Mar 09, 2017018332Understanding the torque equation and the relationship between speed and torque is an important part of selecting and operating a DC motor.. DC motors are relatively simple machines when the load on the motor is constant, speed is proportional to supply voltage. And when supply voltage is constant, speed is inversely proportional to the load on the motor.

In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study.The concept originated with the studies by Archimedes of the usage of levers.Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis.
