DC motors are motion components that take electrical power in the form of direct current (or some manipulated form of direct current) and convert it into mechanical rotation. The motors do this through the use of magnetic fields that arise from the electric currents to spur rotation of a rotor fixed with an output shaft. Output torque and speed depends on the electrical input and motor design.
In this Design Guide, the editors of Design World detail the most common dc motor types as well common ways to quantify their output during the design-engineering process.
