    How to calculate torque of a dc motor.

    I have got a dc motor with imprint:

    I can vary its speed, direction & control barke with a drive along with it, but don't know exactly how to calculate torque. It will be different with speed??

    A DC motor will have a specified "Torque Constant", usually written as K_sub_T. Torque is then given as K_sub_T*Current. The specifications should also have a set of "Speed-Torque" curves that show the decline of torque with increasing speed. You need to find that datasheet.
