Kia pehea te tika o te mana o te aukume tuturu brushless dc moto commutation i muri i te utu o naianei, ara me pehea te whakahaere tika i te PWM100 % te wa huringa mahi ko te matua ki te hoahoatanga kaiwhakahaere wahangu! Ko te tikanga tenei ko te punaha whakahaere MCU nga ahuatanga e whai ake nei:
1) Kaore i roa ka huri te tere o te A/D, ka taea te whakatauira tere tonu i muri i te whakawhiti;
2)I roto i te PWM i te wa whakatuwheratanga o te wa motuhake te whakaoho A/D sampling; Na te mea kei roto i te PWM inverter me te punaha whakahaere kawenga perceptual, na etahi tawhā piriti o te punaha o te PWM i te wa e tuwhera ana, e tutakina ana te tangi o te raina wahanga motuka (penei i te ahua 4), ka honoa te tangi ki te tauira A/D. iahiko, na me karo tatou i roto i te tukanga o te whakawhiti PWM ki te A/D sampling. Mena ka whakakorikori tatou i te naianei i te waahi o te PWM i whakatuwheratia i te wa o te whakatauira, ko tatou te toharite o te ia, ka pai ki a tatou te whakahaere i nga utu o naianei.
i roto i te meka, ehara i te mea uaua ki te kimi i taua MCU, penei i te maramara mana motopaika motuhake XC866 infineon, maramara maramara mana programmable CY8C24533 me CYPRESS, me etahi atu. Ka taea e te XC866 A/D te tere huringa te tae ki te 2 i roto i a maatau, me te wa mahi o te kaupapa. , he huringa A/D ki te wa katoa i roto i te tokowaru o matou, i taua wa ka oti te waa ki te whakatau mena te utu o naianei. Ko te CY8C24533 CYPRESS he mea tino hangaia mo te whakawhanaketanga whakahaere motuka me te maramara A / D tere tere, i roto i tana tere huringa SAR8 ka taea te tae ki te 3 tatou, ka honoa me te aratau whakaoho aunoa, A / D ka taea te whakaoho i nga wa katoa i roto i te PWM o naianei A / D sampling, he ngawari hoki ki te mohio ki te mana tika o te naianei.
Ko te ahua 2 b ko te punaha e WHAKAMAHI ana i te maramara mana XC866 i muri i te arotautanga o te ine i roto i nga waahanga ngaru o naianei, ka kitea mai i te ahua 2 b, ka whakakorehia te tere o naianei, tata ki te waahanga ngaru tapawha o naianei o te motuka. I roto i te punaha whakahaere o te waka hiko, kua whakakorehia te wiri motika ki te whakatere me te wa omaoma, kua mohiohia te hoahoa kaiwhakahaere ultra-ata.
Ko te roopu HOPRIO he kaihanga ngaio o te kaiwhakahaere me nga motuka, i whakapumautia i te 2000. Te tari matua o te roopu i Changzhou City, Jiangsu Province.
