Kuunzwa kwemota yeDC isina brushless muzvishandiso zvemagetsi

Nekuvandudzika kwetekinoroji itsva yekudzora mabhatiri nemagetsi, mari yekugadzira nekugadzira mota dzeDC dzisina mabhurashi yadzikiswa zvakanyanya, uye zvishandiso zvinochajwa zviri nyore zvinoda mota dzeDC dzisina mabhurashi zvave kufarirwa uye zvichishandiswa zvakanyanya. Inoshandiswa zvakanyanya mumaindasitiri ekugadzira, kugadzira nekugadzira, kunyanya nekukura kwehupfumi, kudiwa kwedzimba kuri kuramba kuchikwira, uye mwero wekukura kwegore negore wakakwira zvakanyanya kupfuura wemamwe maindasitiri.

2, mhando yekushandiswa kwemota yemagetsi inochajwazve

2.1 Mota yeDC yakakweshwa

Chimiro chemota yeDC isina mabhurashi chinosanganisira rotor (shaft, iron core, winding, commutator, bearing), stator (casing, magnet, end cap, nezvimwewo), carbon brush assembly, carbon brush arm nezvimwe zvikamu.

Nheyo yekushanda: Stator yemota yeDC yakakweshwa yakaiswa nedanda guru rakagadzika (magnet) nebhurashi, uye rotor yakaiswa ne armature winding uye commutator. Simba remagetsi remagetsi eDC rinopinda mu armature winding kuburikidza ne carbon brush uye commutator, zvichigadzira armature current. Simba remagineti rinogadzirwa ne armature current rinoshanda nesimba guru remagineti kugadzira electromagnetic torque, izvo zvinoita kuti mota itenderere uye ifambise mutoro.

Zvakashata: Nekuda kwekuvapo kwebhurashi rekabhoni necommutator, kuvimbika kwemota yebhurashi hakuna kunaka, kutadza kushanda zvakanaka, kusagadzikana kwemagetsi, hupenyu hupfupi, uye commutator spark zvinogadzira kupindirana kwemagetsi.

2.2 Mota yeDC isina bhurashi

Chimiro chemota yeDC isina brush chinosanganisira rotor yemota (shaft, iron core, magnet, bearing), stator (casing, iron core, winding, sensor, end cover, nezvimwewo) uye zvikamu zve controller.

Musimboti wekushanda: Mota yeDC isina brushless ine muviri wemota nemutyairi, chigadzirwa chemechatronics chakajairika. Musimboti wekushanda wakafanana newemota yebrush, asi commutator yechinyakare nekabhoni brush zvinotsiviwa neposition sensor necontrol line, uye direction yemagetsi inoshandurwa necontrol command inopihwa nesensor signal kuti iite commutation work, kuitira kuti ive nechokwadi chekuti electromagnetic torque ne steering yemota zvinogara zviripo uye kuti mota itenderere.

Kuongororwa kwemota yeDC isina brushless muzvishandiso zvemagetsi

3. Zvakanakira nezvakaipa zvekushandisa mota yeBLDC

3.1 Mabhenefiti emota yeBLDC:

3.1.1 Chimiro chiri nyore uye hunhu hwakavimbika:

Kanzura commutator, bhurashi rekabhoni, ruoko rwebhurashi nezvimwe zvikamu, hapana welding commutator, maitiro ekupedzisa.

3.1.2 Hupenyu hwebasa hurefu:

Kushandiswa kwezvikamu zvemagetsi kutsiva chimiro chekare checommutator, kubvisa mota nekuda kwebhurashi rekabhoni uye commutator commutator spark, kusakara kwemuchina nezvimwe zvinetso zvinokonzerwa nehupenyu hupfupi, hupenyu hwemotokari hunowedzerwa neakawanda.

3.1.3 Kushanda zvakanaka uye kwakanyarara:

Hapana bhurashi rekabhoni uye chimiro checommutator, dzivisa spark yecommutator uye kukakavadzana kwemakanika pakati pebhurashi rekabhoni necommutator, zvichikonzera ruzha, kupisa, kurasikirwa nesimba remota, uye kuderedza kushanda zvakanaka kwemota. Kushanda zvakanaka kwemota yeDC isina brush mu60~70%, uye kushanda zvakanaka kwemota yeDC isina brush kunogona kusvika 75~90%

3.1.4 Kugona kukuru kwekudzora nekudzora kumhanya:

Zvikamu zvemagetsi nemasensa akanyatsonaka zvinogona kudzora kumhanya kwekubuda, torque nenzvimbo yemota nemazvo, zvichiita kuti injini ive yakangwara uye ine mabasa akawanda.
