I-SIMO: Ungakwehlisa kanjani ukulahleka kwemoto ye-YE3?

Lapho amandla kagesi eguqulwa abe amandla mechanical, thei-low-voltage motorngokwayo nayo izolahlekelwa ingxenye yamandla.I-LT SIMO motorkukuthatha uqonde ukulahleka kwemoto. Ukulahlekelwa kweYE3 motorzingahlukaniswa zibe izingxenye ezintathu: ukulahlekelwa okuguquguqukayo, ukulahlekelwa okugxilile kanye nokulahlekelwa okulahlekile.

1. Ukulahlekelwa okuguquguqukayo kuyahlukahluka ngomthwalo, okuhlanganisa ukulahlekelwa kokumelana kwe-stator (ukulahlekelwa kwethusi), ukulahlekelwa ukumelana ne-rotor nokulahlekelwa ukumelana nebhulashi.
2. Ukulahlekelwa okungaguquki kuzimele emthwalweni, okuhlanganisa ukulahlekelwa okuyinhloko nokulahlekelwa kwemishini. Ukulahlekelwa okuyinhloko kuhlanganisa ukulahlekelwa kwe-hysteresis kanye nokulahlekelwa kwamanje kwe-eddy, okulinganayo nesikwele se-voltage futhi ngokuphambene ngokulingana nemvamisa.
3. Okunye ukulahlekelwa okulahlekile ukulahlekelwa kwemishini nokunye ukulahlekelwa, okuhlanganisa ukulahlekelwa ukungqubuzana kwamabheringi nokulahlekelwa umoya okubangelwa ukuzungezisa kwefeni nerotha.

A. Ukulahlekelwa kwe-Stator

Izindlela eziyinhloko zokunciphisa u-1^2R ukulahleka kwe-YE3 motor stator zimi kanje:

1. Ngaphansi kobubanzi obufanayo be-stator, ukukhulisa indawo ephambanayo ye-stator slot kuzonciphisa indawo yesekethe kazibuthe futhi kwandise ukuminyana kazibuthe ezinyo.
2. Kumamotor amancane angu-YE3 ane-voltage ephansi, khulisa isilinganiso esigcwele se-slot yesikhala se-stator. Izinga le-slot eligcwele le-stator lingakhushulwa ngokuthatha usayizi ongcono wokuvunguza kanye nokufakwa kwe-insulation kanye nendawo enkulu ye-conductor cross-sectional.
3. Ukulahleka kokuphela kokujika kwe-stator kubala u-1/4~1/2 wesamba sokulahlekelwa okusongayo. Ukunciphisa ubude bokujika kokugcina kungathuthukisa ukusebenza kahle kwe-YE3 motor. Imiphumela yokuhlola ibonisa ukuthi ubude bokuphela buncishiswa ngo-20% futhi ukulahlekelwa kuncishiswa ngo-10%.

B. Ukulahlekelwa Rotor

Ukulahlekelwa kwe-1 ^ 2R kwe-YE3 motor rotor ikakhulukazi kuhlobene ne-rotor yamanje kanye nokumelana ne-rotor. Izindlela ezihambisanayo zokonga amandla zimi kanje:

1. I-rotor yamanje ingancishiswa kusuka ezicini ezimbili: ukwandisa i-voltage nokwandisa amandla we-YE3 motor;
2. Ukwandisa indawo ye-cross-sectional slot ye-rotor;
3. Enjini ye-YE3, kunengqondo kakhulu ukwehlisa ukumelana nokuvunguza kwe-rotor (njengokusebenzisa ucingo oluwugqinsi nezinto ezimelana kancane) ngoba amamotho amancane ajwayele ukuphonswa ama-aluminium rotor. Uma i-rotor yethusi ephonsiwe isetshenziswa, ukulahlekelwa okuphelele kwemoto kungancishiswa ngo-10% -15%. Kodwa-ke, izinga lokushisa lokukhiqiza le-rotor yethusi eliphonsiwe liphezulu kakhulu, ubuchwepheshe abukakaziwa, futhi izindleko zayo ziyi-15% -20% ephakeme kunaleyo ye-cast aluminium rotor.

C. Ukulahlekelwa okuyinhloko

Ukulahlekelwa kwensimbi ye-motor kungancishiswa ngezinyathelo ezilandelayo:

1. Ukuze unciphise ukuminyana kazibuthe, khulisa ubude bensimbi ukuze unciphise ukuminyana kazibuthe.
2. Isibonelo, ukujiya kweshidi lensimbi ye-silicon bungancishiswa ngokusebenzisa ishidi lensimbi ye-silicon egoqelwe ngokubanda esikhundleni seshidi lensimbi ye-silicon egoqwe ngokushisayo, kodwa amashidi ensimbi azacile azokhuphula inani lamashidi ensimbi kanye nezindleko zokwenziwa kwezimoto.
3. Sebenzisa ishidi le-silicone eligoqiwe elibandayo eline-conductivity enhle ukunciphisa ukulahleka kwe-hysteresis.
4. Sebenzisa ukusebenza okuphezulu kwe-iron chip insulation coating.
5. Ukwelashwa kokushisa nobuchwepheshe bokukhiqiza, ingcindezi esele ngemuva kokucutshungulwa kwe-iron chip izothinta kakhulu ukulahleka kwemoto. Lapho ucubungula ishidi lensimbi ye-silicon, isiqondiso sokusika kanye nokucindezeleka kokugunda kwe-shear kunethonya elikhulu ekulahlekelweni kwensimbi. Ukusika eceleni kokuqondisa kwe-silicon steel sheet kanye nokushisa okwelapha i-silicon steel sheet kunganciphisa ukulahlekelwa ngo-10% ~ 20%.

D. Ukulahlekelwa okulahlekile

Okwamanje, ukuqondwa kokulahlekelwa okungaqondile kwe-YE3Injini ye-AC isesigabeni socwaningo

1. Ukwelashwa kokushisa nokuqedwa kusetshenziselwa ukunciphisa i-rotor surface short circuit.
2. Indawo engaphakathi ye-rotor slot is insulated.
3. Kuthuthukiswe idizayini yokujika kwe-stator ukuze kuncishiswe ama-harmonics.
4. Ngokuthuthukisa umklamo ofanayo kanye nokumataniswa kwe-rotor slots, ukwandisa i-stator kanye ne-rotor slots, ukuklama izikhala ze-rotor zibe yi-skew Slots, nokusebenzisa i-sinusoidal windings, ama-winding ahlakazekile kanye ne-pitch windings emfushane ochungechungeni, ukuhleleka okuphezulu kwe-harmonics kungancishiswa kakhulu. Ngokusebenzisa udaka lwegebe kazibuthe noma ama-gap wedges azibuthe esikhundleni se-gap wedges yendabuko, futhi ugcwalise izikhala ze-stator core ye-motor ngodaka lwegebe kazibuthe, kuyindlela ephumelelayo yokunciphisa ukulahlekelwa okungeziwe okulahlekile.

E. Ukulahlekelwa ukungqubuzana komoya

Ukulahleka kokushayisana komoya kubala cishe amaphesenti angama-25 okulahleka okuphelele kwemoto futhi kufanele kunakwe. Ukulahleka kwefriction kubangelwa ikakhulukazi ama-bearings nama-seal, futhi ukulahlekelwa ukungqubuzana kungancishiswa ngezinyathelo ezilandelayo:

1. Ubukhulu be-shaft kufanele buncishiswe ngangokunokwenzeka, kodwa kufanele buhlangabezane nezidingo zokukhishwa kwe-torque kanye ne-rotor dynamics.
2. Sebenzisa ama-bearings asebenza kahle kakhulu.
3. Sebenzisa amasistimu okugcoba nama-lubricant asebenzayo.
4. Sebenzisa ubuchwepheshe bokuvala uphawu obusezingeni eliphezulu.
