Xa i-motor iguqula amandla ombane kumandla ombane, ilahlekelwa yinxalenye yamandla ngokwawo. Ngokubanzi, ilahleko yemoto inokwahlulwa ibe ngamacandelo amathathu: ilahleko eguquguqukayo, ilahleko esisigxina kunye nelahleko elahlekileyo.

1. Ilahleko eziguquguqukayo ziyahlukahluka kunye nomthwalo, kubandakanywa ukulahlekelwa kwe-stator (ukulahleka kobhedu), ukulahlekelwa kwe-rotor ukumelana nokulahlekelwa kwe-brush.

2. Ukulahlekelwa okusisigxina kuxhomekeke kumthwalo, kubandakanywa nokulahlekelwa kwengundoqo kunye nokulahlekelwa ngumatshini.Ilahleko yentsimbi yenziwe yilahleko ye-hysteresis kunye nelahleko yangoku ye-eddy, ehambelana nesikwere sombane, kwaye ilahleko ye-hysteresis iphinda ilingane ngokuphindaphindiweyo.

3. Enye ilahleko elahlekileyo yilahleko yoomatshini kunye nenye ilahleko, kubandakanywa ukulahleka kwefriction yeebheringi kunye nelahleko yokuxhathisa umoya okubangelwa kukujikeleza kweefeni kunye neerotha.

Ukuhlelwa kwelahleko yeMoto

Amanyathelo amaninzi okunciphisa ilahleko yeeMoto

1 Ilahleko yeStator

Iindlela eziphambili zokunciphisa i-I^2R ilahleko ye-motor stator zezi:

1. Yandisa indawo enqamlezileyo yestator slot. Ngaphantsi kwedayimitha yangaphandle efanayo ye-stator, ukwandisa indawo enqamlezayo ye-stator slot kuya kunciphisa indawo yesekethe yamagnetic kwaye kwandise ukuxinana kwamazinyo.

2. Ukwandisa umlinganiselo opheleleyo we-slots we-stator slots, ongcono kwiinjini ezincinci ze-voltage. Ukusebenzisa eyona ndlela ilungileyo yokujija kunye nobungakanani bokufakelwa kunye nocingo olukhulu olunqamlezileyo lwendawo kunokunyusa ubungakanani obugcweleyo be-slot yestator.

3. Zama ukunciphisa ubude besiphelo se-stator. Ilahleko ye-stator yokuvala isiphelo yenza i-1/4 ukuya kwi-1/2 yelahleko ejikelezayo iyonke. Ukunciphisa ubude besiphelo somoya kunokuphucula ukusebenza kakuhle kwemoto.Iimvavanyo zibonisa ukuba ubude bokugqibela buncitshiswa nge-20% kwaye ilahleko iyancipha nge-10%.

2 ilahleko Rotor

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

1. Nciphisa i-rotor yangoku, enokuthi ithathelwe ingqalelo ngokunyuka kwe-voltage kunye ne-motor power factor.

2. Ukwandisa indawo enqamlezayo ye-rotor slot.

3. Nciphisa ukuxhathisa kwe-rotor winding, njengokusebenzisa iingcingo ezishinyeneyo kunye nezixhobo ezinokuxhathisa okuphantsi, okunentsingiselo ngakumbi kwiinjini ezincinci, kuba iimotor ezincinci zidla ngokuphoswa iirotor ze-aluminium, ukuba zisetyenzisiwe iirotor zobhedu, ilahleko iyonke ye-aluminiyam. i-motor inokwehliswa nge-10% ～15%, kodwa i-rotor yobhedu yanamhlanje ifuna ukushisa okuphezulu kokuvelisa kwaye iteknoloji ayikadumi, kwaye ixabiso layo li-15% ukuya kwi-20% ephezulu kune-rotor ye-aluminium.

3 Ilahleko engundoqo

Ilahleko yentsimbi yenjini inokuncitshiswa ngala manyathelo alandelayo:

1. Nciphisa ukuxinana kwamagnetic kwaye ukwandise ubude bombindi wentsimbi ukunciphisa ukuxinana kwemagnethi, kodwa isixa sentsimbi esetyenziswa kwimotor sanda ngokufanelekileyo.

2. Nciphisa ubukhulu bephepha lentsimbi ukunciphisa ilahleko ye-current induced current. Umzekelo, ukutshintsha i-silicon sheet yentsimbi eshushu eqengqelekayo kunye neshiti yentsimbi eqengqelekayo yesilicon inokunciphisa ubukhulu beshiti lentsimbi yesilicon, kodwa ishidi lentsimbi elibhityileyo liya konyusa inani lamaphepha entsimbi kunye neendleko zokwenziwa kwemoto.

3. Sebenzisa i-silicone yentsimbi epholileyo epholileyo enokungena kakuhle kwemagnethi ukunciphisa ilahleko ye-hysteresis.

4. Yamkela i-high-performance iron insulation chip coating.

5. Ukunyangwa kobushushu kunye neteknoloji yokuvelisa, uxinzelelo olushiyekileyo emva kokucutshungulwa kwentsimbi yentsimbi kuya kuchaphazela kakhulu ukulahlekelwa kwemoto. Xa kusetyenzwa ishidi lensimbi ye-silicon, isalathiso sokusika kunye noxinzelelo lokucheba ngenqindi kunempembelelo enkulu kwilahleko engundoqo.Ukusika ecaleni kwendlela yokuqengqeleka ye-silicon yentsimbi kunye nonyango lobushushu lwe-silicon steel punching sheet kunokunciphisa ilahleko nge-10% ukuya kwi-20%.

4 Ilahleko elahlekileyo

Namhlanje, ukuqondwa kweelahleko zemoto kusekho kwinqanaba lophando. Ezinye zeendlela eziphambili zokunciphisa ilahleko elahlekileyo namhlanje zezi:

1. Sebenzisa unyango lokushisa kunye nokugqiba ukunciphisa i-short-circuit kwi-rotor surface.

2. Unyango lwe-insulation kwindawo yangaphakathi ye-rotor slot.

3. Ukunciphisa i-harmonics ngokuphucula i-stator winding design.

4. Ukuphucula uyilo lokulungelelaniswa kwe-rotor slot kunye nokunciphisa i-harmonics, ukwandisa i-stator kunye ne-rotor cogging, ukuyila i-rotor slot shape njengeendawo zokubeka ezikhethiweyo, kwaye usebenzise i-series-connected sinusoidal windings, i-winding edibeneyo kunye ne-winding-mgama emfutshane ukunciphisa kakhulu i-harmonics. ; Ukusebenzisa udaka lwemagnethi eslotyolweyo okanye i-magnetic slot wedge ukubuyisela i-wedge yesiqhelo yokugquma indawo kunye nokuzalisa i-slot ye-motor stator core ngodaka lwe-magnetic slot yindlela esebenzayo yokunciphisa ilahleko eyongezelelweyo elahlekileyo.

5 ilahleko yokungqubana komoya

Ilahleko yokungqubana komoya ibalelwa malunga ne-25% yelahleko iyonke yemoto, ekufuneka inikwe ingqwalasela efanelekileyo.Ilahleko yefriction ibangelwa ikakhulu ziibheringi kunye netywina, ezinokuncitshiswa ngala manyathelo alandelayo:

1. Ukunciphisa ubungakanani be-shaft, kodwa ukuhlangabezana neemfuno ze-torque yokuphuma kunye ne-rotor dynamics.

2. Sebenzisa iibheringi eziphezulu.

3. Sebenzisa isixokelelwano sokuthambisa esisebenzayo kunye nesithambiso.

4. Yamkela iteknoloji yokutywina ephezulu.
