Kugwiritsa ntchito Asynchronous Motor

Ma asynchronous motors omwe amagwira ntchito ngati ma motors amagetsi. Chifukwa mafunde a rotor amapangitsidwa, amatchedwanso induction motor. Ma Asynchronous motors ndi omwe amagwiritsidwa ntchito kwambiri komanso ofunidwa kwambiri pamitundu yonse yama mota. Pafupifupi 90% ya makina oyendetsedwa ndi magetsi m'maiko osiyanasiyana ndi ma asynchronous motors, omwe ma asynchronous motors amakhala opitilira 70%. Pakuchulukirachulukira kwamagetsi, kugwiritsa ntchito magetsi kwa ma asynchronous motors kumakhala gawo lalikulu. Ku China, kugwiritsa ntchito magetsi kwa ma asynchronous motors kumapitilira 60% ya katundu wonse.

Lingaliro la mota ya asynchronous

Asynchronous motor ndi injini ya AC yomwe chiŵerengero cha liwiro la katunduyo mpaka mafupipafupi a gridi yolumikizidwa simtengo wokhazikika. Motor induction ndi mota ya asynchronous yokhala ndi ma windings amodzi okha olumikizidwa ndi magetsi. Pankhani yakusayambitsa kusamvana ndi chisokonezo, ma induction motors amatha kutchedwa ma asynchronous motors. Muyezo wa IEC umanena kuti mawu oti "induction motor" amagwiritsidwa ntchito ngati mawu ofanana ndi "asynchronous motor" m'maiko ambiri, pomwe mayiko ena amangogwiritsa ntchito mawu oti "asynchronous motor" kuyimira malingaliro awiriwa.

Mfundo ya injini ya asynchronous

Pambuyo voteji symmetrical ntchito kwa stator mapiringidzo wa atatu gawo asynchronous galimoto, ndi kasinthasintha mpweya kusiyana maginito ndi kwaiye, ndi wozungulira chokhotakhota kondakitala amadula maginito kuti apange mphamvu anachititsa. Mphamvu ya rotor imapangidwa chifukwa cha kufupika kwa mafunde a rotor. Kulumikizana pakati pa ma rotor pano ndi mpweya wozungulira maginito kumapanga torque yamagetsi, yomwe imayendetsa rotor kuti izungulira. Liwiro la mota liyenera kukhala lotsika kuposa liwiro lolumikizana la maginito, chifukwa ndi njira iyi yokha yomwe woyendetsa wa rotor angapangire mphamvu yamagetsi kuti ipange ma rotor pano ndi maginito amagetsi. Chifukwa chake injiniyo imatchedwa makina asynchronous, omwe amatchedwanso induction motor.
