Asynchronous injini: magadzirirwo midziyo

Three-danho asynchronous injini ine tsindi keji yagadzirwa shure muna 1889, musi 8 March, yakakurumbira musayendisiti wokuRussia uye injiniya Mikhail Osipovich Dolivo-Dobrovolsky. Nechekare chete pagore, December 15, 1890, yakanga yakagadzirwa uye patented injini ine pitikoti-mhete Motors.

Three-danho asynchronous injini - chimwe chezvinhu zvakafanana magetsi mano ari indasitiri. Zviri nyore kuti ishande, hwakavimbika uye ane zvakanaka yakaderera mutengo. Asynchronous injini kunotora inenge mapfumbamwe kubva muzana uwandu injini munyika yose. Rinogona kuwanikwa kusvika kose - kubva magadzirirwe munhu kwakajairika wokuwachisa, kusvikira guru maindasitiri zvitoro, tisingatauri simba. Akaita guru rwokugadzira yechimurenga munyika indasitiri.

Asynchronous injini - muchina zvakagadzirirwa kutendeutsa zvemagetsi simba kupinda zvokuimba simba. "Asynchronous" kunongoreva "kwete synchronous". Zvinonzi kunzwisiswa kuti vakadaro muchina kakawanda ine kutenderera remagineti kunotangira ari stator, kucharamba kupfuura mwero panguva iyo rotates ari chinjwa chikamu injini - rotor.

Asynchronous injini ine yakatarwa chikamu - the stator uye chinjwa kutenderera chikamu - the rotor.

The stator iri vakaungana kubva machira ane compressed zvemagetsi simbi uye yemanyorero ane cylindrical chimiro. The grooves ari chinoumba iri ukapisa murwi stator ichitenderera chakagadzirwa ichitenderera waya. Stator windings panguva shoma. Data ichitenderera akabatana kazhinji zvava pedyo necheparutivi rworwendo 120 hama kune mumwe. Migumo windings izvi kunogona kwakabatana munguva nyeredzi kana Delta (zvichienderana iro voltage rikashandiswa).

The rotors vane muchina yakadai, sezvo induction injini, uye vane pfupi-circuited kutotanga.

Mhando wokutanga (a pfupi-circuited rotor) - panozogadzirika riri vakaungana kubva mhangura kana aruminiyamu tsvimbo vakaisa mairi ichitenderera. Matanda vari zvakabatana magumo marin'i, uye chitarisiko chavo chakafanana tsindi keji. Zviya, saka rotor ichi kutaipa kakawanda vachinzi "tsindi-keji". The rotor iri nyaya iyi zvakare inounganidzwa kubva magetsi simbi machira, chakatsindirwa ugodira aruminiyamu.

Danho rotor unowanzonzi rotor pitikoti mhete. It ane-danho matatu ichitenderera, riri chaizvoizvo rakasiyana stator windings. Zvikurukuru, kumugumo windings ari rotor pitikoti mhete (danho) zvakabatana mune nyeredzi. The vakasununguka Migumo chokuita kuti pitikoti marin'i napo. The ichitenderera Dunhu iri kazhinji akawedzera mamwe resistor nokuda pamberi dzinokosha brushes, chokuita zvindori. mumwe resistor kwakadaro anowedzera kurwisa iri rotor redunhu, iro rinoita kuti munhu unotedza pokutangira uye kuderera tsika inrush kuitika - zvakakosha zvikuru kuti michina yakadaro, akadai-danho matatu asynchronous Motors.
