Chii chinonzi brushless motor--kushanda musimboti

Iyo brushless DC yemagetsi mota (BLDC mota kana BL mota) inoshandisa semiconductor switching madivayiri kuona emagetsi commutator, kureva kuti, magetsi ekuchinja maturusi pachinzvimbo chechinyakare chekusangana commutator uye bhurashi.Ine zvakanakira kuvimbika kwepamusoro, hapana spark inotenderera, yakaderera mechanic ruzha. zvichingoenda zvakadaro.Inoshandiswa zvakanyanya muchigaro chepamusoro chekurekodha, vhidhiyo rekodhi, chiridzwa chemagetsi uye hofisi otomatiki michina.

Brushless DC mota inoumbwa neperformance magnet rotor, multi-pole winding stator uye position sensor.Position sensing maererano nekuchinja kwerotor position, pamwe neimwe kutevedzana kwe stator winding current converter (kureva kuona rotor magnetic pole inoenderana nenzvimbo ye stator winding. , uye pakusarudza nzvimbo yechiratidzo che sensor sensor, chiratidzo chekushandura chiratidzo chekugadzirisa simba rekushandura remagetsi, mushure mekugadzirisa maererano nehumwe hukama huri pakati pemhepo yekushandura ikozvino) . nekubuda kwenzvimbo sensor.

Kune marudzi matatu ezvinzvimbo sensors: magineti-sensitive, photoelectric uye electromagnetic.

Brushless DC mota ine magineti-sensitive chinzvimbo sensor, yayo magineti-sensitive sensor zvikamu (senge horo element, magineti-sensitive diode, magineti-sensitive pole chubhu, magineti-sensitive resistor kana yakakosha yakabatanidzwa dunhu, nezvimwewo) yakaiswa pane stator. musangano kuona shanduko yemagineti inokonzerwa nekusingaperi magineti uye kutenderera kwe rotor.

Iyo brushless DC mota ine photoelectric position sensor inoshongedzerwa ne photoelectric sensor pane imwe nzvimbo pamusangano we stator, chidzitiro chinoiswa pane rotor, uye chitubu chemwenje chinotungamirwa kana diki girobhu.Apo rotor iri kutenderera, nekuda kwebasa. yevhavha, iyo photosensitive components pane stator ichaita intermittently kubudisa pulse zviratidzo pane imwe frequency.

Kushandisa electromagnetic chinzvimbo sensor brushless dc mota, iri mumagetsi magineti sensors akaiswa pane stator chikamu zvikamu (senge coupling transformer, padhuze nekuchinja, LC resonance circuit, nezvimwewo), kana inogara magineti rotor chinzvimbo ichichinja, electromagnetic mhedzisiro ichaita. ita iyo electromagnetic sensor inogadzira yakakwira frequency modulation siginecha (iyo amplitude inoshanduka neiyo rotor chinzvimbo)
