Mōta DC kore paraiheKo te (BLDC) he motuka whai hua nui, he iti te haruru, he roa te ora e whakamahia whānuitia ana i roto i ngā momo mara, pērā i te aunoatanga ahumahi, ngā taputapu hiko, ngā waka hiko, me ētahi atu. Ko te whakahaere tere he mahi nui o te whakahaere motuka DC kore paraihe. Ka whakaatuhia i raro nei ētahi tikanga whakahaere tere motuka DC kore paraihe noa.
1. Te whakahaere tere o te ngaohiko
Ko te whakahaere tere o te ngaohiko te tikanga whakahaere tere māmā rawa atu, e whakahaere ana i te tere o te motuka mā te whakarerekē i te ngaohiko o te pūtake hiko DC. Ina piki te ngaohiko, ka piki anō hoki te tere o te motuka; i tetahi atu taha, ina heke te ngaohiko, ka heke anō hoki te tere o te motuka. He māmā noa iho tēnei tikanga, ā, he ngāwari ki te whakatinana, engari mō ngā motuka mana-nui, kāore te pānga o te whakahaere tere ngaohiko i te tino pai, nā te mea ka heke te whai huatanga o te motuka i te pikinga o te ngaohiko.
2. Te whakahaere tere PWM
Ko te whakahaere tere o te PWM (Pulse Width Modulation) he tikanga noa mō te whakahaere tere o te motuka, e whakahaere ana i te tere o te motuka mā te whakarerekē i te huringa mahi o te tohu PWM. Ina piki te huringa mahi o te tohu PWM, ka piki anō hoki te ngaohiko toharite o te motuka, ā, ka piki ake te tere o te motuka; i tetahi atu taha, ina heke te huringa mahi o te tohu PWM, ka heke anō hoki te tere o te motuka. Ka taea e tēnei tikanga te whakatutuki i te whakahaere tere tika, ā, he pai mō ngā motuka DC kore paraihe o ngā mana rerekē.
3. Te whakahaere tere urupare pūoko
Ko ngā motuka DC kore paraihe he mea whakauru ki ngā pūoko Hall, ki ngā encoder rānei. Mā te urupare a te pūoko ki ngā mōhiohio tere me te tūranga o te motuka, ka taea te whakahaere tere porowhita-katia. Ka taea e te whakahaere tere porowhita-katia te whakapai ake i te pumau me te tika o te tere o te motuka, ā, he pai mō ngā wā e hiahiatia ana he tere teitei, pērā i ngā taputapu miihini me ngā pūnaha aunoa.
4. Te whakahaere tere urupare o nāianei
Ko te whakahaere tere urupare o te au he tikanga whakahaere tere e ahu mai ana i te au o te motuka, e whakahaere ana i te tere o te motuka mā te aroturuki i te au o te motuka. Ina piki te kawenga o te motuka, ka piki anō hoki te au. I tēnei wā, ka taea te pupuri i te tere pumau o te motuka mā te whakanui ake i te ngaohiko, te whakarerekē rānei i te huringa mahi o te tohu PWM. He pai tēnei tikanga mō ngā āhuatanga e tino rerekē ana te kawenga motuka, ā, ka taea te whakatutuki i te mahi urupare hihiri pai ake.
5. Te tūnga o te papa aukume kore-pūoko me te whakahaere tere
Ko te whakahaere tere o te papa aukume kore-pūoko he hangarau whakahaere tere matatau e whakamahi ana i te kaiwhakahaere hiko i roto i te motuka hei aroturuki me te whakahaere i te papa aukume o te motuka i te wā tūturu kia tutuki ai te whakahaere tika o te tere o te motuka. Kāore e hiahiatia he pūoko o waho i tēnei tikanga, ka māmā ake te hanganga o te motuka, ka whakapai ake i te pono me te pumau, ā, he pai mō ngā āhuatanga he nui te rōrahi me te taumaha o te motuka.
I roto i ngā mahi whaihua, ka whakakotahihia ngā tikanga whakahaere tere maha kia tika ake ai, kia pumau ake ai te whakahaere motuka. Hei tāpiri, ka taea te whiriwhiri i te kaupapa whakahaere tere e tika ana kia rite ki ngā tono me ngā whakaritenga motuhake. Kei te whanake tonu, kei te whakapai ake hoki te hangarau whakahaere tere o ngā motuka DC kore paraihe. I ngā rā kei te heke mai, ka puta ake he tikanga whakahaere tere auaha ake hei whakatutuki i ngā hiahia o te whakahaere motuka i roto i ngā mara rerekē.
