Sesimba sosi yemagetsi emidziyo yemagetsi kana akasiyana muchina, basa rakakosha remota kukonzeresa torque yedhiraivha.

Kunyangwe iyo inoderedza mapuraneti ichinyanya kushandiswa pamwe chete ne servo motors uye stepper motors, ruzivo rwehunyanzvi rwemotor ruchiri kufarirwa zvakanyanya.Naizvozvo, handina kushivirira kuona iyi “chidimbu chekushanda kwemotokari kwakasimba kwazvo munhoroondo”.Dzoka kuzogovana nemunhu wese.

Brushless Direct Current Motor (BLDCM) inobvisa zvikanganiso zvemukati zvemabrashi eDC motors uye inotsiva mechaniki mota rotor nemagetsi mudziyo mota rotor.Naizvozvo, brushless yakananga yazvino mota dzine yakanakisa kusiyanisa kumhanya maitiro uye mamwe maitiro eDC motors.Iyo ine zvakare mabhenefiti eyakapusa chimiro chekutaurirana AC mota, hapana commutation murazvo, kushanda kwakavimbika uye nyore kugadzirisa.
Basic nheyo uye optimization algorithms.

Iyo BLDC mota yekudzora mirau inodzora chinzvimbo uye sisitimu yemota rotor iyo mota inovandudza kuita inogadzirisa.Kune yakavharwa-loop control rate manipulation, kune maviri ekuwedzera mirau, ndiko kuti, kuyera kwakaringana kwemota rotor kumhanya / kana mota ikozvino uye yayo PWM chiratidzo chekudzora kubuda kwesimba reye mota.

Iyo BLDC mota inogona kusarudza kutevedzana kwepadivi kana nzvimbo yekutonga kuteedzera chiratidzo chePWM zvinoenderana nemirairo yekushandiswa.Mazhinji maapplication anongoshandura mashandiro chaiwo pamwero wakatarwa, uye matanhatu akapatsanurwa edge-kutevedzana PWM masaini anozosarudzwa.Izvi zvinoratidza iyo yakanyanya skrini resolution.Kana iwe ukashandisa iyo yakatsanangurwa sevha yetiweki yekumisikidza chaiyo, simba-inopedza braking system kana kutyaira simba reversal, zvinokurudzirwa kushandisa iyo yakazadzwa manejimendi nzvimbo kuteedzera iyo PWM chiratidzo.

Kuti uite zvirinani chikamu cherotor cheiyo magineti induction mota, iyo BLDC mota inoshandisa Hall-effect sensor kuratidza iyo yakakwana yekumisikidza magineti induction.Izvi zvinokonzera kushandiswa kwakawanda uye mari yakakwirira.Inductorless BLDC Operation inobvisa kudiwa kwezvinhu zveHoro, uye inongosarudza iyo yega-induced electromotive simba (induced electromotive simba) yemota kufanotaura uye kuongorora chikamu cherotor chemota.Sensorless mashandiro akanyanya kukosha kune yakaderera-yekumhanyisa kudzora zvikumbiro senge kutonhora mafeni nemapombi.Paunenge uchishandisa BLDC mota, mafiriji nemacompressor anofanirwawo kushanda pasina inductors.Kuiswa uye kuzadza kwenguva yakazara mutoro
Mazhinji eBLDC mota haadi inopindirana PWM, yakazara mutoro nguva yekuisa kana yakazara mutoro wenguva muripo.Zvingangoita kuti BLDC zvikumbiro zvine hunhu uhwu zvinongo shanda BLDC servo motors, sine-wave inokurudzirwa BLDC mota, brushed motors AC, kana PC synchronous motors.

Mazhinji akasiyana masisitimu ekudzora anoshandiswa kuratidza mashandisirwo eBLDC mota.Kazhinji, iyo inobuda simba transistor inoshandiswa seye mutsara inodzorwa magetsi ekushandisa kushandisa simba rekushanda remota.Iyi mhando yenzira haisi nyore kushandisa kana uchityaira mota ine simba guru.High-power motors inofanira kushandiswa nePWM, uye microprocessor inofanira kutsanangurwa kuratidza kutanga uye kutonga mabasa.

Iyo control system inofanirwa kuratidza anotevera mabasa matatu:

PWM inoshanda voltage inoshandiswa kudzora kumhanya kwemota;

Iyo sisitimu inoshandiswa kushandura mota mune inogadzirisa;

Shandisa self-induced electromotive force kana Hall element kufanotaura uye kuongorora nzira yemotor rotor.

Iyo pulse hupamhi inogadziriswa inongoshandiswa kuisa iyo inoshanduka yekushanda voltage kune iyo mota inotenderera.Iyo inonzwisisika yekushanda voltage inodyidzana zvakanaka nePWM duty cycle.Kana iko kugadziridza kwakaringana kunowanikwa, iyo torque rate hunhu hweBLDC hwakafanana neinotevera DC mota.Iyo inoshanduka inoshanda voltage inogona kushandiswa kushandura kumhanya uye kusiyanisa torque yemota.
