Kushandiswa kweMOSFET mudhiraivha yeDC brushless mota

Muhupenyu hwedu hwemazuva ese, DC brushless motors haina kujairika, asi kutaura zvazviri, DC brushless motors, iyo inoumbwa nemota muviri uye mutyairi, yava kushandiswa zvakanyanya muminda yepamusoro-soro senge mota, maturusi, maindasitiri kutonga, otomatiki uye. Aerospace, nekuda kwekuita kwayo kwakavimbika, hapana kupera uye kubvaruka, mwero wakaderera wekutadza, tarisiro yehupenyu kupfuura mota yakabhurwa yakawedzera nekanosvika ka6 uye zvimwe zvakanakira. Imhaka yekuti iyo DC brushless mota ine basa rakakosha kudaro, zvekuti kuti ipe kutamba kwakazara kuita kwayo, sarudza yakanaka MOSFET yekutyaira dunhu yakakoshawo.

Motokari yeDC ine kukurumidza kupindura, kutanga torque, kubva zero kumhanya kusvika yakayerwa kumhanya inogona kupa yakayerwa torque kuita, asi zvakanakira iyo DC mota zvakare kukanganisa kwayo, nekuti iyo DC mota kuitira kuti igadzire inogara torque pasi peyakayerwa mutoro kuita, iyo armature magineti uye rotor magineti inofanirwa kuchengetedzwa inogara iine 90 °, iyo inoda kuzadzikiswa nekabhoni mabhurashi uye inogadzirisa. Carbon brushes uye rectifiers zvinogadzira sparks uye carbon dust kana mota ichitenderera, saka mukuwedzera mukukonzeresa kukuvadza kune zvikamu, zvinogona kushandiswa mune mashoma maapplication.

Kana iwe uchida kuvandudza kushanda kwemotokari yemotokari, unofanira kutanga kubva kune zvikamu zvemagetsi, aMOSFETiyo inokwanisa kutyaira dunhu zvakanaka kwakakosha, kune izvi kuita zvinodiwa zveDC brushless mota, Guanhua Weiye ine yakakosha N-channel yekusimudzira ye-high-voltage simba FETs, ine yakaderera charge, yakaderera reverse transfer capacitance, kukurumidza kushandura kumhanya uye mamwe maitiro.

Panguva imwecheteyo, izviMOSFETinogona zvakare kushandiswa kutyaira welding michina uye switching magetsi ekushandisa.
