I roto i ngā tau maha e tuku ana i ngā motuka DC moroiti ki ngā kaihoko motuka, hauora, me ngā kaihoko hikohiko, kua kohia e mātou ngā pātai e pātai pinepinetia ana. Anei ngā pātai matua e rima, me ngā whakautu whai hua mai i tā mātou tīma miihini wheketere.
Q1: He nui ake te haruru o taku motuka i tō te whakaaro – he aha te raru?
Ko te haruru i te nuinga o te wā ka puta mai i ngā pūtake miihini, hiko rānei. Mīhini: tirohia mēnā he roa rawa ngā tīwiri whakairi, ka pā ki roto, mēnā rānei kāore i te tika te hononga o te pou. Hiko: ka puta he haruru mura i ngā motuka paraihe; mā te tāpiri i te pūnga uku (0.1µF) puta noa i ngā pito ka taea te whakaiti. Mō te tangi auau teitei tonu, huri ki te motuka BLDC, ki te motuka kore-matua rānei.
Q2: Kāore te motuka e tīmata i ngā wā katoa, e tū rānei i raro i te kawenga māmā.
He maha ngā wā he hekenga ngaohiko tēnei, he kore rānei e ranea te taipana tīmatanga. Inehia te ngaohiko i ngā pito o te motuka – ka taea e ngā waea roa, angiangi te heke nui. Waihoki, me nui ake te ia tīmatanga o ngā motuka moroiti i te ia e rere ana. Me whakarite kia taea e tō pūtake hiko te tuku i te iti rawa i te rua o te ia tū kua whakatauria mō ētahi mirihekona. Mena kei te mau tonu te raruraru, ngana ki te whakamahi i tētahi motuka he nui ake te taipana tū, he iti ake rānei te ōwehenga taputapu.
Q3: Me pēhea taku tiaki i te motuka mai i ngā take EMC/EMI?
He rongonui ngā motuka paraihe mō ngā tukunga ira me ngā tukunga ka tukuna. Ngā whakatikatika māmā:
Ngā pūnga honohono (te nuinga o te wā 0.1µF + 0.01µF) mai i ia pūrua ki te pouaka.
Whakamahia ngā waea takirua miro me te titi ferrite tata ki te mōta.
Mō te tutuki i ngā whakaritenga (hei tauira, mō ngā whakaritenga hauora, mō ngā whakaritenga motuka rānei), whakaarohia he motuka BLDC – he iti ake te pokanoa e puta mai ana i tana whakawhiti hiko.
Q4: He aha te pāmahana mahi haumaru?
Ko te nuinga o ngā motuka DC moroiti e whakamahi ana i te whakamarumaru akomanga E (120°C) akomanga B rānei (130°C). Me noho tonu te pāmahana taiao me te whakamahana-ake i raro i tēnei rohe. Hei tikanga, kaua te anga motuka e neke ake i te 85°C mō ngā motuka paraihe, 100°C rānei mō te BLDC. Ka pakaru ngā aukume me ngā hinu whakahinuhinu i te pāmahana teitei. Mō ngā taiao wera (hei tauira, ngā wāhanga miihini), tonoa he aukume me te hinu pāmahana teitei.
Q5: Me pēhea te whakaroa i te roa o te ora o te motuka ina mahi tonu?
Ka herea te roa o te ora e te pakaru o te paraihe (ngā motuka paraihe) te pakaru rānei o te peera (ngā motuka katoa). Hei whakanui ake i te roa o te ora:
Whakahaerehia i te ngaohiko iti rawa e rite ana ki tō tere/taipana – he iti ake te wera, he iti ake te pakaru o te paraihe.
Āta karohia ngā huringa tīmatanga/mutu – ka nui ake te ia o te paraihe i ia tīmatanga.
Puritia te puehu me te makuku kia kore e uru – whakamahia he ārai IP kua whakatauria, tāpirihia rānei he hiri pou.
Mō ngā mahi 24/7, huri ki te motuka BLDC – kāore te roa o te paraihe e herea ana.
