    good I want to buy a power supply for my simulator 2dof, motors are smolka 24v which source you advise me and amperage.

    Thank you

    [QUOTE = "noorbeast, post: 174939, miembro: 10786"] Las PSU LED deberían funcionar bien: https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=led+24v+power + supply & _sacat = 0 & LH_TitleDesc = 0 & _osacat = 0 & _odkw = meanwell + 24v + power + supply & LH_TitleDesc = 0

    Personalmente uso un PSU por motor, ya que nuestros equipos crean picos con inversiones rápidas.

    No tengo idea de lo que dibujan los motores, por lo que tendré una puñalada salvaje en las PSU de 20amp 480w. [/ QUOTE]
    I what happens that the 2dof I have it with pololu 5019 and the 3dof I have it with 3 ibt-2. Pololu only has one input to power both motors. which one do you advise me

    Hello
    For me the solution to the psu not dedicated to inductive loads was to mount a large leveling capacitor at the ends of the power supply.
    it is a condenser for car audio use of 0.5 / 1 F, in the case of 24V unfortunately they need 2 in series.
    thanks to their large reserve of energy and low internal resistance, they are able to block all inductive returns and a large current input. in my case I use 2 engines from power steering of opel corsa 16: 1 with 30x atx power supply so amazing!
    deep hello
    Marco

    I have 2 sources of 24v that are 15A can be worth me if I connect them in series or I will have some problem thank you very much

    if I put in series two sources of 24v and 15A that output daria 48v and 30A I ask if there is anybody who can help me out thanks

    [QUOTE = "tmp, post: 174936, miembro: 32759"] bien, quiero comprar una fuente de alimentación para mi simulador 2dof, los motores son smolka 24v, qué fuente me avisa y amperaje.

    have if you can make me a hand some colleagues that I fear will not go to burn the plate.

    Thank you

    good I have the simulator of 2dof with pololu 5019 and another 3dof with ibt-2.
    my question which power source you advise me for each one of them please I am sticky on that subject thank you.

    hello TMP
    if you mean two capacitors in series, you can do it.
    usually they are capacitors that support up to 17V each.
    the capacity remains unchanged, while the supported voltage doubles.
    however, the internal resistance is halved, losing effectiveness, even if it remains acceptable with good capacitors

    Different power supply will be unstable when used together. Generally, it is not recommended to do so. If you really want to do so, you need to use the same power supply. I usually use second-hand communication power supply module, which is small in size and cost-effective. The old server power supply is also good

    I have the same motors as you on my 2DOF simulator, I use a 24V / 20A power supply and 2 batteries of 12V / 7Ah in series to absorb the current returns and not to restrict the motors at the starting.

    By the way, I recorded the current and voltage consumed by the 2 smolka motors with a Hioki datalogger and a precision shunt (One measurement every 20ms).

    Here are the results with the power supply alone:

    And now with 2 12V batteries in parallel with the power supply:
    avecbatterie.jpg

    It can be seen that the batteries allow the voltage to be smoothed out, and do not restrict the current during the starting phase of the motors.
