Asynchronous moto: imewe na ngwa

Atọ-adọ asynchronous moto na osa onu echepụta azụ na 1889, 8 March, ama Russian ọkà mmụta sayensị na engineer Mikhail Osipovich Dolivo-Dobrovolsky. Ugbua na dị nnọọ a afọ, December 15, 1890, e chepụta na patented moto na ileghara-mgbanaka Motors.

Atọ-adọ asynchronous moto - otu n'ime ihe ndị kasị eletriki ngwaọrụ na njem. Ọ dị mfe iji rụọ ọrụ, a pụrụ ịdabere na na nwere a pụtara ala price. Asynchronous moto-ewe fọrọ nke nta ka iri itoolu percent nke ngụkọta ọnụ ọgụgụ nke engines n'ụwa nile. Ọ pụrụ ịchọta fọrọ nke nta n'ebe nile - na imewe nke a ot saa igwe, ruo nnukwu ulo oru ụlọ ahịa, ghara ikwu ike. O mere ka a oké ụzụ mgbanwe na ụwa nke ụlọ ọrụ.

Asynchronous moto - a igwe na e mere iji tọghata eletriki ume n'ibu ike. "Asynchronous" pụtara nanị "bụghị synchronous". Ọ na-ghọtara na ndị dị otú ahụ a igwe ugboro ole nke a n'usoro n'usoro ndọta N'ịbụ stator, ga-adị ukwuu karịa nke ọnụego ya na nke na-agbagharị ibughari nke moto - rotor.

Asynchronous moto mejupụtara a ofu akụkụ - na stator na ibughari n'usoro akụkụ - na rotor.

The stator na-kpọkọtara si Ibé akwụkwọ nke abịakọrọ eletriki nchara na a nwere a cylindrical udi. The grooves nke isi na-stacked stator asọfe ka nke asọfe waya. Stator windings na a ole na ole. Data asọfe axis n'ozuzu gbanwere site n'akuku nke 120 degrees ikwu ọ bụla ọzọ. Nsọtụ ndị a windings nwere ike jikọọ na kpakpando ma ọ bụ Delta (dabere na nke voltaji na-etinyere).

The rotors nwere ndị dị otú a igwe, dị ka itinye n'ọkwa moto, na ndị na-adịghị circuited adọ.

The mbụ ụdị (a mkpụmkpụ-circuited rotor) - a isi nke a na-kpọkọtara si ọla kọpa ma ọ bụ aluminum mkpara tọrọ nime ya asọfe. The mkpara jikọọ ọgwụgwụ yiri mgbaaka, na ha dị yiri a osa onu. Site n'ụzọ, otú a rotor pịnye mgbe kwuru na dị ka "osa-onu". The rotor bụ na nke a ọzọ anakọtara site na eletriki ígwè Ibé akwụkwọ, enwe ma wụsa aluminum.

Adọ rotor a na-akpọkarị rotor ileghara mgbanaka. Ọ nwere ihe atọ na-adọ asọfe, nke bụ n'ezie ezi dị iche iche si stator windings. Ihu ọma, na nsọtụ nke windings nke rotor ileghara mgbanaka (adọ) ejikọrọ na a kpakpando. The free nsọtụ jikọọ na ileghara yiri mgbaaka si otú. The asọfe circuit a na-kwukwara ọzọ resistor n'ihi ọnụnọ nke pụrụ iche brushes, jikọọ na yiri mgbaaka. Ndị dị otú ahụ a resistor enwekwu ndị na-eguzogide na rotor circuit, nke na-eme ka a smoother amalite na ọnụ ụkpụrụ inrush ugbu a - ọ dị ezigbo mkpa maka ígwè ọrụ dị otú ahụ, dị ka atọ-adọ asynchronous Motors.
