Brushless DC mota AC servo system iri kukura nekukurumidza nekuda kwayo diki inertia, hombe kuburitsa torque, yakapusa kutonga uye yakanaka simba mhinduro. Iyo ine yakafara yekushandisa tarisiro. Mumunda weakakwira kuita uye yakakwira chaiyo servo dhiraivhu, zvishoma nezvishoma inotsiva yetsika DC servo system. Nekudaro, iyo torque ripple ichiripo muBLDC, iyo isingakwanise kuwana yakawanda nzvimbo chinzvimbo uye yepamusoro kuita nekumhanyisa kutonga. Chikamu chekuchinja ikozvino ndicho chimwe chezvikonzero zvikuru zvekuputika kwetambo.

Mune AC servo system ine isiri-inochinja chikamu chazvino mhinduro, yakaderera-kumhanya inochinja torque ripple inogona kudzorwa, asi haigone kudzorwa mune yakakwira-kukurumidza mamiriro, isiri-inochinja chikamu chazvino isingadzoreki. Naizvozvo, zvinodikanwa kuti uwane yakagadziriswa commutation scheme kuti uwane zvirinani commutation torque kuita.

Iyo inoshanda yekuchinja mamiriro eiyo inverter mune yekuchinja maitiro inofanirwa kusarudzwa zvinoenderana nemitemo.

Mutemo 1: Tevedza yazvino rotor chinzvimbo, ndiko kuti, bvisa inoenderana switch inofanira kunyangarika, uye inoenderana switch inofanira kusimbiswa.

Mutemo 2: pasi peMutemo 1, kuroora uye bipolar kutonga kunogona kushandiswa.

Mutemo 3: tendera inowirirana switch kunonoka kudzimwa.

Iko kukodzera uye kutadza kweswitch control zano pasi pekuchinja nyika kunoongororwa neanotevera ma index.

1.torque pulsation inokonzerwa nekuchinja idiki sezvinobvira (isiri yekuchinja ikozvino pulsation sediki sezvinobvira).

2. kupfupisa nguva yekuchinjisa kusvika pazvinogoneka.


Iine ETL, CE, ROHS, REACH chitupa, 60% yezvigadzirwa zveWonsmart zvinotumirwa kuNorth America, EU, Japan neKorea. Vatengi vanobva munyika idzi vanogutsikana neWonsmart yakagadzikana mhando, kukurumidza kuendesa uye mutengo unonzwisisika.

Isu tinogamuchirawo ODM uye OEM mapurojekiti uye akagadziriswa magadzirirwo.

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

Ndapota inzwa wakasununguka kuti utaure nesu.
