Taw qhia rau Brushless DC Motors

Brushless DC lub cev muaj zog yog ib yam khoom siv mechatronics uas tsim los ntawm lub cev lub cev thiab tsav tsheb. Brushless lub cev muaj zog yog hais txog lub cev muaj zog uas tsis muaj txhuam thiab commutators (lossis cov nplhaib sib sau), tseem hu ua commutator free motor. Raws li thaum ntxov xyoo pua 19th, thaum hluav taws xob motors tau yug los, lub tswv yim daim ntawv ntawm hluav taws xob motors yog brushless, namely AC squirrel tawb asynchronous motors, uas tau dav siv. Txawm li cas los xij, asynchronous motors muaj ntau yam tsis xws luag, uas ua rau qeeb qeeb ntawm kev siv tshuab. Nyob rau hauv nruab nrab -19th caug xyoo, transistors tau yug los, ua rau siv cov transistor commutation circuits los hloov txhuam thiab commutators hauv brushless DC motors. Hom tshiab ntawm brushless lub cev muaj zog yog hu ua hluav taws xob commutated DC lub cev muaj zog, uas kov yeej qhov tsis txaus ntawm thawj tiam ntawm brushless motors.
