Imodi yokulawula isivinini samandla e-DC brushless motor njalo

Ingabe lokho okubizwa ngokuthi ukulawulwa kwesivinini kazibuthe esibuthakathaka, le ndlela yokulawula isivinini, ingqikithi iyindlela yokulawula isivinini se-torque engapheli yesithasiselo, ikakhulukazi izikhathi ezithile, isidingo sokulawulwa kwejubane okubanzi, njengombhede we-gantry, isidingo sokubaI-DC brushless motorukucubungula lapho ukuphakelwa kuhamba kancane, i-torque iphakeme kakhulu; Futhi emuva lapho i-torque ilula kakhulu izogijima ngokushesha okukhulu, ngalesi sikhathi lapho ummese onemodi yokulawula ijubane letorque engashintshi, futhi ubuye lapho imodi yokulawula ijubane kazibuthe ebuthakathaka, ngalesi sikhathi amandla aphezulu enjini ayafana.

Kukhona futhi izimoto zikagesi, isivinini esiphansi sokukhuphuka ukuze zihambe kancane kakhulu, zidinga i-torque eningi, futhi ukumelana nomgwaqo oyisicaba kuncane futhi zifuna ukugijima kakhulu, kulokhu kudingeka futhi kusetshenziswe ukulawulwa kwejubane lamandla njalo, okufana nendlela ukushintshwa komshini noma ukulungiswa kwesilinganiso sejubane ukuya kumthethonqubo wesivinini.Isimiso sokulawula isivinini kazibuthe esibuthakathaka, asifanele motor kazibuthe unomphela, ngakho-ke i-flux kazibuthe Φ ayikwazi ukulawulwa ngokuhlukana.
Ukwenza buthaka inkambu kazibuthe, ukunciphisa ngokuqondile usayizi we-air gap flux Φ, ngalesi sikhathi kunganciphisa ukusebenza kwekhoyili evusa amadlingozi, ngokuvamile kukhoyili evusa amadlingozi izosebenzisa i-silicon elawulwayo noma ishubhu lomphumela wensimu lawa ukuze enze ukulungiswa kwe-PI. buyela ekukhipheni umthombo wamanje ozowufeza.
Uma ukulawulwa kwesivinini kazibuthe esibuthakathaka, ukuphakama kwejubane lemoto, kuncane umkhawulo wetorque ephumayo yenjini, okufanele kuqashelwe, futhi ngokuvamile okungancishiswanga okungenamkhawulo, cishe kungalawulwa cishe ku-90% we-excitation current.
