Ukusetyenziswa kwe-Permanent Magnet Synchronous Motor kuPhuhliso lwe-Elevator

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

Iimotor ezisisigxina zemagnethi ezihambelanayo 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 esiPhezulu 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).

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 le-GB7588-2003 (Inkcazo yoKhuseleko lwe-Elevator Manufacturing and Installation) 9.10 “Isixhobo soKhuseleko seLifti esiPhezulu 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 iphakama 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 ehlengahlengiswayo kwi-series). Ngeli xesha, i-static winding inqumla i-magnetic field eveliswa yimagnethi ejikelezayo ejikelezayo, kwaye ibangela amandla ombane, ovelisa i-current kwi-armature winding circuit, kwaye ivelise i-torque phantsi kwesenzo semagnethi, ukuzama 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 yokunyathela. Le nkqubo ifana ne-dynamic braking ye-DC motors, ukwenzela ukuba kuphunyezwe ukuchasana nokuwa kunye nokuthintela ukukhutshwa (i-torque ye-braking inokulungiswa ngokuxhathisa ukulawula isantya sokuhamba). Ukusebenzisana kwemagnethi esisigxina kunye ne-armature winding evaliweyo ivelisa ukhuseleko lweendlela ezimbini zokuzivala zokuzivala kwindawo yokupaka, okwandisa kakhulu ukhuseleko kunye nokuthembeka kwe-elevator, ngokukodwa kunciphisa ukhuseleko lwe-wedge ye-elevators ezahlukeneyo zesantya esiphezulu. Iibhanti ezonakeleyo ngesantya esiphezulu imingcipheko yokhuseleko.
