    Hi engineers.

    I want to run 2 12volt dc motors .

    Please suggest me simple solution and components needed.

    I have 12-0-12 transformer.


    Thanks in advance.

    make a dc psu with a couple of diodes or a bridge rectifier,smoothing caps, voltage regulator or two, then how do you want to control the motors?

    Presumably your transformer is rated to supply enough current for both motors running at the same time, and is able to withstand start-up surge currents?

    You most likely do not need anything but simply two rectifiers rated for the motors, as long as the transformer will handle the current for both.
    The 0v will be common for both 12v outputs with a rectifier on each.
    Do you intend controlling rpm?

    Transformer an two rectifiers rating depending on you motor current.
    The diagram shows the secondary top to bottom, 12v-0-12v.
