Zamiana biegunów w silniku ele.

Witam. Poszukuje schematu który pozwolił by na zamiane biegunów w zwykłym silniczku elektrycznym. Inaczej mówiąc potrzebuje układ do sterowania silniczkiem (prawe obroty, lewe obroty) bez konieczności ręcznej zmiany biegunów.
Bede wdzięczny za wszelkie schematy i linki do stron związanych z tematem.

Witam; układ w WS504 nie rózni sie niczym od przedstawionego, poza tranzystorami i wartościami rezystorów (zasilanie z 5 voltów). To sa drobne subtelności. Takich rozaiązań sa setki, bo sam układ jest oczywisty i prymitywnie prosty. Można go spotkac w wielu starszych magnetofonach kasetowych połowy swiatowych firm; z innych jeszcze rozwiązań można zaproponować np. użycie układu BA6208. Ja swoje "trzy grosze" zamieszczam na Elenocie w sposób dostepny dla wszystkich, upatrując w tym pewna role edukacyjną - za "free" dla wszystkich zainteresowanych.

Witam dołączam dwa przykłady,jeden to fragment WS504, drugi pochodzi z Denona; dane scalaka sa w Elenocie.

Zobacz sobie l293 1 uklad ma dwa kompletne sterowniki za 10 zl.

weź przekaźnik z 2 stykami nc i no nic prostszego

2 przekaźniki

Zgadzam się z przedmówcą 2 przekaźniki i układ działa. Ponadto nie ma problemów z odprowadzaniem ciepła z np. tranzystorów.

Powyższy układ zawiera pewien poważny błąd: nie ma zabezpieczenia przed pojawieniem się równoczesnego sterowania ze strony transoptorów. To samo dotyczy czasów związanych z wychodzeniem transoptorów ze stanu włączenia. Po prostu wystarczy zbyt szybko zmienić stan transoptorów - tranzystory polowe ulegną zniszczeniu.
