The performance of a d.c. motor can be judged from its characteristic curves known as motor characteristics, following are the three important characteristics of a d.c. motor: It is the curve between armature torque Ta and armature current Ia of a d.c. motor. It is also known as electrical characteristic of the motor.
In order to effectively design with D.C. motors, it is necessary to understand their characteristic curves. For every motor, there is a specific Torque/Speed curve and Power curve. The graph above shows a torque/speed curve of a typical D.C. motor. Note that torque is inversely proportioal to the speed of the output shaft.
As for a generator (See Sec. 1.29), the efficiency of a d.c. motor will be maximum when: Variable losses = Constant losses Therefore, the efficiency curve of a d.c. motor is similar in shape to that of a d.c. generator.

For every motor, there is a specific Torque/Speed curve and Power curve. The graph above shows a torque/speed curve of a typical D.C. motor. Note that torque is inversely proportioal to the speed of the output shaft. In other words, there is a tradeoff between how much torque a motor delivers, and how fast the output shaft spins.
The dynamic behavior of DC motor can be described using two equations. The load also reflects the moment of static friction inherent in the system. For a better interpretation of the equations (1) and (2) an energy consideration is now per-formed. Given by the equation (1) is multiplied with the current i and integrated over an indefinite interval.
Due to decreased Eb, more armature current is allowed. This characteristic is also called as mechanical characteristic. From the above two characteristics of DC series motor, it can be found that when speed is high, torque is low and vice versa. In case of DC shunt motors, we can assume the field flux ɸ to be constant.
