Me pehea e mahi ai te Inductor Tūmau?

E mahi ana te inductor tūmau mā te hanga me te pupuri pūngao i roto i te papa rūnanga ina te mana hiko e rere ana i roto i tana taura. I te whakarapopototanga i te whakaahua i raro nei, ko te taura pātea e whakapiri ana ki tetahi rauemi pūrākau, ā, ina ka tukuna te voltage ki ngā pōkai, ka tīmata te mana e rere ana i roto i te taura. Ka hanga tēnei mana i te papa rūnanga i raro i ia huringa o te taura. Ka whakakotahi ngā papa rūnanga takitahi hei hanga i te papa rūnanga kaha, e tohu ana i ngā raina kowhai pērā me ngā riu e karapoti ana i te inductor. Ka awhina te rauemi pūrākau ki te whakakotahi i te pēhanga rūnanga, e whakakotahi ana i te inductance me te whakakaha i te āheinga o te inductor ki te pupuri pūngao.

I a ka nui haere te mana, ka whakawhānui te papa rūnanga, kāore e pupuri pūngao i roto i te papa rūnanga e karapoti ana i te taura. Ko tetahi o nga āhuatanga tino nui o te inductor tūmau ko tōna āheinga ki te tautoko i ngā huringa ohorere i te mana. Ina ka whakamātau te mana ki te pākū i te tere, ka hanga te papa rūnanga e whakawhānui ana i te voltage e pānui ana i te pākiki. Ka pēnā, ina ka tīmata te mana ki te heke, ka whakaputa te papa rūnanga e heke ana i te voltage ka tūtohu ki te pupuri i te rere o te mana. Ko tēnei hītori, e mōhiotia ana hei inductance pōturi, ka awhina ki te whakatika i ngā huringa mana i roto i te hātepe.

Ka tangohia te pūngao mai i te puna pūngao, kāore e heke te mana, ka whakararu te papa rūnanga ka tuku te pūngao e pupuri ana ki te hātepe. Ko tā rātou āheinga ki te pupuri pūngao rūnanga me te aukati i ngā tāparutanga tere o te mana hei āhuatanga tino nui i roto i te maha o ngā pūnaha hiko.
