Peranan sikat karbon ing motor bor impact

2023-01-29

Peranan sikat karbon bor impact yaiku ngirim arus eksitasi sing digawe dening generator eksitasi menyang kumparan rotor. Ing asas saka impact ngebur listrik iku sawise ing medan magnet ngethok kabel, arus digawe ing kabel. Generator nggunakake metode puteran medan magnet kanggo motong kabel. Sing muter medan magnet yaiku rotor, lan kabel sing dipotong yaiku stator. Supaya kanggo rotor kanggo generate kolom Magnetik, saiki eksitasi kudu input menyang kumparan rotor, lan rerumput karbon muter peran iki.

 

Nyatane, "sikat" ing kene nuduhake kanggo sikat karbon. Latihan impact umume nggunakake motor DC. Latihan impact disikat nggunakake motor disapu resik, kang kudu commutated liwat sikat. Karbon sikat wis commutated dening sensor Hall lan mimpin dening pembalap kanggo muter.

 

Dibandhingake karo latihan impact brushless, latihan impact disapu resik utamané duwe kaluwihan lan cacat ing ngisor iki:

 

Advantages: The brushed impact drill starts quickly, brakes timely, smooth speed regulation, simple control, simple structure, cheap price, and it has a large starting current, large torque (rotation force) at low speed, and can carry a heavy load.

 

Cacat: Amarga gesekan antarane rerumput karbon lan komutator, pengeboran impact karo sikat rawan kanggo percikan api, panas, gangguan, gangguan elektromagnetik menyang lingkungan njaba, lan efisiensi kurang lan urip cendhak; sikat karbon iku consumables, sawise periode wektu, iku bakal diganti, kang troublesome.
