High-speed motor test cov ntsiab lus thiab cov kev daws teeb meem
High-speed kuj sib txawv deb zaus yog hais txog kev ceev tshaj 10000r / min, feem ntau ntawm kaum txhiab tus revolutions los yog ntau pua txhiab tus revolutions. Nws muaj sab nrauv daim ntawv thov nyob rau hauv hluav taws xob cov tsheb thiab muab faib tshuab. Nyob rau hauv cov ntaub ntawv ntawm kev kub ceev thiab ultra high speed lub lag luam, tus cwj pwm khiav ntawm lub cev muaj peev xwm sib txawv los ntawm cov ntawm cov pa tsheb. Nws tseem ceeb heev kom kuaj lub siab ceev qev.
High-speed kuj sib txawv deb zaus yog hais txog kev ceev tshaj 10000r / min, feem ntau ntawm kaum txhiab tus revolutions los yog ntau pua txhiab tus revolutions. Lub cav tawm tswv yim siv qhov dav npaum li cas yog 1000Hz los yog siab dua, thiab tus naj npawb ntawm ncej yog 2 theem. High-speed motors muaj qhov tshwj xeeb zoo xws li kev kub ceev, tus me me loj, siab zog ceev, thiab kev ua haujlwm siab. Lawv siv ntau daim ntawv xws li centrifugal compressors, lub zog cia flywheels, textiles, high-speed grinders, etc. nyob rau hauv cov tsheb thiab kev faib tawm. Lub kaw lus hluav taws xob tau muaj kev pom dav dav. Nyob rau hauv cov ntaub ntawv ntawm kev kub ceev thiab ultra high speed lub lag luam, tus cwj pwm khiav ntawm lub cev muaj peev xwm sib txawv los ntawm cov ntawm cov pa tsheb. Nws tseem ceeb heev kom kuaj lub siab ceev qev.
High-speed motor test cov ntsiab lus
1, kev kub ceev kev sib tw ua kom muaj zog
High-speed motors muaj siab zog ntom nti, tab sis qhov poob ntawm ib chav tsev ntim kuj loj heev, tshwj xeeb tshaj yog cov rotor cua hnav thiab eddy tam sim no poob yog kaum ob ntawm lub sij hawm uas ntawm cov kev taw qhia dav dav. Kev ua haujlwm ntawm kev ua haujlwm siab (high-speed motor) yog tau los ntawm qhov ntsuas kev ntsuas lub zog (xws li qhov hluav taws xob, tam sim no, lub zog, qhov muaj zog, lwm yam), kev ntsuas tawm (ceev, lub zog, lub zog, lwm yam) qhov zoo li. Cov kev ntsuas siab ntawm kev ua haujlwm siab rau kev siv zog yog siv los txheeb xyuas qhov kev poob kev cuam tshuam nrog kev kub ceev. Nws yog tus yuam sij rau cov qauv tsim ntawm cov tshuab hluav taws xob, kev txhim kho cov yam ntxwv, kev kho cua sov, thiab txo cov kev poob qis.
2. Kev kub ceev lub cev muaj zog fais fab kev tswj xyuas
High-speed motors feem ntau yog siv tau los ntawm cov neeg siv khoom sib hloov thiab muaj kev nkag siab txog cov qauv siv thiab kev sib haum xeeb ntawm lub hwj chim cev. Qhov kev ntsuas hluav taws xob tau tawm los ntawm qhov inverter yog PWM nthwv dej. Ntxiv nrog rau txoj kev siv zog, nws kuj muaj coob tus high-order harmonics ntawm integer ntau ntau tus neeg mob lub cev, uas yuav coj cov high-zaus ntxiv poob mus rau high-speed lub cev. Yog li ntawd, kev khiav hauj lwm txheej xwm thiab kev cia siab ntawm kev xyuas ntawm lub zog fais fab Nws Nws tseem ceeb heev.
