Txawm hais tias txoj hauv kev ua haujlwm ntawm AC servo lub cev muaj zog zoo ib yam li kev sib cais-theem ib-theem asynchronous lub cev muaj zog, lub rotor tsis kam ntawm lub qub yog ntau dua li ntawm tom kawg, yog li servo lub cev muaj peb yam tseem ceeb piv nrog ib lub tshuab asynchronous. lub cev muaj zog:
1. Lub zog pib yog loj
Due to the large resistance of the rotor, there is a significant difference compared with the torque characteristic curve of ordinary asynchronous motors. It makes the critical slip rate S0>1, uas tsis tsuas yog coj tus yam ntxwv torque (tus yam ntxwv ntawm cov tshuab) los ze zog rau linearity, tab sis kuj muaj lub zog pib loj. Yog li ntawd, thaum lub stator muaj ib tug tswj voltage, lub rotor tig tam sim ntawd, uas yog, nws muaj cov yam ntxwv ntawm ceev pib thiab siab rhiab heev.
2. Ntau yam kev ua haujlwm
3. Tsis muaj qhov tshwm sim tig
Nyob rau hauv ib txwm servo lub cev muaj zog, ntev npaum li qhov kev tswj qhov hluav taws xob poob, lub cev muaj zog yuav nres tam sim ntawd. Thaum lub servo lub cev muaj zog poob qhov kev tswj qhov hluav taws xob, nws yog nyob rau hauv ib-theem kev ua hauj lwm lub xeev, vim lub loj tsis kam ntawm lub rotor, ob tug torque yam ntxwv (T1-S1, T2-S2 nkhaus) thiab cov yam ntxwv torque tshwm sim (TS nkhaus) tsim los ntawm qhov kev txiav txim ntawm lub rotating magnetic teb rotating nyob rau hauv ob opposite lus qhia nyob rau hauv lub stator thiab lub rotor
Lub zog tso zis ntawm AC servo lub cev muaj zog feem ntau yog 0.1-100W. Thaum lub zog zaus yog 50Hz, qhov hluav taws xob yog 36V, 110V, 220, 380V, thiab thaum lub zog zaus yog 400Hz, qhov voltage yog 20V, 26V, 36V, 115V, thiab lwm yam.
AC servo lub cev muaj zog ua haujlwm zoo thiab muaj suab nrov tsawg. Txawm li cas los xij, cov yam ntxwv ntawm kev tswj tsis yog linear, thiab vim qhov loj rotor tsis kam, poob loj, thiab kev ua haujlwm qis, nws yog qhov loj hauv ntim thiab hnyav hauv qhov hnyav piv nrog DC servo motors ntawm tib lub peev xwm, yog li nws tsuas yog tsim rau qis- fais fab tswj systems ntawm 0 5-100W.
