Pafupipafupi converters kwa Motors kupatsidwa ulemu: Mfundo ntchito ndi kukonzanso

Lero, pafupipafupi converters kwa Motors kupatsidwa ulemu Mankhwalawa amagwiritsidwa ntchito mu makampani. Dziwani kuti injini onsewa dongosolo atatu windings awo, amene chikugwirizana pa "nyenyezi" kapena "makona". Koma iwo drawback chimodzi - kusintha ozungulira liwiro zovuta. Koma kale. Tsopano, pamene amathandiza ya zamagetsi yaying'ono ndi mphamvu, ntchito imeneyi ndi ya m'Chingelezi chosavuta. Tembenuzani resistor variable angasinthe liwiro mu osiyanasiyana.

Cholinga chimene chikufunika pafupipafupi Converter?

Nchito mankhwala zambiri, koma ambiri pang'ono ntchito. Ndipotu kulamulira galimoto asynchronous m'pofunika kuzolowera osati rotational liwiro komanso mathamangitsidwe nthawi, deceleration. Komanso, zilipo amafuna chitetezo. M'pofunika kuganizira panopa pafupipafupi Converter, amene amagwiritsa ntchito galimoto kupatsidwa ulemu.

Chimagwiritsidwa ntchito chastotniki mu kachitidwe mpweya wabwino. Ngakhale omasuka mwina gudumu fani, katundu pa ozungulira ndi aakulu kwambiri. Ndipo mathamangitsidwe yomweyo n'zosatheka. Komanso, pali zinthu zimene kufunika kuonjezera liwiro rotational, otaya mpweya anali mochuluka kapena mochepa. Koma ichi ndi chitsanzo, ndi Converter pafupipafupi kawirikawiri amagwiritsidwa ntchito machitidwe ena. Ndi chastotnika akhoza synchronize liwiro conveyor ndi, wopangidwa mwa maliboni angapo.

Mfundo ntchito kwa Converter pafupipafupi

maziko ndi microprocessor kulamulira madera kangapo akatembenuka AC ndi DC voltages. njira zingapo zimachitika ndi voteji omwe umaperekedwa kwa mphamvu athandizira chipangizo. Ntchito pafupipafupi Converter ndi yosavuta, suffices kuganizira masiteji atatu. Choyamba, pali kuwongola. Chachiwiri, zosefera. Chachitatu, inversion - kutembenuka kwa DC kuti AC.

Only pa gawo lotsiriza akhoza kusintha katundu ndi zoikamo panopa. Mwa kusinthasintha makhalidwe a panopa akhoza lizilamuliridwa ndi ozungulira liwiro la galimoto asynchronous. Mu siteji inverter ntchito zamphamvu khamu la transistors. Izi zinthu zitatu O - awiri mphamvu ndi ulamuliro wina. Ku ukulu wa chizindikiro ntchito kwa otsiriza zimadalira khalidwe panopa-voteji pa chastotnika linanena bungwe.

Kuyendetsa akhoza m'malo?

Pafupipafupi converters kwa Motors asynchronous anayamba ntchito ndi posachedwapa. Koma sayansi kenako thereto, ozungulira woyamba rotational liwiro anali zosiyanasiyana ntchito magiya kapena variator. Komabe, akulodnoleza zimenezi anali wolemera kwambiri, ndi mphamvu galimoto ali adadzonga chifukwa cha njira zosafunika. Lamba kufala amathandiza kuonjezera kasinthasintha liwiro, koma izo ziri ndendende anapereka magawo komaliza ndi zovuta. Pazifukwa izi, ndi VSD bwino kwambiri, chifukwa amapewa mphamvu imfa. Koma ambiri Chofunika - timatha inu kusintha magawo galimoto, popanda kusintha zimango.

Amene inverter kusankha ntchito kunyumba?

Tikumbukenso kuti kugwirizana akhoza kuchitika kwa maukonde one- ndi atatu gawo panopa. Izi zidalira pa galimoto chitsanzo yeniyeni, ndipo ngati mwachindunji, limene inverter dera la injini kupatsidwa ulemu ntchito kupanga. Kumvetsa mfundo ntchito, ndi okwanira kuyang'ana pa dongosolo chipangizo. Unit choyamba - ndi rectifier, zomwe zikuchitika diodes michenga yopangira zida zamagetsi. dera Izi mlatho kwa akatembenuka osakwatira kapena atatu gawo AC kwa DC. Nyumba ntchito muyenera kusankha zitsanzo chastotnikov amene zolowetsa olumikiza osakwatiwa-gawo alternating panopa. Zokhudzana zimene m'nyumba kuchititsa atatu gawo maukonde ndi mabvuto, osati ndakuwonetserani, chifukwa muyenera kugwiritsa ntchito chipangizo kwambiri chifukwa cha zipangizo za magetsi.

Kuyendetsa Gawo

Little zanenedwa kuti dera ali inverter. Koma muyenera kuganizira mwatsatanetsatane kuphunzira zambiri. M'nthawi siteji kutembenuka - AC rectification. Ziribe kanthu kuchuluka kwa gawo athandizira umaperekedwa (imodzi kapena atatu), pa linanena bungwe la rectifier inu mumapezera zonse unipolar (kuphatikiza chimodzi ndi opanda wina) voteji wa volts 220. Ndi kwambiri pakati pa gawo ndi ndale.

Pamakhala fyuluta wagawo, amene amathandiza tichotse zigawo zonse variable wa panopa kudzatha. Ndipo pa gawo lotsiriza kwambiri mozondoka - kuchokera DC ndi variable mwa transistors mphamvu, olamulidwa ndi microcontroller lapansi. Childs, inverters kwa Motors kupatsidwa ulemu ndi kuwonetsera monochrome LCD, omwe amasonyeza magawo amawathandiza.

Kodi n'zotheka kuti chipangizo nokha?

Kupanga chipangizo amagwirizana ndi mavuto ambiri. Muyenera kuphunzira ndizosowa microcontrollers mapulogalamu kuwonjezera mwayi wa chida cha. Nkofunika kuganizira zofunika zonse zoyambirira. Mwachitsanzo, basi shutdown pangozi pamene choposa pazipita chovomerezeka panopa amene ankadya ndi galimoto ndi. Kuchita izi, inu muyenera kukhala ndi mtima linanena bungwe tiransifoma panopa, umene udzakwaniritsa polojekiti mosalekeza. Komanso, ayenera kupereka yogwira ndi kungochita zinthu kuzirala kwa dongosolo mphamvu - diodes ndi transistors, ndi kuletsa chipangizo mu Kutentha kwambiri. Only mu nkhani iyi, pafupipafupi converters kwa Motors asynchronous akhoza opareshoni bwinobwino.
