Bakeng sa ho ntlafatsa boleng ba koloi, lilemong tsa morao tjena, lerata la motlakase le kenyelelitsoe ho e 'ngoe ea matšoao a tlhahlobo ea boleng, haholo-holo bakeng sa tikoloho ea ts'ebetso ea likoloi le ho kopana le batho haufi le boemo, lerata la motlakase le fetohile ditlhoko tsa kelo tsa bohlokwa haholo.
E le hore u laoleenjene ea asynchronouslerata, ho phaella ho moralo oa stator le rotor slot ka khetho e nepahetseng ea stator le rotor slot ntle le slant slot e ka sebelisoa ho fokotsa lerata la motlakase oa motlakase. Empa ha e le hantle hore na moepa o lekaneng hakae, ho hlokahala liteko tse ling ho netefatsa.
Ka kakaretso, letsoapo la rotor slot ea li-asynchronous motors li ka nkuoa e le leqhubu le le leng la leino la stator, leo le lona le ka fihlelang litlhoko. Leha ho le joalo, e le hore u ntlafatse lerata la motlakase ka ho eketsehileng, ho hlokahala hore u hlahlobe moepa o nepahetseng oa slot, o hlokang palo e kholo ea lipalo le ho netefatsa.
E hlahlobjoa ho tloha ponong ea tlhahiso, tlhahiso e otlolohileng ea motlakase le ts'ebetso e batla e le bonolo, empa ha ho hlokahala, e tla hloka ho ba stator slot kapa rotor slot torsion. The stator slot torsion e batla e le thata, ka hona, maemong a mangata, rotor slot tilting. Rotor slot torsion ka kakaretso ka ts'ebetso ea ts'ebetso ea shaft ea tsela ea senotlolo ho fihlela, likhoebo tse tsoetseng pele tsa lisebelisoa, ts'ebeliso ea li-spiral punching, ts'ebetsong ea tlhahiso ea mantlha ea rotor ho fihlela.
Lerata la electromagnetic le baka le mehato ea ho qoba
Lerata la enjene esale e le bothata bo boima ho rarolloa, haholo-holo le hlahisoa ke mabaka a mararo a motlakase, mochini, moea le moea. Lerata la motlakase ka har'a enjene ea asynchronous le bakoa ke maqhubu a stator le rotor sekheong sa moea se thehiloeng ho harmonic magnetic field interaction le electromagnetic force wave e bakoang ke ho thothomela ha joko ea mantlha, ho qobella ho potoloha.tsitsinyeho ya moyale hlahiswa. Lebaka le ka sehloohong ke ka lebaka la ho se tšoane ha slot, stator le rotor eccentricity kapa lekhalo le lenyenyane haholo la moea.
Lerata la motlakase le bakoa ke tsitsipano ea makenete e etsang liphetoho nakong le sebaka 'me e sebelisoa ke likarolo tse fapaneng tsa enjene. Ka hona, bakeng sa li-asynchronous motors, lisosa tsa sebopeho sa lerata la motlakase li kenyelletsa:
● Maqhubu a matla a mahlaseli sebakeng sa lekhalo la moea a etsa hore radial e fetohe le ho sisinyeha nako le nako ha stator le rotor.
● Maqhubu a matla a mahlaseli a matla a phahameng a har'a lekhalo la moea la khoheli a sebetsa ho stator le rotor cores, a etsa hore li fetohe radial deformation le ho thothomela nako le nako.
● The deformation of different order harmonics of the stator core e na le maqhubu a fapaneng a ka hare, 'me resonance e bakoa ke ha maqhubu a maqhubu a matla a mahlaseli a le haufi kapa a lekana le e' ngoe ea maqhubu a hare-hare a mantlha.
Deformation ea stator e etsa hore moea o potolohileng o thothomele, 'me boholo ba lerata la motlakase ke lerata la mojaro.
Ha mokokotlo o tletse, karolo ea boraro ea harmonic ea eketseha, 'me lerata la motlakase lea eketseha.
Li-slots tsa stator le rotor kaofela li bulehile, 'me ho na le "maqhubu a ho buloa ha slot" a hlahisoang tlas'a ts'ebetso ea matla a matla a maqhubu moeeng oa matla a khoheli,' me lekhalo le lenyenyane la moea, le leholo le le leholo, le leholo.
E le ho qoba bothata, ofisi e sethaleng sa moralo oa sehlahisoa ka mekhoa e meng e atlehang ea ho ntlafatsa, e kang: ho khetha tekanyo e utloahalang ea matla a khoheli, ho khetha mofuta o nepahetseng oa ho phalla le palo ea litsela tse amanang le eona, eketsa palo ea stator. ho phunya li-slots, ho fokotsa coefficient ea kabo ea harmonic ea windings ea stator, ts'ebetso e nepahetseng ea koloi ea stator-rotor air gap motor, ho khetha stator le rotor groove ka rotor slant groove, tšebeliso ea rotor, le mehato e meng e khethehileng.
