    Re: 775 dc motor 18v

    I guess Ebay is as good as place as any.
    Maybe something this one?

    https://www.ebay.co.uk/itm/FARNELL-N....c100005.m1851

    Not sure what the Max current output is. It has to be HIGHER than what you need, ie ~15 Amps.
    Research it or ask the seller what its rating is.

    Other than that you could get a Switch Mode Power Supply cheap of Ebay. They are cheap, small, efficient but alot more complicated. Some have to have a load connected before they will turn on......

    A 24V battery charger will work if it can supply enough current.

    A local second hand shop or junk yard may have something?

    Radiospares or Farrnel ( They won't be cheap....lol)


    If you go this route, you will only have FULL SPEED unless to also use a PWM DC Motor Speed Control. ( cheap on Ebay ) and you wil ahve to turn the spindle on and adjust the speed manually...not a big deal....



    There's a few options.

    Re: 775 dc motor 18v

    thanks for the suggestions I'm not too bothered if the motor is running at full speed, and was wondering if you could tell me if this could be used on the link below

    thanks again

    *Maybe*.....Its a bit of a crap shoot. I may have misled you regarding SMPS's. I can't say for sure without a benchtest and that would not be easy to arrange.
    See:

    I agree with Al.....a simple linear power supply would be the best solution. Any simple DC power supply would be less of a risk than a complicated Switch Mode PS. Rugged and easy to fix.
