Thaum lub sij hawm rotating dheev nrawm los yog decelerates - los yog txawm tias muaj ib lub jarring, jerky motion - nws tsis tsuas cuam tshuam lub atherosclerosis ntawm qhov kev ua tau zoo tab sis kuj tuaj yeem ua rau cov khoom puas. Lub hauv paus ua rau ntawm qhov tshwm sim no feem ntau yog nyob rau hauv cov teeb meem ntsig txog kev xa hluav taws xob thiab kev hloov pauv ntawm cov khoom thauj.
Rotating theem feem ntau yog tsav los ntawm kev sib txawv - zaus motors; lawv cov kev ua haujlwm ruaj khov yog nyob ntawm kev faib khoom, sib txawv - zaus tsav (VFD) tsis, thiab cov qauv siv tshuab. Yog hais tias theem scenery los yog cov neeg ua yeeb yam tau tsom rau ntawm ib sab, tsim kom muaj qhov tsis sib xws ntawm cov khoom xa tawm, lub cev muaj zog lub zog yuav hloov pauv ntawm - alternating ntawm siab thiab qis - yog li ua rau variations nyob rau hauv rotational ceev. Tsis tas li ntawd, yog tias lub sijhawm acceleration thiab deceleration ramp lub sij hawm nyob rau hauv lub VFD yog configured tsis raug, lub cev muaj zog yuav pom abrupt thiab jarring ceev hloov thaum lub sij hawm ua hauj lwm.
Tsis tas li ntawd, hnav thiab tsim kua muag nyob rau hauv lub tshuab tshuab - xws li cov iav xoob lossis tsis txaus siv txoj siv tawv - tuaj yeem cuam tshuam qhov ruaj khov ntawm kev xa hluav taws xob. Optimizing qhov ruaj khov ntawm qhov chaw sib hloov ntawm peb qhov tseem ceeb: kev sib npaug ntawm qhov sib npaug, VFD calibration, thiab kev tswj lub zog hloov pauv. Kev faib khoom thauj khoom yuav tsum tau khaws cia tsis tu ncua; Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau theem featuring scenery uas nws kim heev kev hloov, qhov twg counterweights yuav tsum tau ntxiv kom ua tau raws li qhov sib npaug.
Lub acceleration thiab deceleration curves nyob rau hauv lub VFD yuav tsum tau calibrated kom tsim nyog los tiv thaiv torque rhiab heev uas yuav adversely cuam tshuam rau rotational ceev. Ntau qhov kev hloov theem siab tshaj plaws tau nruab nrog kev hloov kho lub zog tswj lub tshuab uas saib xyuas cov kev hloov pauv hauv lub sijhawm tiag tiag -, hloov kho lub cev muaj zog cov zis kom ntseeg tau tias muaj kev sib hloov zoo dua.
