Ukusetyenziswa kwe-Permanent Magnet Synchronous Motor kuPhuhliso lwe-Elevator

Ukhuseleko kunye nokuthembeka kuphuhliso kunye nokusetyenziswa kwemagnethi esisigxina ye-synchronous motor elevators.

Iimotor ezisisigxina zemagnethi ezilungelelanisiweyo ziye zaphuhliswa kwaye zasetyenziswa kuyilo lwe-elevator kunye nemveliso, ephucula kakhulu ukhuseleko kunye nokuthembeka kweenkqubo zokutsalwa kwe-elevator.Xa isiqhoboshi somatshini wokutsala usilela okanye ezinye iziphene zibangela ukuba ilifti ityibilike kwaye ibaleke ngokukhawuleza, inomsebenzi wokhuseleko wokhuseleko, ohlangabezana neemfuno zomgangatho wobugcisa belizwe lam le-GB7588-2003 (Inkcazo yoKhuseleko lwe-Elevator Manufacturing and Installation) 9.10 “Isixhobo soKhuseleko seLifti esiPhakamileyo”.Kwi-elevator esebenzisa imagnethi esisigxina yokutsala i-motor, xa i-TV iyeka ukusebenza, i-motor's armature winding i-short-circuited (okanye i-serialized).

Ukhuseleko kunye nokuthembeka kuphuhliso kunye nokusetyenziswa kwemagnethi esisigxina ye-synchronous motor elevators.

I-magnetic esisigxina ye-synchronous motor iye yaphuhliswa kwaye yasetyenziswa kuyilo lwe-elevator kunye nemveliso, ephucula kakhulu ukhuseleko kunye nokuthembeka kwenkqubo ye-elevator traction.Xa isiqhoboshi somatshini wokutsala usilela okanye ezinye iziphene zibangela ukuba ilifti ityibilike kwaye ibaleke ngokukhawuleza, inomsebenzi wokhuseleko wokhuseleko, ohlangabezana neemfuno zomgangatho wobugcisa belizwe lam GB7588-2003 (Ucaciso loKhuseleko lwe-Elevator Manufacturing and Installation) 9.10 “Isixhobo soKhuseleko seLifti esiPhakamileyo”.Kwi-elevator esebenzisa imagnethi esisigxina ye-synchronous traction motor, xa i-TV iyeka ukusebenza, i-motor armature winding i-short-circuited (okanye i-short-circuited emva kokuba i-resistor ehlengahlengiswayo idityaniswe kuthotho).Xa i-overspeed (nokuba inyuka okanye iwa) iphosakele, inkqubo yokulawula ibona umqondiso we-overspeed, ngokukhawuleza inqumle i-circuit yonikezelo lwamandla yomlawuli, kunye neesekethe ezimfutshane i-armature winding ye-motor (okanye i-resistor adjustable in series).Ngeli xesha, i-static winding inqumla i-magnetic field eveliswa yimagnethi ejikelezayo ejikelezayo, kwaye yenza amandla e-electromotive, avelise i-current kwi-armature winding circuit, kwaye ivelise i-torque phantsi kwesenzo somhlaba wemagnethi, ezama ukuqhuba. i-armature winding ukujikeleza kunye nepoleni yemagnethi.Ngelo xesha, i-torque reaction torque isebenza kwiipali ze-rotor, izama ukumisa i-rotor kunye ne-stator armature winding, eluhlobo oluthile lwe-torque yokuqhawula.Le nkqubo ifana ne-dynamic braking ye-DC motors, ukwenzela ukuba kuphunyezwe ukuchasana nokuwa kunye nokuthintela ukukhutshwa (i-torque ye-braking inokulungiswa ngokumelana nokulawula isantya sokuhamba).Ukusebenzisana kwemagnethi esisigxina kunye ne-armature winding evaliweyo ivelisa ukhuseleko olunganxibelelwano lweendlela ezimbini zokuzivala kwindawo yokupaka, nto leyo eyandisa kakhulu ukhuseleko kunye nokuthembeka kwe-elevator, ngokukodwa kunciphisa ukhuseleko lwe-wedge ye-elevators ezahlukeneyo zesantya esiphezulu.Iibhanti ezonakeleyo kwisantya esiphezulu imingcipheko yokhuseleko.
