Piv nrog AC induction lub cev muaj zog, brushless DC lub cev muaj qhov zoo hauv qab no:

1. rotor txais cov hlau nplaum uas tsis muaj qhov zoo siab tam sim no. Tib lub zog hluav taws xob tuaj yeem ua tiav cov tshuab hluav taws xob ntau dua.

2. lub rotor tsis muaj tooj liab thiab hlau poob, thiab qhov kub thiab txias yog txawm me dua.

3. lub sijhawm pib thiab thaiv lub sijhawm yog qhov loj, uas muaj txiaj ntsig zoo rau lub zog tam sim no xav tau rau lub valve qhib thiab kaw.

4. cov zis torque ntawm lub cev muaj zog yog ncaj qha proportional rau qhov ua hauj lwm voltage thiab tam sim no. Lub torque detection Circuit Court yog yooj yim thiab txhim khu kev qha.

5. los ntawm kev kho qhov nruab nrab tus nqi ntawm cov khoom siv hluav taws xob los ntawm PWM, lub cev muaj zog tuaj yeem kho tau zoo. Kev tswj ceev ceev thiab tsav lub zog hluav taws xob yog qhov yooj yim thiab txhim khu kev qha, thiab tus nqi qis.

6. los ntawm kev txo cov khoom siv hluav taws xob thiab pib lub cev muaj zog los ntawm PWM, qhov pib tam sim no tuaj yeem txo tau zoo.

7. lub cev muaj zog fais fab mov yog PWM modulated DC voltage. Piv nrog rau sine yoj AC fais fab mov ntawm AC hloov pauv zaus lub cev muaj zog, nws txoj kev tswj ceev thiab tsav Circuit Court tsim hluav taws xob tsawg dua thiab muaj kuab paug tsawg dua rau hauv daim phiaj.

8. siv lub voj kaw nrawm tswj Circuit Court, lub cev muaj zog tuaj yeem hloov pauv thaum thauj khoom torque hloov.
