Kugwiritsa Ntchito Permanent Magnet Synchronous Motor mu Elevator Development

Chitetezo ndi kudalirika pakukula ndi kugwiritsa ntchito ma elevator okhazikika a maginito synchronous motor.

Ma motors okhazikika a maginito a synchronous adapangidwa ndikugwiritsidwa ntchito pakupanga ndi kupanga ma elevator, zomwe zimathandizira kwambiri chitetezo ndi kudalirika kwamakina oyendera ma elevator. Makina oyendetsa akalephera kapena zolakwika zina zimapangitsa kuti elevator isunthike komanso kuthamanga mwachangu, imakhala ndi ntchito yoteteza chitetezo, yomwe imakwaniritsa zofunikira zaukadaulo wadziko langa GB7588-2003 (Mafotokozedwe a Chitetezo Pakupanga ndi Kuyika kwa Elevator) 9.10 "Elevator Upward Overspeed Protection Chipangizo". Mu chikepe chogwiritsira ntchito maginito okhazikika a synchronous traction motor, TV ikasiya kugwira ntchito, mafunde a galimotoyo amakhala ozungulira (kapena osakanikirana).

Chitetezo ndi kudalirika pakukula ndi kugwiritsa ntchito ma elevator okhazikika a maginito synchronous motor.

Maginito okhazikika a synchronous motor adapangidwa ndikugwiritsidwa ntchito pakupanga ndi kupanga ma elevator, zomwe zimathandizira kwambiri chitetezo ndi kudalirika kwa ma elevator traction system. Makina oyendetsa akalephera kapena zolakwika zina zimapangitsa kuti elevator isunthike komanso kuthamanga mwachangu, imakhala ndi ntchito yoteteza chitetezo, yomwe imakwaniritsa zofunikira zaukadaulo wadziko langa GB7588-2003 (Mafotokozedwe a Chitetezo Pakupanga ndi Kuyika kwa Elevator) 9.10 "Elevator Upward Overspeed Protection Chipangizo". Mu chikepe chogwiritsira ntchito maginito okhazikika a synchronous traction motor, TV ikasiya kugwira ntchito, mafunde amagetsi a galimotoyo amakhala ozungulira pang'ono (kapena amafupikitsidwa pambuyo polumikizana ndi chopinga chosinthika). Pamene vuto la overspeed (kaya likukwera kapena kugwa), makina owongolera amazindikira chizindikiro chothamanga, nthawi yomweyo amadula gawo lamagetsi la wowongolera, ndikufupikitsa mafunde amagetsi agalimoto (kapena chowongolera chosinthika). Panthawiyi, mafunde okhazikika amadula mphamvu ya maginito yomwe imapangidwa ndi maginito okhazikika, ndipo imapangitsa mphamvu ya electromotive, yomwe imapanga panopa mumayendedwe otsekedwa ndi zida zotsekedwa, ndikupanga torque pansi pa mphamvu ya maginito, kuyesa kuyendetsa. mapindikidwe a zida kuti azizungulira pamodzi ndi maginito pole. Pa nthawi yomweyo, makokedwe anachita makokedwe amachita pa mizati ozungulira, kuyesera kuletsa rotor pamodzi ndi stator armature mafunde, umene ndi mtundu wa braking makokedwe. Njirayi ndi yofanana ndi kuthamanga kwamphamvu kwa ma motors a DC, kuti mukwaniritse zoletsa kugwa ndi kuthawa (makokedwe a braking amatha kusinthidwa ndi kukana kuwongolera liwiro lothamanga). Kuyanjana kwa maginito okhazikika ndi kutsekedwa kwa zida zotsekedwa kumapanga chitetezo chopanda kukhudzana ndi njira ziwiri zodzitsekera pagalimoto, zomwe zimawonjezera chitetezo ndi kudalirika kwa chikepe, makamaka kumachepetsa mphero yachitetezo chazitsulo zosiyanasiyana zothamanga kwambiri. Malamba owonongeka pa liwiro lalikulu kuopsa kwa chitetezo.
