangitsa kuti rotor iyambe kuzungulira. Mphamvu yamagetsi iyi imachitika chifukwa cha mayendedwe pakati pa rotor ndi mphamvu yamagetsi yozungulira. Chifukwa chake, liwiro la rotor ya mota yopanda mphamvu nthawi zonse limakhala lotsika pang'ono kuposa liwiro la mphamvu yamagetsi yozungulira, ndichifukwa chake imatchedwa mota "yopanda mphamvu".
Mfundo yogwirira ntchito ya mota yolumikizana imachokera pa mfundo yogwirira ntchito ya mota yolumikizana. Liwiro la rotor ya mota yolumikizana limagwirizanitsidwa ndendende ndi liwiro la mphamvu ya maginito yozungulira, chifukwa chake imatchedwa mota "yolumikizana". Ma mota olumikizana amapanga mphamvu ya maginito yozungulira kudzera mu mphamvu yosinthasintha yolumikizidwa ndi mphamvu yakunja, kotero kuti rotor ikhozanso kuzungulira mofanana. Ma mota olumikizana nthawi zambiri amafuna zida zakunja kuti rotor igwirizane ndi mphamvu ya maginito yozungulira, monga mafunde akumunda kapena maginito okhazikika.

2. Makhalidwe a kapangidwe kake:
Kapangidwe ka mota yopanda mphamvu ndi kosavuta ndipo nthawi zambiri kamakhala ndi stator ndi rotor. Pali ma winding atatu pa stator omwe amasunthidwa ndi magetsi ndi madigiri 120 kuchokera kwa wina ndi mnzake kuti apange mphamvu ya maginito yozungulira kudzera mu alternating current. Pa rotor nthawi zambiri pamakhala kapangidwe kosavuta ka copper conductor komwe kamayambitsa mphamvu ya maginito yozungulira ndikupanga torque.
Kapangidwe ka mota yolumikizana ndi ma synchronous ndi kovuta, nthawi zambiri kumaphatikizapo stator, rotor ndi system yosonkhezera. System yosonkhezera ikhoza kukhala gwero lamagetsi la DC kapena maginito okhazikika, omwe amagwiritsidwa ntchito popanga mphamvu yamagetsi yozungulira. Nthawi zambiri pamakhala ma windings pa rotor kuti alandire mphamvu yamagetsi yopangidwa ndi system yosonkhezera ndikupanga torque.

3. Makhalidwe a liwiro:
Popeza liwiro la rotor la mota yopanda mphamvu nthawi zonse limakhala lotsika pang'ono kuposa liwiro la mphamvu ya maginito yozungulira, liwiro lake limasintha malinga ndi kukula kwa katundu. Pansi pa katundu woyesedwa, liwiro lake lidzakhala lotsika pang'ono kuposa liwiro loyesedwa.
Liwiro la rotor la mota yolumikizana limagwirizana kwathunthu ndi liwiro la mphamvu ya maginito yozungulira, kotero liwiro lake ndi lokhazikika ndipo silimakhudzidwa ndi kukula kwa katundu. Izi zimapatsa ma mota olumikizana kukhala abwino kwambiri pakugwiritsa ntchito komwe kumafunika kuwongolera liwiro molondola.

4. Njira yowongolera:
Popeza liwiro la mota yopanda mphamvu limakhudzidwa ndi katundu, zida zina zowongolera nthawi zambiri zimafunika kuti pakhale kuwongolera liwiro molondola. Njira zodziwika bwino zowongolera zimaphatikizapo kulamulira liwiro losinthira ma frequency ndi kuyamba mofewa.
Ma mota ogwirizana amakhala ndi liwiro losasintha, kotero kuwongolera kumakhala kosavuta. Kuwongolera liwiro kumatha kuchitika mwa kusintha mphamvu yamagetsi kapena mphamvu ya maginito ya maginito okhazikika.

5. Madera ogwiritsira ntchito:
Chifukwa cha kapangidwe kake kosavuta, mtengo wotsika, komanso koyenera kugwiritsa ntchito mphamvu zambiri komanso mphamvu zambiri, ma mota a asynchronous amagwiritsidwa ntchito kwambiri m'mafakitale, monga kupanga mphamvu zamphepo, mapampu, mafani, ndi zina zotero.
Chifukwa cha liwiro lake losasintha komanso mphamvu zake zowongolera molondola, ma mota ogwirizana ndi oyenera kugwiritsa ntchito omwe amafunikira kuwongolera liwiro molondola, monga majenereta, ma compressor, malamba otumizira, ndi zina zotero m'makina amphamvu.

Kawirikawiri, ma mota osasinthasintha ndi ma mota ogwirizana ali ndi kusiyana koonekeratu pa mfundo zawo zogwirira ntchito, makhalidwe a kapangidwe kake, makhalidwe a liwiro, njira zowongolera ndi magawo ogwiritsira ntchito. Kumvetsetsa kusiyana kumeneku kungathandize kusankha mtundu woyenera wa injini kuti ikwaniritse zosowa zinazake zaukadaulo.
