Dobry den,<br>
<br>
este jeden namet. Na prepinanie smeru otacania motora pouzit relatko
s dvoma prepinacimi kontaktmi a PWM robit iba jednym tranzistorom.<br>
Stredne kontakty k motoru, prvy kontakt NO na Vcc, NC na PWM, druhy
kontakt NO na PWM a NC na Vcc.<br>
<br>
Pripadne pouzit dve rele, potom je v polohe [obe rele vypnute | obe
rele zapnute ] funkcia "motorova brzda".<br>

<p>Vsak prave preto s tym teraz ponahlam a som ochotny vypustit
vsetku elektroniku az na to posledne relatko :) Sice su obidvaja
presvedceny, ze im to auto vydrzi este dlho, ale uz sa pod nimi
divne prehyba... Na druhu stranu, to pridrzanie istica pri
rozbehu uz videli aj svojho tatka robit, to by im nemuselo byt
uplne cudzie :) Dakujem teda vsetkym za podnety, idem sa s tym
dnes este trocha potrapit a na vikend im dam zas to relatko na
plnu rychlost...</p>

<div class="moz-cite-prefix">uz to vidim... detske auticko,
pripojene zvazkom kablov ku dvanastim rackom plnych vykonovej
a riadiacej elektroniky. Plynule rozjazdy, naprogramovane
vsetky rychlosti, zrychlenia a ryvy, ochrany proti pretazeniu
a vysokej rychlosti, riadeny odber zo siete pocas
energetickeho minima. Jaro to uspesne dokonci tak asi o 15
rokov, ked uz budu jeho synov viac zaujimat spoluziacky ako
auticko na elektricky pohon :-)<br>

<p>Ano, to by islo na ten PWM fault vstup. Musim pozriet do
datasheetu procesora, ci ho ma. Poistky som pri poslednom
nakupe v TME zobral az do 35A, takze chalanom vysvetlim
aby sa nepriputali a utekali pri prvom naznaku smradu a
tepla spod sedadiel :)<o:p></o:p></p>
