Kushanda musimboti we brushed electric drill

The HammerDhiraivha 28MMChimiro chikuru chebrashi yemagetsi drill ndiyo stator + rotor + mabhurashi, ayo anowana torque inotenderera kuburikidza neinotenderera magineti, nekudaro ichiburitsa kinetic simba.Iyo bhurashi uye commutator inogara ichisangana uye kupokana, uye inoita basa rekufambisa uye kutenderera panguva yekutenderera.

Iyo brushed yemagetsi drill inotora mechanical commutation, iyo magnetic pole haifambi, uye coil inotenderera.Kana chibooreso chemagetsi chiri kushanda, coil necommutator zvinotenderera, asi simbi yemagineti nekabhoni brashi hazvitenderere.Iyo inochinjika ikozvino kutungamira kwekoiri inoshandurwa neinverter uye bhurashi remagetsi rinotenderera nemagetsi drill.

Mukuita uku, iwo maviri emagetsi ekuisa mapeji ecoil anorongedzerwa mumhete, akapatsanurwa kubva kune mumwe nemumwe ne insulating zvinhu kuti agadzire humburumbira, iyo yakabatana kune yemagetsi drill shaft.Iyo magetsi inogadzirwa nezvinhu zviviri zvekabhoni.Mbiru diki (kabhoni mabhurashi), pasi pekuita kwekudzvanywa kwechirimo, dzvanya mapoinzi maviri pamusoro pepamusoro coil simba rekuisa mhete cylinder kubva panzvimbo mbiri dzakatarwa kuti upe simba coil.

Sezvo chibooreso chemagetsi chinotenderera, makoiri akasiyana kana mapango maviri ekoiri imwe chete anopihwa simba panguva dzakasiyana, kuitira kuti NS danda rekoiri rinogadzira magnetic field uye NS pole yepedyo inogara magineti stator ine yakakodzera kona musiyano., Gadzira simba rekusundira chibooreso chemagetsi kuti chitenderere.Kabhoni electrode inotsvedza pacoil terminal, sebhurashi riri pamusoro pechinhu, saka inonzi kabhoni "brush".

Iwo anonzi "akabudirira mabhurashi, kutadza zvakare mabhurashi."Nekuda kweiyo mutual sliding, iyo kabhoni mabhurashi anozokwizwa, zvichikonzera kurasikirwa.Iyo yekubatidza nekunze kwemabhurashi ekabhoni uye macoil terminals achachinjana, uye mazhenje emagetsi achaitika, kupwanya kwemagetsi kuchagadzirwa, uye michina yemagetsi ichakanganiswa.Uyezve, nekuda kwekuenderera mberi kutsvedza uye kukweshana, mabhurashi anozogara achipfeka uye kubvaruka zvakare iri honzeri yenguva pfupi-pfupi yebhurashi drill.

Kana bhurashi rikakuvadzwa, rinoda kugadziriswa, asi zvichanetsa here kurigadzirisa zvakare uyezve?Muchokwadi, hazvizodaro, asi hazvingave nani here kana paine chibooreso chemagetsi chisingade kushandura brashi?Iyi ndiyo brushless drill.

Kushanda musimboti webrushless electric drill

Brushless electric drill, sezvinoreva zita racho, chibooreso chemagetsi chisina bhurasho remagetsi.Iye zvino sezvo pasina bhurasho remagetsi, chibooreso chemagetsi chingaramba chichishanda sei?

Zvinoitika kuti chimiro chebrushless electric drill chakanyatsopesana neicho chebrashi yemagetsi drill:

Mubrushless electric drill, basa rekufambisa rinopedzwa nedunhu rekutonga mune controller (kazhinji Hall sensor + controller, yakawedzera tekinoroji ndeyemagnetic encoder).

Iyo brushed electric drill ine yakagadziriswa magnetic pole uye coil inotendeuka;brushless electric drill ine yakagadziriswa coil uye magnetic pole inotendeuka.Mune brushless electric drill, iyo Hall sensor inoshandiswa kuona nzvimbo yemagnetic pole yegineti yekusingaperi, uye zvino maererano nemafungiro aya, dunhu remagetsi rinoshandiswa kushandura nzira yezvino mucoil panguva yakakodzera. kuve nechokwadi chekuti simba remagineti munzira kwayo rinogadzirwa kutyaira dhiraivha yemagetsi.Bvisa kukanganisa kwebrashi yemagetsi drills.

Aya maseketi ndiwo anodzora mabhurashi emagetsi madhiri.Vanogona zvakare kuita mamwe mabasa asingakwanisi kuitwa nemagetsi ekudhiraivha, sekugadzirisa magetsi switch angle, braking electric drill, kugadzira dhiri remagetsi reverse, kukiya chibooreso chemagetsi, uye kushandisa brake siginecha kumisa simba reku drill yemagetsi. ..Iyo yemagetsi alarm lock yemotokari yebhatiri ikozvino inoshandisa zvizere mabasa aya.
