20V Lithium bhatiri isina cord drill

Musiyano mukuru pakati pelithium drill mota uye brushless mota uri mukuvaka nekushanda kwavo:

Brushed Motor: Traditional lithium drills anowanzo shandisa brushed motors. Aya mamotor ane kabhoni mabhurashi anoendesa simba kune inofambisa, iyo inozotenderedza mota yacho. Sezvo mota ichitenderera, mabhurashi anoita kusangana kwemuviri neanoenda, achigadzira kupokana uye kugadzira kupisa. Uku kupokana uye kupfeka pamabhurashi uye commutator kunogona kutungamira mukudzikiswa kwekuita uye hupenyu nekufamba kwenguva.

Brushless Motor: Brushless motors, kune rumwe rutivi, usashandise mabhurashi kana commutator pakuunza magetsi. Pane kudaro, vanovimba nemagetsi controllers kuti vanyatso kudzora kuyerera kwemagetsi kune mota windings. Iyi dhizaini inobvisa kudiwa kwemabhurashi, kuderedza friction uye kupfeka. Nekuda kweizvozvo, mabhurashi motors anowanzo kuve nehunyanzvi hwepamusoro, hurefu hwehupenyu, uye akanyarara kana achienzaniswa neakabhurwa mota. Ivo zvakare vanowanzo buritsa simba rakawanda rehukuru hwakafanana uye huremu, zvichiita kuti vawedzere kufarirwa mumaturusi emagetsi senge madhiri.

Muchidimbu, nepo mhando mbiri dzemotor dzichigona kugonesa lithium drill, brushless mota dzinopa mabhenefiti mukubudirira, hupenyu, uye kuita. Nekudaro, ivo vanogona kuuya nemutengo wepamusoro wekutanga uchienzaniswa nemadrill ane brushed motors.

Lithium drill bhurashi mota kazhinji inoreva rudzi rwemota inoshandiswa mumidziyo yemagetsi senge madhiri uye zvinonamirwa nebhurashi. Lithium inoreva rudzi rwebhatiri rinogonesa chibooreso, nepo mota pachayo inogona kunge iri brashi kana brushless DC mota.

Mabhurashi mota ane kabhoni mabhurashi anoendesa magetsi kune inotenderera armature, nepo brushless mota dzinoshandisa emagetsi controller kuendesa simba kumhepo. Brushless motors inowanzova inoshanda uye yakasimba pane yakabhurwa mota, asi iwowo anowanzo kudhura.

Lithium-ion mabhatiri anowanzo shandiswa mumidziyo yemagetsi nekuda kwekuwanda kwesimba uye hunhu hwekuchajika, ichipa nguva yakareba yekumhanya kana ichienzaniswa nedzimwe mhando dzebhatiri. Kana yakasanganiswa nebhurashi mota, lithium-ion-powered drills inogona kupa kushanda kwepamusoro uye hupenyu hurefu hwekushandisa.
