    Salve, avendo trovato una svendita di un azienda in chiusura riesco a prendere dei motoriduttori 24v a 16 euro. Per un 6dof alla fine si spendono 96 euro.
    Essendo un ottimo prezzo e i motoriduttori molto robusti vorrei prenderli ma non so quale ponte ad H utilizzare per farli funzionare.
    Ne ho già presi 2 per il 2dof dove userò la vellemank8055 + sabertooth ma nel 6 dof vorrei utilizzare 3 auduino uno.
    cosa mi consigliate?
    Per l' alimentazione nessuno ha provato a mettere in serie due alimentatori da 12v?
    So che in teoria si può fare ma non so se ci sono controindicazioni.


    Hi, having found a sale to a company in closing seem to take 24v gearmotors to 16 euros. For a 6dof ultimately spend 96 euros.Being a great price and very robust drives I would pick them up but I do not know what H-bridge used to run them.I have already taken the 2dof 2 where I will use the vellemank8055 sabertooth 6 dof but I would use 3 auduino one. What do you recommend?For food no one has tried to put in series two 12 volt power supplies?I know that in theory it can be done but I don't know if there are any contraindications.

    Hi Billo

    Have a look at well known rc forums, they modified some PSUs to put them in series to get 24V. I do not know any bridges with 24V. You can try out the motors running them with 12V, but expect half speed. Perhaps it is enough fast for your motion sim (do not know any specifications of your gear motors).

    Cheers

    @billo2404 : wiring 2 server PSU can be dangerous!
    You cannot simply wire them together:

    you have to remove ground from one and isolate it carefully... I would discourage such electrical mod

    Nice find @RacingMat could be handy for 6DOF units. Cheap too, a decent heatsink and fan sounds like they should kick butt.
