Kev nyab xeeb thiab kev ntseeg siab hauv kev txhim kho thiab kev siv cov hlau nplaum ruaj khov synchronous lub cev muaj zog elevator.
Cov hlau nplaum tas mus li synchronous motors tau tsim thiab siv hauv of elevator tsim thiab tsim khoom, uas ua rau muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub tshuab nqa nqa. Thaum lub nres ntawm lub tshuab traction tsis ua haujlwm lossis lwm yam ua rau lub elevator plam thiab txawm tias khiav nrawm, nws muaj kev tiv thaiv kev nyab xeeb, uas ua tau raws li cov kev cai ntawm kuv lub teb chaws tus txheej txheem GB7588-2003 (Kev Nyab Xeeb Specification rau of elevator Manufacturing thiab Installation) 9.10 "Elevator Upward Overspeed Protection Device". Nyob rau hauv lub elevator siv ib tug tas mus li hlau nplaum synchronous traction motor, thaum lub TV tsis ua hauj lwm, lub cev muaj zog armature winding yog luv luv (los yog serialized).

Cov hlau nplaum ruaj khov synchronous lub cev muaj zog tau tsim thiab siv hauv of elevator tsim thiab tsim khoom, uas txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm elevator traction system. Thaum lub nres ntawm lub tshuab traction tsis ua haujlwm lossis lwm yam ua rau lub elevator plam thiab txawm tias khiav nrawm, nws muaj kev tiv thaiv kev nyab xeeb, uas ua tau raws li cov kev cai ntawm kuv lub teb chaws tus txheej txheem GB7588-2003 (Kev Nyab Xeeb Specification rau of elevator Manufacturing thiab Installation) 9.10 "Elevator Upward Overspeed Protection Device". Nyob rau hauv lub elevator siv ib tug tas mus li hlau nplaum synchronous traction lub cev muaj zog, thaum lub TV tsis ua hauj lwm, lub cev muaj zog armature winding yog luv luv Circuit Court (los yog luv luv-circuited tom qab ib tug adjustable resistor yog kev cob cog rua nyob rau hauv series). Thaum muaj overspeed (txawm yog nce los yog poob) txhaum tshwm sim, lub kaw lus tswj xyuas lub teeb liab overspeed, tam sim ntawd txiav tawm lub hwj chim mov Circuit Court ntawm tus maub los, thiab luv luv-circuits lub cev muaj zog armature winding (los yog adjustable resistor nyob rau hauv series). Nyob rau lub sijhawm no, lub tshuab hluav taws xob zoo li qub txiav tawm cov hlau nplaum uas tsim los ntawm cov hlau nplaum ruaj khov, thiab ua rau lub zog hluav taws xob, uas ua rau lub zog tam sim no nyob rau hauv lub kaw armature winding Circuit Court, thiab generates torque nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb, sim tsav. lub armature winding los tig ua ke nrog tus ncej hlau nplaum. Nyob rau tib lub sijhawm, torque cov tshuaj tiv thaiv torque ua rau ntawm tus ncej rotor, sim nres lub rotor ua ke nrog stator armature winding, uas yog hom braking torque. Cov txheej txheem no zoo ib yam li lub zog ntawm DC lub cev muaj zog, kom ua tiav kev tiv thaiv lub caij nplooj zeeg thiab kev khiav tawm (lub braking torque tuaj yeem hloov kho los ntawm kev tiv thaiv kev khiav ceev). Kev sib cuam tshuam ntawm cov hlau nplaum ruaj khov thiab kaw armature winding ua rau tsis sib cuag ob txoj kev tiv thaiv tus kheej kaw ntawm qhov chaw nres tsheb, uas ua rau kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub elevator, tshwj xeeb tshaj yog txo qhov kev nyab xeeb ntawm ntau lub elevator high-speed. Kev puas tsuaj ntawm txoj siv sia ntawm kev kub ceev kev ruaj ntseg txaus ntshai.
