    hi all,

    Are there any disadvantages to powering a DC motor using a laptop charger or with any SMPS for that matter?

    What if I use a soft start method ? I'm thinking of powering the motor through a small value power resistor at the start and then bypass the resistor using a relay.

    I will also be using it to power a microcontroller (to control the motor).

    Regards !!!!!!!

    All depends on motor specs.
