Synchronous na asynchronous moto: ọdịiche, ọrụ ụkpụrụ, na ojiji nke

Nhazi ọkwa engine dabeere na dị iche iche kwa. Otu n'ime ha, ịmata ọdịiche dị n'etiti synchronous na asynchronous Motors. Iche ngwaọrụ, n'ozuzu e ji mara na mode nke ọrụ na-kọwara na isiokwu.

synchronous moto

Nke a na ụdị engine bụ ike na-arụ ọrụ ma dị ka a generator na dị nnọọ engine. Ya na ngwaọrụ yiri a synchronous generator. A mara mma nke moto bụ invariable ọsọ nke adiana nke rotary ibu.

Ndị a na ụdị engines na-ọtụtụ-eji ọtụtụ ubi, dị ka eletriki wires, nke mkpa a mgbe nile na-agba.

Ụkpụrụ nke ime ihe nke synchronous moto

Ndabere nke ya ọrụ dị mkpa na mmekọrịta nke n'usoro ndọta nke armature na ndọta nke inductor okporo osisi ya. A, arịlịka emi odude ke stator, na ihe inductor-etinye on a rotor. N'ihi na elu-ike Motors eji electric nju ka okporo osisi, na na-adịghị ike - na-adịgide adịgide.

The na-arụ ọrụ ụkpụrụ nke synchronous moto-agụnye (nwa oge) na ihe asynchronous mode, nke na a na-eji achụsakwa na achọrọ (i.e. elu ọnụ) ọsọ. N'oge a, inductor asọfe ma ọ bụ obere-circuited site a rheostat. Mgbe na-eru ndị chọrọ ọsọ nke inductor amalite na-eri nri a mgbe nile ugbu a.

Uru na ụkọ ihe ụfọdụ

Isi ọghọm nke ụdị engine bụ:

• mkpa-ezitekwara asọfe DC;
• ike malite;
• eji kọntaktị.

Kasị generators, n'ebe ọ bụla ha na-eji, na-synchronous. The uru nke ndị dị otú engines n'ozuzu nọ:

• kasị elu pụrụ ịdabere;
• kasị ukwuu arụmọrụ ;
• mfe nke mmezi.

itinye n'ọkwa moto

Nke a na ụdị ustroysta usoro a na-iji na-enwogha eletriki ume nke nwetụ ugbu a n'ime n'ibu ike. Site aha ya, "asynchronous", anyị nwere ike ikwubi na anyị na-ekwu okwu banyere aka ike usoro. N'ezie, ndị stator ndọta adiana ugboro bụ mgbe niile n'elu rotor.
Ndị dị otú ahụ a na ngwaọrụ ndị mejupụtara a stator na a rotor nke cylindrical udi, na-adabere n'ụdị onye asynchronous osa-onu Motors nwere ike emerụ rotor.

ụkpụrụ nke ime ihe

na moto dabeere na na mmekọrịta nke magnetik n'ubi nke stator na-egosi na otu ubi ugbu a na rotor. The torque na-adị mgbe e nwere a dị iche na-agba ubi.

Ugbu a ichikota ihe dị iche n'etiti synchronous moto asynchronous. Gịnị na-akọwa nile iji otu ụdị na-ejedebeghị - ọzọ?

Synchronous na asynchronous Motors: iche

N'adịghị ka engines ọrụ - na rotor. Na synchronous ụdị, ọ bụ a mgbe nile ma ọ bụ onye electric magnet. N'ihi na Push-Sere abụghị okporo osisi nke stator n'usoro ubi ma na-eburu magnetik rotor. Ha na-agba na-enwetara yiri. N'ihi ya, aha - synchronous.

Ọ nwere ike na-enweta, na iche asynchronous, ọbụna na-aga n'ihu na n'ụzọ voltaji. Mgbe ahụ ngwaọrụ, dị ka batrị capacitor nwere ike etinyere ntọt ike.

Itinye n'ọkwa Motors, n'aka nke ya, bụ ndị dị mfe ma a pụrụ ịdabere, ma ha mwepu bụ ike nke ukpụhọde ọsọ. Iji laa azu-adọ itinye n'ọkwa moto (i.e., na-agbanwe ntụziaka nke adiana-ya nile na-abụghị uzo) mgbanwe ọnọdụ nke abụọ n'ụzọ ma ọ bụ abụọ linear eduzi eru nso stator asọfe.

Ọ bụrụ na anyị na-atụle rotational ọsọ, na mgbe ahụ nwere ebe a a synchronous na asynchronous moto iche. Na synchronous ụdị, a ọnụ ọgụgụ a mgbe nile, na iche na itinye n'ọkwa. Ya mere, onye mbụ ji mee ebe dị mkpa mgbe nile na-agba na full controllability, e.g., na nfuli, Fans na compressors.

Enweta na a akpan akpan ngwaọrụ, ọnụnọ nke na-atụle ụdị ngwaọrụ dị nnọọ mfe. Na itinye n'ọkwa moto ga-a gburugburu ọnụ ọgụgụ nke revolutions (atụ, narị itoolu na iri atọ kwa nkeji), ebe maka synchronous - gburugburu (e.g., a puku revolutions kwa nkeji).

Ndị na ndị ọzọ na moto draịva bụ nnọọ ihe siri ike. A synchronous ụdị nwere a isiike e ji mara na-arụzi ụgbọala maka ihe ọ bụla mgbanwe ibu na moto aro ọsọ bụ otu ihe ahụ. Na nke a, ibu na-, n'ezie, ga-agbanwe echiche nke eziokwu ahụ bụ na engine bụ ike idi ya, ma ọ ga imebi usoro.

Nke ahụ bụ ụzọ synchronous na asynchronous Motors. Iche n'etiti abụọ na ụdị ime ka akporo nke ha were, mgbe otu ụdị ịnagide ozi optimally, nye ndị ọzọ ọ ga-abụ mfịna. N'otu oge ahụ i nwere ike izute na jikọtara usoro.
