Preh\u013ead o trvalom magnetickom gener\u00e1tore: \u010co ho rob\u00ed funk\u010dn\u00fdm?<\/h1>\n

Ak v\u00e1s zauj\u00edma, ako tento typ gener\u00e1tora funguje, alebo \u010di m\u00f4\u017eete svoj motor premeni\u0165 na jeden z nich, nie ste sami. Rozkreslime to v\u0161etko.<\/p>\n

Ako funguje trval\u00fd magnetick\u00fd gener\u00e1tor?<\/h2>\n

Pr\u00e1ve\u017ee si \u013eudia myslia, \u017ee gener\u00e1tory potrebuj\u00fa zlo\u017eit\u00e9 polov\u00e9 cievky alebo extern\u00fa energiu na fungovanie. Nie v\u017edy je to pravda.<\/p>\n

Trval\u00e9 magnetick\u00e9 gener\u00e1tory funguj\u00fa prostredn\u00edctvom elektromagnetickej indukcie, pri\u010dom magnety pripojen\u00e9 k rotor s\u00fa schopn\u00e9 indukova\u0165 pr\u00fad v pevn\u00fdch cievkach.<\/strong><\/p>\n

Veda za silou<\/h3>\n

Nastavenie rotora a statora:<\/strong> V trvalom magnetickom gener\u00e1tore rotor obsahuje trval\u00e9 magnety. Tieto magnety sa ot\u00e1\u010daj\u00fa v bl\u00edzkosti statora, ktor\u00fd dr\u017e\u00ed cievkov\u00e9 vinutie z medi. Ke\u010f sa rotor ot\u00e1\u010da, pohybuje magnetick\u00fdm po\u013eom okolo cievok. Tento pohyb sp\u00f4sobuje nap\u00e4tie elektromagnetickou indukciou.<\/p>\n

Faktory v\u00fdstupn\u00e9ho v\u00fdkonu:<\/strong> Sila magnetick\u00e9ho po\u013ea, r\u00fdchlos\u0165 ot\u00e1\u010dania, po\u010det z\u00e1vitov cievky a materi\u00e1l jadra v\u0161etko ovplyv\u0148uj\u00fa mno\u017estvo generovan\u00e9ho elektrick\u00e9ho pr\u00fadu.<\/p>\n\n\n\n\n\n\n\n\n

Tento dizajn eliminuje potrebu preru\u0161en\u00fdch kontaktov alebo uhl\u00edkov\u00fdch kefiek. To zni\u017euje opotrebenie a \u00fadr\u017ebu.<\/p>\n

M\u00f4\u017ee sa permanentn\u00fd magnetov\u00fd motor pou\u017ei\u0165 ako gener\u00e1tor?<\/h2>\n

Mnoh\u00ed in\u017einieri sa na to p\u00fdtaj\u00fa, ke\u010f sa sna\u017eia u\u0161etri\u0165 \u010das a n\u00e1klady.<\/p>\n

\u00c1no, motor s permanentn\u00fdm magnetom m\u00f4\u017ee by\u0165 pou\u017eit\u00fd ako gener\u00e1tor, ale iba ak je spr\u00e1vne navrhnut\u00fd a pou\u017eit\u00fd v spr\u00e1vom zapojen\u00ed.<\/strong><\/p>\n

 <\/p>\n

Pre\u010do to funguje a kedy to nefunguje<\/h3>\n

PM motor a PM gener\u00e1tor zdie\u013eaj\u00fa podobn\u00e9 komponenty: rotor s magnetmi a stator s cievkami. Ke\u010f prech\u00e1dzate elektrinou cez PM motor, rotor sa to\u010d\u00ed. Ak v\u0161ak mechanicky oto\u010d\u00edte rotor, indukuje sa elektrina v statore \u2014 presne ako pri gener\u00e1tore.<\/p>\n

Existuj\u00fa v\u0161ak niektor\u00e9 rozdiely, ktor\u00e9 treba zv\u00e1\u017ei\u0165:<\/p>\n\n\n\n\n\n\n\n\n

V mnoh\u00fdch dom\u00e1cich alebo mal\u00fdch nastaveniach je pou\u017eitie motora ako gener\u00e1tora v poriadku. Ale pri kritick\u00fdch syst\u00e9moch odpor\u00fa\u010dam pou\u017ei\u0165 spr\u00e1vny PMG, aby sa predi\u0161lo strat\u00e1m alebo prehriatiu.<\/p>\n

M\u00f4\u017ee permanentn\u00fd magnet generova\u0165 elektrinu?<\/h2>\n

Znie to ako vedeck\u00e1 fikcia, ale je to skuto\u010dnos\u0165 a u\u017e sa to pou\u017e\u00edva v\u0161ade.<\/p>\n

\u00c1no, permanentn\u00fd magnet m\u00f4\u017ee Generova\u0165 elektrinu, ke\u010f sa pohybuje vo vz\u0165ahu k cievke, na z\u00e1klade princ\u00edpu elektromagnetickej indukcie.<\/strong><\/p>\n

 <\/p>\n

Nie k\u00fazlo, len fyzika<\/h3>\n

\u78c1\u00fa magnets neprodukuj\u00fa elektrinu samy o sebe. Vy\u017eaduj\u00fa pohyb. Ke\u010f sa magnet pohybuje bl\u00edzko vodivej \u010dasti, sp\u00f4sobuje pohyb elektr\u00f3nov \u2014 to je elektrick\u00fd pr\u00fad. Preto PMG maj\u00fa rotor, ktor\u00fd ot\u00e1\u010da magnety popri cievkach.<\/p>\n

V\u00fdroba elektriny z\u00e1vis\u00ed od troch k\u013e\u00fa\u010dov\u00fdch vec\u00ed:<\/p>\n

    \n
  • Sila magneta<\/strong>: Silnej\u0161ie magnety generuj\u00fa viac pr\u00fadu.<\/li>\n
  • R\u00fdchlos\u0165 pohybu<\/strong>: R\u00fdchlej\u0161\u00ed pohyb = vy\u0161\u0161\u00ed v\u00fdstup.<\/li>\n
  • Vzdialenos\u0165 od cievky<\/strong>: \u010c\u00edm bli\u017e\u0161ie = silnej\u0161ia indukcia.<\/li>\n<\/ul>\n

    Tento princ\u00edp stoj\u00ed za vetern\u00fdmi turb\u00ednami, dynama na bicykli a dokonca aj mal\u00fdmi ru\u010dn\u00fdmi nab\u00edja\u010dkami. V ka\u017edom pr\u00edpade pohyb magnetov vzh\u013eadom na cievky vytv\u00e1ra pou\u017eite\u013en\u00fa energiu.<\/p>\n
