hi there ,
As per your query ,
The performance of a DC motor is given by the relation among the armature current, torque and speed . These relations are given graphically in the form of curves, which are called as characteristics of DC motors. These characteristics show the behaviour of the DC motor under different load conditions.
Hope you understand , in case of any query you can comment here and also make a new query for the same.
Thank you and all the best.
