    DC motor, Arduino
    So I've recently made a diy ffb wheel using a broken Trustmaster tx wheel with a stm32f407vet6 board with vnm wheelbase firmware, 1000 p/r omron encoder, I've swapped the servo motor for a dc rs 775 motor, the motor has some insane specs with a stall current of 156A and 1.3Nm of torque, I'm obviously not aiming for that but i already have two identical switching 12v 20a psu's so i was wondering if i got two bts motor drivers and powered them both separately and then outputted them both to the dc motor would the motor be at 24v or would it just be a big bang? I've done a very simple drawing in paint to illustrate what i mean.

    That's not how electricity works. Two power sources in parallel will increase the maximum current, not the voltage.
    Both of them in series will increase the voltage.
    You can put the power supplies in parallel to get more current, but I doubt that you can put two of your motor controllers in parallel. You need a bigger motor controller.

    Caution! You CANNOT put your power supplies in series, this will kill one or both of your supplies! There are exceptions, but I do not recommend this path for you.
