E whakamārama ana tēnei tuhinga i ngā āhuatanga matua o te whiriwhiri, ngā mōrearea rahunga noa, me ngā paearu mahi e āwhina ana i ngā kaihangarau me ngā tīma tiaki ki te whakatau i ngā peera motuka pono ake.

He aha te hiranga o ngā peera motuka mō te pono o te ahumahi

Ko ngā motuka hiko te kaiārahi i ngā umanga hou, engari ko tōna pono e whakawhirinaki ana ki tētahi o ngā wāhanga miihini iti rawa:ngā peera motukaHei hononga matua i waenga i te whare stator tūmau me te pou hurihuri, me tu atu ngā peera i ngā kawenga radial me te axial matatini, me te whakaiti i te waku puta noa i ngā miriona huringa hurihuri.

He pēhea te pānga o ngā peera motuka ki te wā mahi, te wiri, me te pūngao?

Ka whakatau tika ngā peera i te whai huatanga ā-pūkaha me te waitohu oro ongā motuka ahumahi. Mā te nui rawa o te waku mai i te kōwhiringa o te peera, te whakahekenga rānei, ka taea te whakaiti i te pai o te motuka katoa mā te 1.5% ki te 3.0%, ka huri ki ngā mano tāra i roto i te pūngao e maumauria ana i roto i te huringa ora o te motuka 100-horsepower. Hei tāpiri, ka mau tonu te tūnga o te pou e ngā peera tika, ka pupuri i ngā tere wiri i raro i te paepae matua 2.8 mm/s (e ai ki ngā paerewa ISO 10816 mō te mahi tonu), e ārai ana i te kino tuarua ki ngā hononga, ngā hiri, me ngā taputapu kua peia.

Ko ēhea ngā momo rahunga e tino hua ake ai ngā momotu o te peera motuka kāore i whakamaheretia

E whakaatu tonu ana ngā raraunga ahumahi ko ngā peera te take o te 51% o ngā pakaru katoa o te motuka hiko. Ko te momo pakaru tino kitea ko te pakaru hinu, e 80% pea o aua motumotu e pā ana ki te peera. Ko ētahi atu momo kino ko te rere o te hiko—ko te ia o ngā ia o te rakau e neke atu ana i te 1.5 volts ka piko mā roto i te kiriata hinu angiangi, ka puta he poka iti i runga i te ara rere—me te poke totoka. Ina tere haere ēnei tikanga pakaru, ka taea e te roanga o te ora L10 o te peera (e kiia ana i te 40,000 ki te 100,000 hāora) te heke ki ngā marama noa iho o te ratonga tuturu.
