Qhov zoo thiab qhov tsis zoo ntawm DC brushless reducer

DC brushless reducer muaj cov yam ntxwv ntawm cov lus teb ceev ceev, loj pib torque, thiab ntsuas torque los ntawm xoom nrawm mus rau qhov ntsuas ceev. Txawm li cas los xij, qhov zoo ntawm DC lub cev muaj zog kuj yog nws qhov tsis zoo, vim tias DC lub cev muaj zog ua kom lub cev tsis tu ncua raws li qhov ntsuas ntsuas. Rau kev ua tau zoo tam sim ntawd, lub armature magnetic teb thiab rotor magnetic teb yuav tsum tau khaws cia ntawm 90 °, uas yuav tsum tau carbon txhuam thiab commutators. Cov txhuam hniav thiab cov commutator tsim cov pa roj carbon monoxide thaum lub cev muaj zog tig.

Yog li ntawd, ntxiv rau kev puas tsuaj rau cov khoom siv, kev siv cov pa roj carbon txhuam thiab cov commutators kuj raug txwv. DC brushless reducer tsis muaj cov txhuam hniav thiab cov commutator. Lawv yog cov tu-dawb, ruaj khov thiab dav siv. Txawm li cas los xij, cov txheej txheem tswj kev nyuaj yuav tsum tau siv los tswj cov yam ntxwv ntawm DC motors. Niaj hnub no' s semiconductors tab tom txhim kho sai, thiab kev hloov pauv ntawm cov khoom siv hluav taws xob tau nrawm dua, yog li txhim kho kev ua haujlwm ntawm lub cev muaj zog. Qhov ceev ntawm microprocessor tau nrawm dua thiab nrawm dua. AC lub cev muaj zog tswj tuaj yeem muab tso rau hauv kev sib hloov ob-axis Cartesian kev tswj hwm, thiab ob-axis tam sim no cov khoom ntawm AC lub cev muaj zog tuaj yeem tswj tau kom ua tiav DC lub cev muaj zog zoo sib xws, uas yog piv rau DC lub cev muaj zog. kev ua tau zoo.

Thaum tus naj npawb ntawm rotor ncej yog tsau, hloov qhov zaus ntawm stator rotating magnetic teb yuav hloov lub rotor ceev. DC brushless reducer yog lub cev muaj zog synchronous nrog hluav taws xob tswj (tsav), uas yog siv los tswj cov zaus ntawm stator rotating magnetic teb, thiab tawm tswv yim ceev ntawm lub cev muaj zog rotor mus rau qhov chaw tswj kom rov ua kom tiav cov yam ntxwv ze rau Cov yam ntxwv ntawm DC lub cev muaj zog. Nyob rau hauv lwm yam lus, thaum lub load hloov nyob rau hauv lub rated load range, DC brushless lub cev muaj zog tuaj yeem tswj lub cev muaj zog rotor kom tswj tau qhov ceev.
