Lub Dawv DC tsav (BLDC) tsuas yog cov stator, lub rotor thiab txoj haujlwm sensor. Lub stator feem ntau yog ua los ntawm chev windings, thiab rotor yog lub hlau nplaum tas mus li. Lub stator tuaj yeem ua rau hauv ib qho peb-theem symmetrical hnub qub kev twb kev txuas, zoo ib yam li peb-theem asynchron tsav. Lub rotor yog txuas nrog hlau nplaum hlau nplaum ruaj khov, thiab txoj hauj lwm sensor yog siv los tshawb xyuas qhov chaw ntawm lub rotor.
Cov Qauv Qhia Ntawv
Stator: Lub stator muaj coil windings, feem ntau yog ua rau hauv ib qho peb-theem symmetrical hnub qub kev twb kev sib txuas. Lub stator winding tuaj yeem yog trapezoidal lossis sinusoidal, nyob ntawm daim ntawv thov yuav tsum tau ua.
Rotor: lub rotor yog ua los ntawm cov hlau nplaum tas mus li, feem ntau tsis tshua muaj cov hlau coron (SMCO), thiab lwm yam ntawm cov lej rotor (SMCO)
Txoj Haujlwm Sensor: Vim tias tsis muaj cov txhuam hniav hauv qhov tsis txhuam DC tsis muaj zog, lub commutation yog tswj hluav taws xob hauv tshuab hluav taws xob. Txoj hauj lwm sensor (feem ntau yog ib qho sensor) yog siv los tshawb xyuas qhov chaw ntawm lub rotor thiab hloov cov ncauj lus hauv lub cev mus rau qhov ua kom sib luag ntawm lub stator windings.
