How are DC motors controlled?
The characteristics of a DC motor are represented by its torque-speed curve, in which speed and load torque are inversely proportional. This torque-speed curve translates with changes in drive voltage. Accordingly, by adjusting the voltage applied to a DC motor, it can be made to run at any speed regardless of load torque.

Understanding Torque Curves: A Comprehensive Guide
At the heart of a torque curve is the relationship between torque and engine speed, measured in revolutions per minute (RPM). Torque is a measure of rotational force, expressed in Newton-meters (N-m) or pound-feet (lb-ft), while engine speed represents the rate at which the engine rotates. The torque curve typically plots torque …
