Cov hlau nplaum ruaj khov synchronous servo lub cev muaj zog yog tsim los ntawm lub qhov txhab synchronous lub cev muaj zog. Nws hloov lub tshuab hluav taws xob ua hluav taws xob nrog cov hlau nplaum tas mus li, Servo Lub Cev Muaj Zog dhau los tshem tawm cov kauj kev sib tw, lub nplhaib ntiv nplhaib thiab txhuam. Tus stator tam sim no yog qhov zoo ib yam li cov xov hluav taws xob synchronous tsav. Cov tswv yim yog cov hluav taws xob sinusoidal hloov chaw tam sim no, yog li nws hu ua AC haujlwm ruaj nrees hlau nplaum synchronous servo lub cev muaj zog.
Cov hlau nplaum ruaj khov synchronous servo lub cev muaj zog yog li ntawm stator thiab rotor. Tus stator mas suav nrog qhov nruab nrab ntawm cov tub ntxhais ua haujlwm thiab peb-theem (lossis ntau theem) ob sab uas sib zog. Cov windings yog ntim rau hauv cov kab ntawm cov tub ntxhais; lub rotor feem ntau yog tsim los ntawm cov hlau nplaum ruaj khov, Servo Tsav lub cev muaj zog yokes thiab tig ua haujlwm. Cov hlau nplaum ruaj khov yog txuas rau ntawm lub cuab khuam sib nqus, thiab cov quab hlau sib nqus yog cylindrical thiab lub tes tsho ntawm txoj haujlwm tig; thaum txoj kab uas hla ntawm lub rotor tseem me me, cov hlau nplaum tas mus li tuaj yeem txuas ncaj qha mus rau kev sib nqus daim hlau hlau.
Lub rotor yog coaxially txuas nrog txoj hauj lwm thiab nrawm ntsuas qhov txhawm rau txhawm rau txheeb xyuas qhov chaw sib piv ntawm rotor sib nqus ncej txheeb ze rau stator winding thiab rotor ceev. Thaum lub ntu peb-theem tam sim no hla dhau lub armature winding ntawm lub hlau nplaum ruaj khov synchronous servo lub cev muaj zog, tus stator tsim cov teb tig sib nqus uas txav ntawm lub ceev synchronous. Hauv lub xeev khov kho, Servo Tsav lub rotor ceev yog ib txwm synchronous ceev ntawm lub suab sib nqus
