    I need to make a power supply for a motor for my project.
    Mains Voltage is 240V AC,13A at 50Hz
    I need 24V DC for the motor and motor current rating is ard 1.7 to 2.3A.
    I am not sure what are the parts i need and what calculations i need to perform.

    If you could find the right power supply, you could scavenge one from an old computer. By "right", I mean one that could handle the current you need on its -12V supply. Any psu will have more than enough current for you at +12V, but obviously to get 24V, you'll need to use both the +12 and the -12 to get your 24V. Many or most psu don't handle over 2A on the -12V, but it sure would be an easy solution if you can find one.

    First you need to perform: is it AC or DC that the motor needs?
    AC only requires a transformer. DC requires a transformer, rectifier, filter capacitor, and MAYBE a regulator. If the motor isn't too picky, and some of them aren't, you won't need a regulator.

    The motor requires fixed 24V dc.
    I think i need a step down transformer,bridge rectifier,smoothing capacitor and a regulator.
    I dunno what power rating i require for the transformer.And whether i must put a fuse.how to calculate the value for smoothing capacitor.

    Thanking you,
