Machine Optimization Through DC Motor Selection

There are so many motors on the market today, from heavy-duty AC motors to tiny DC brushless and stepper motors. To choose a motor, users must have a full understanding of the application parameters, including power, speed, torque, physical size, efficiency, lifetime expectations, and other requirements. There have literally been entire books published about each of these aspects, and to define them all accurately in a short article would be difficult, to say the least.
