Uma kuqhathaniswa nama-rotor amanxeba, ama-cage rotors anekhwalithi engcono kakhulu nokuphepha, kodwa ama-cage rotors azoba nezinkinga zekhwalithi ezimweni ezivame ukuqala kanye ne-inertia enkulu yokujikeleza.
Uma sikhuluma nje, ukuthembeka kwekhwalithi ye-cast aluminium rotors kungcono, imigoqo ye-rotor ihlanganiswe kahle ne-rotor core, futhi amandla okumelana nokukhiqizwa kokushisa ngesikhathi sokuqalisa imoto kunamandla. Kodwa-ke, iziphambeko zekhwalithi ezifana nezimbobo ezinciphayo kanye nemigoqo emincane eyenzeka ngesikhathi sokuphonswa kwe-aluminium, kanye nenkinga yokuphulwa kwe-bar okubangelwa ukushisa kwe-rotor ayikwazi ukushaywa indiva, ikakhulukazi esimweni sezinto ezimbi zebha kanye nenqubo yokuphonsa i-aluminium embi, inkinga inkulu kakhulu.
Uma kunenkinga nge-cast aluminium rotor, ngokuvamile ingahlulelwa kusukela ngaphandle kwe-rotor kanye nezinye izenzakalo zekhwalithi. Uma i-rotor inenkinga yebha ephukile, izoshisa kakhulu, futhi indawo ye-rotor izoba nesenzakalo esicacile se-blueing ngokwengxenye noma ngokuphelele. Ezimweni ezimbi kakhulu, kuzoba nobuhlalu obuncane be-aluminium obakhiwe ukugeleza kokushisa. Le nkinga ivame ukuvela engxenyeni emaphakathi yebha. Lapho i-aluminium cast rotor ishisa, indandatho yokuphela kwe-rotor nayo izokhubaza. Ezimweni ezimbi kakhulu, ama-wind blades ekupheleni kwe-rotor azophonswa ngaphandle kwe-radially futhi alimaze i-stator winding.
Kuma-rotor we-squirrel cage kabili, ama-rotor groove ajulile, ama-rotor amise okwebhodlela, njll., asetshenziselwa ukuthuthukisa ukusebenza kokuqala, uma ama-rotor bars ephuka, indawo yokuphuka ngokuvamile ivela endaweni yokushisela eduze nendandatho yokugcina. Ukuphulwa kwe-rotor bar kungenxa yemiphumela ephindaphindiwe yokucindezeleka okushisayo kwesikhathi eside, ukushintsha amandla kagesi kagesi, amandla e-centrifugal kanye nokucindezeleka kwe-tangential, okuzobangela ukugoba nokukhathala kokulimala emigoqweni. Imigoqo namandandatho okugcina kungenzeka ukuthi abe nezinkinga. Ngesikhathi senqubo yokuqala yemoto, ngenxa yomphumela wesikhumba, imigoqo ye-rotor ishisa ngokulinganayo, futhi imigoqo ye-rotor ingaphansi kokucindezeleka okugoba ku-axis; lapho i-motor isebenza ngokujwayelekile, imigoqo ye-rotor nezindandatho zokugcina zingaphansi kwamandla we-centrifugal, futhi imigoqo ikhiqiza ukucindezeleka okugoba kude ne-axis. Lezi zingcindezi zizosongela ukuthembeka kwazo zombili iziphetho ze-rotor bar. Ukuze kuthuthukiswe ikhwalithi ye-rotor welding, ubuchwepheshe be-medium-frequency brazing busetshenziswe kancane kancane kwinqubo yokushisela yama-rotors amakhulu.
