SIMO: Ukunciphisa njani ilahleko yemoto ye-YE3?

Xa amandla ombane aguqulwa abe ngamandla oomatshini, iinjini ene-voltage ephantsingokwayo nayo iya kulahlekelwa inxalenye yamandla.Injini ye-LT SIMOithatha ukuba uqonde ukulahleka kwemoto. Ilahleko yeYE3 imotoinokwahlulwa ibe ngamacandelo amathathu: ilahleko eguquguqukayo, ilahleko esisigxina kunye nelahleko elahlekileyo.

1. Ilahleko eguquguqukayo iyahluka kunye nomthwalo, kubandakanywa ukulahlekelwa kwe-stator (ukulahleka kobhedu), ukulahlekelwa kwe-rotor ukumelana nokulahlekelwa kwe-brush.
2. Ilahleko esisigxina izimeleyo kumthwalo, kubandakanywa ukulahlekelwa okungundoqo kunye nokulahlekelwa ngumatshini. Ilahleko engundoqo ibandakanya ilahleko ye-hysteresis kunye nelahleko yangoku ye-eddy, ehambelana nesikwere sombane kwaye ihambelane ngokungafaniyo nobuninzi.
3. Enye ilahleko elahlekileyo yilahleko yoomatshini kunye nezinye iilahleko, kubandakanya ukulahleka kwefriction yeebheringi kunye nokulahleka komoya okubangelwa kukujikeleza kwefeni kunye nerotor.

A. Ilahleko yeStator

Ezona ndlela ziphambili zokunciphisa i-1^2R ilahleko ye-YE3 motor stator zezi zilandelayo:

1. Ngaphantsi kwedayimitha yangaphandle yestator efanayo, ukwandisa indawo enqamlezayo ye-stator slot kuya kunciphisa indawo yesekethe yamagnetic kwaye kwandise ukuxinana kwezinyo.
2. Kwiimotor ezincinci ze-YE3 ezisezantsi, yongeza ubungakanani obugcweleyo be-slot ye-stator slot. Umlinganiselo ogcweleyo we-slot westator unokunyuswa ngokwamkela ukujikajika okungcono kunye nobukhulu bokufakelwa kunye nommandla omkhulu we-conductor cross-sectional.
3. Ukuphela kwelahleko ye-stator yokuvala i-akhawunti ye-1/4 ~ 1/2 yelahleko ejikelezayo iyonke. Ukunciphisa ubude besiphelo somoya kunokuphucula ukusebenza kakuhle kwemoto ye-YE3. Iziphumo zovavanyo zibonisa ukuba ubude bokugqibela buncitshiswe nge-20% kwaye ilahleko iyancipha nge-10%.

B. Ilahleko yeRotor

I-1 ^ 2R ilahleko ye-YE3 ye-motor rotor inxulumene kakhulu ne-rotor yangoku kunye nokumelana ne-rotor. Iindlela ezihambelanayo zokonga umbane zezi zilandelayo:

1. I-rotor yangoku ingancitshiswa kwimiba emibini: ukwandisa i-voltage kunye nokwandisa amandla ombane we-YE3;
2. Ukwandisa indawo ye-cross-sectional slot ye-rotor;
3. Kwimoto ye-YE3, iyavakala ngakumbi ukunciphisa ukuxhathisa kwe-rotor winding (efana nokusebenzisa ucingo olungqingqwa kunye nezinto ezixhathisayo eziphantsi) kuba iinjini ezincinci zihlala ziphosa iirotha zealuminiyam. Ukuba i-rotor yobhedu isetyenzisiwe, ilahleko iyonke yemoto ingancitshiswa nge-10% -15%. Nangona kunjalo, ukushisa kwemveliso ye-rotor yobhedu ephosiweyo kuphezulu kakhulu, iteknoloji ayikabonakali, kwaye iindleko zayo ziyi-15% -20% ephezulu kune-rotor ye-aluminium.

C. Ilahleko engundoqo

Ilahleko yentsimbi yenjini inokuncitshiswa ngala manyathelo alandelayo:

1. Ukuze kuncitshiswe ukuxinana kwemagnethi, nyusa ubude bombindi wentsimbi ukunciphisa ukuxinana kwemagnethi.
2. Umzekelo, ubukhulu beshiti lentsimbi ye-silicon buya kuncitshiswa ngokusebenzisa i-silicon eqengqelekayo epholileyo endaweni ye-silicon yentsimbi eshushu, kodwa iitshiphusi zentsimbi ezibhityileyo ziya konyusa inani leetshiphusi zentsimbi kunye neendleko zokwenziwa kweemoto.
3. Sebenzisa i-silicone yentsimbi epholileyo ene-conductivity elungileyo ukunciphisa ilahleko ye-hysteresis.
4. Sebenzisa umgangatho ophezulu wokugquma wentsimbi.
5. Unyango lobushushu kunye netekhnoloji yokuvelisa, uxinzelelo olushiyekileyo emva kokusetyenzwa kwe-iron chip kuya kuchaphazela kakhulu ilahleko yemoto. Xa kusetyenzwa ishidi lensimbi ye-silicon, isalathiso sokusika kunye noxinzelelo lokucheba ngenqindi kunempembelelo enkulu ekulahlekeni kwentsimbi. Ukusika ecaleni kwendlela yokuqengqeleka ye-silicon yentsimbi kunye nobushushu bonyango lwe-silicon sheet sheet kunokunciphisa ilahleko nge-10% ~ 20%.

D. Ilahleko elahlekileyo

Okwangoku, ukuqondwa kwelahleko elahlekileyo ye-YE3Injini ye-AC isekwinqanaba lophando

1. Ukunyanga ukushisa kunye nokugqiba kusetyenziselwa ukunciphisa i-rotor surface short circuit.
2. Umphezulu wangaphakathi we-rotor slot is insulated.
3. Ukuphuculwa koyilo lwe-stator winding ukunciphisa i-harmonics.
4. Ngokuphucula idizayini ehambelanayo kunye nokudibanisa i-rotor slots, ukwandisa i-stator kunye ne-rotor slots, ukuyila i-rotor slots kwi-skew slots, kunye nokusebenzisa i-sinusoidal windings, i-dispersed windings kunye ne-short pitch windings kwi-series, i-harmonics yomyalelo ophezulu ingancitshiswa kakhulu. Ngokusebenzisa udaka lwemagnethi ye-gap okanye i-gap wedges ye-magnetic gap wedges endaweni ye-gap wedges yendabuko, kunye nokuzalisa izithuba ze-stator core ye-motor ngodaka lwemagnetic gap, yindlela esebenzayo yokunciphisa ilahleko eyongezelelweyo elahlekileyo.

E. Ilahleko yokungqubana nomoya

Ilahleko yokruthakruthwano lomoya malunga ne-25% yelahleko iyonke yemoto kwaye kufuneka ithathelwe ingqalelo. Ilahleko yefriction ibangelwa ikakhulu ziibheringi kunye netywina, kwaye ilahleko yefriction inokuncitshiswa ngala manyathelo alandelayo:

1. Ubungakanani be-shaft kufuneka buncitshiswe ngokusemandleni, kodwa kufuneka buhlangabezane neemfuno ze-torque yokuphuma kunye ne-rotor dynamics.
2. Sebenzisa iibheringi eziphezulu.
3. Sebenzisa iinkqubo ezifanelekileyo zokuthambisa kunye nezithambiso.
4. Sebenzisa iteknoloji yokutywina ephezulu.
