Puku auau: whakaahuatanga me arotake

puku auau ture taea te whakamahi i te pūtahuri motuhake ki ngāwari te huri i te aratau mahi o te nekeneke: kia tīmata ai, mutu, whakaterenga, braking, te huri i te tere o te hurihanga.

Te huri i te auau o te ngaohiko supply arata'i ki te huringa i roto i te tere koki o te papa autō o te stator. A, no te heke te auau, heke te tere pūkaha, me nga piki pepa.

Ko te parau tumu o te mahi o te puku pūtahuri auau

Ko te drawback matua ko te whīwhiwhi o tukutahingakore motors tere ture tikanga tikanga: te huri i te ngaohiko me te introduction o kopiko atu i roto i te parenga iahiko. More mātanga ko te auau puku o te nekeneke. Tae noa tata, nga pūtahuri pricey, engari te ahua o te IGBT-transistors me ngā pūnaha whakahaere microprocessor whakaaetia kua kaiwhakanao ke ki te hanga i utu utu o te pūrere. Ko te noaa teitei tenei ra he pūtahuri auau pateko.

Ko te tere koki o te ω stator papa autō ₀ huringa i roto i te rahi ki te auau ƒ ₁ rite ki te tātai:

ω ₀ = 2π × ƒ ₁ / p,

te wahi p - maha o pou takirua.

E whakarato ana te tikanga mo te mana tere ngawari. I tenei tere e kore e nui haere te pepa nekeneke.

Ki te whiwhi mahi nui mana o te pūkaha - te pai, te mana tauwehe me te wa āheinga kikī, me ki te auautanga o te huri faaotiraa ngaohiko whakawhirinaki:

• taipana kawenga tamau - U ₁ / ƒ ₁ = const;
• Fan kawenga pūāhua taipana - U ₁ / ƒ ₁ ² = const;
• Ko inversely hautanga ki te tere kawenga taipana - U ₁ / √ ƒ ₁ = const.

E whakatinanahia ēnei mahi mā te transducer i te huri i te auau me te ngaohiko ki te stator nekeneke. Tiaki mana e whakahaere mā te tika tawhā tukanga: pēhanga papu, kaha tahi, te auau kai o te mīhini, me ētahi atu nga tawhā rerekē pai ..
