PWM (Pulse Width Modulation) inzira inoshandiswa zvakanyanya kudzora kumhanya nesimba rekutenderera kwemota dzeDC kana kuti dze vibration. Kana chiratidzo chePWM chakakwira chikashandiswa pamota, avhareji yemagetsi anotyaira mota ndiyo chiratidzo ichocho. Izvi zvinobvumira kudzora kumhanya kwemota nesimba rekutenderera. Ichi chishandiso chakakosha mumabasa akasiyana-siyana anosanganisira marobhoti, michina yeindasitiri, uye zvemagetsi zvevatengi.
Nzwisisa zvinhu zvepakutanga zvePWM signals
Kuti ushandise PWM kudzora kumhanya nesimba rekutenderera kwemota, zvakakosha kunzwisisa hwaro hwezviratidzo zvePWM. Chiratidzo chePWM chine mapuruse akatevedzana, apo upamhi hwepulse (hunonzi duty cycle) hunosarudza avhareji yevoltage inoshandiswa kumota. Nekugadzirisa duty cycle yechiratidzo chePWM, voltage inoshanda uye current inounzwa kumota zvinogona kudzorwa, nokudaro zvichigadzirisa kumhanya nesimba rekutenderera kwemota.
Kana uchishandisa PWM kunemota yekudedera yemari, frequency yechiratidzo chePWM inoita basa rakakosha pakuona mashandiro emota. Mafrequency ePWM akakwira anobvumira kudzora kumhanya kwemota zviri nyore uye zvakanyatsojeka uye simba rekuzunungusa. Uyezve, mafrequency ePWM anofanira kusarudzwa nokungwarira kudzivirira chero migumisiro isingafadzi yakaita seruzha runonzwika kana kuti mechanical resonance mumota.
Muenzaniso wemota inotyairwa nechiratidzo chePWM
Sarudza PWM controller kana microcontroller chaiyo
Kuti ushandise PWM zvinobudirira kudzora kumhanya kwemota yekudzungudza uye simba rekudzungudza, muchina wekutonga wePWM kana microcontroller akakodzera anofanira kusarudzwa anogona kugadzira chiratidzo chePWM chinodiwa. Muchina wekutonga unofanirwa kukwanisa kugadzira chiratidzo chePWM chine frequency yakakwira chine duty cycle inogadziriswa. Saka inogona kusangana nezvinodiwa zvekushandisa.
Pamusoro pezvo, zvakakosha kufunga nezvemota diki yekudedera's zvirevo uye hunhu hwekushanda pakushandisa PWM control. Zvinhu zvakaita sevoltage, current, mechanical, uye electrical hunhu hwemota zvinofanirwa kutariswa kuti zvive nechokwadi chekuti inoshanda zvakachengeteka uye zvinobudirira.
Maitiro ebasa rePWM
Muchidimbu
PWM chishandiso chine simba chekudzora kumhanya uye simba rekudedera kweMota yekudzungudza yeDCNekunzwisisa misimboti yezviratidzo zvePWM uye kusarudza PWM controller yakakodzera, kutonga kwakarurama uye kwakavimbika kwekushanda kwemota kunogona kuwanikwa. Iyi tekinoroji inokosha mukushandiswa kwekutonga kwemota uye kudedera.
Bvunza Nyanzvi dzeMutungamiriri Wako
Tinokubatsira kudzivirira matambudziko ekupa mhando yepamusoro uye kukoshesa zvaunoda, panguva uye nebhajeti.
