Brushless DC mota AC servo system iri kusimukira nekukurumidza nekuda kweiyo inertia diki, hombe yekubuda torque, kudzora kuri nyore uye yakanaka simba remhinduro.Iine tarisiro yakakura yekushandisa.Mumunda wekuita kwepamusoro uye yakakwira chaiyo servo drive, zvishoma nezvishoma inotsiva yechinyakare DC servo system.Nekudaro, iyo torque ripple ichiripo muBLDC, iyo isingakwanise kuwana yakawanda chinzvimbo chekutonga uye yepamusoro yekuita yekumhanyisa kutonga.Phase ikozvino kutenderera ndicho chimwe chezvikonzero zvikuru zve torque ripple.

Mune AC servo system ine isiri-yekufamba chikamu chezvino mhinduro, yakaderera-inomhanya inomhanya torque ripple inogona kudzorwa, asi haigone kudzorwa mumamiriro ekumhanya-mhanya, isiri-inotenderera chikamu chazvino haidzoreki.Naizvozvo, zvinodikanwa kuwana yakagadziridzwa commutation scheme kuti uwane zvirinani commutation torque performance.

Iyo inobudirira yekushandura mamiriro eiyo inverter mukugadzirisa maitiro inofanira kusarudzwa maererano nemitemo.

Mutemo 1: Tevera ikozvino rotor chinzvimbo, ndiko kuti, kudzima inoenderana switch inofanira kunyangarika, uye inoenderana switch inofanira kusimbiswa.

Mutemo wechipiri: pasi peRule 1, single and bipolar controls inogona kushandiswa.

Mutemo 3: bvumira kunonoka kwekuchinja kunoenderana kudzimwa.

Kukodzera uye kutadza kweiyo switch control strategy pasi pe commutation state inoongororwa neanotevera ma indexes:

1.torque pulsation inokonzerwa nekuchinja idiki sezvinobvira (kwete kushandura ikozvino pulsation sediki sezvinobvira).

2. kupfupisa nguva yekufambisa sezvinobvira.

NeETL, CE, ROHS, REACH certification, 60% yezvigadzirwa zveWonsmart zvinotumirwa kuNorth America, EU, Japan neKorea.Vatengi vanobva kunyika idzi vanogutsikana kwazvo nemhando yakagadzikana yeWonsmart, kukurumidza kutumira uye mutengo unonzwisisika.

Isu tinogashirawo ODM neOEM mapurojekiti uye akajairwa maitiro.

Isu tinokuvimbisa kuti unongoda kuisa odha, uye inoburitsa zvigadzirwa zvemhando yepamusoro.

Ndapota inzwa wakasununguka kutibata nesu.
