Servo motor systems are expensive but great for demanding applications that require high speed, peak torque, or feedback. Stepper motors are cost-effective but do not offer the peace of mind of feedback. For designs that do not need the bells and whistles of servo motor systems, there is another option.

The best motor is the one that meets the application requirements. However, when both servo motors and stepper motors satisfy the basic requirements of a positioning application, it's important to have a deeper understanding of the two technologies to make an informed decision.
In this blog post, we will summarize the differences between servo motor systems and stepper motor systems.

Knowing how to use a product properly can make a huge difference in its performance and life. For example, knowing how to maintain cast iron pans properly can make them last longer. With electric motors, understanding the factors that affect motor life is the first step to extending life and decreasing costs in the long run.

For someone who has never had experience wiring I/O for motion control, it can be scary the first time. If devices are not wired correctly, it can cause a range of issues from a motor simply not doing what's expected to irreversible product damage. I still get that nervous feeling before I press the START button on a demo. Murphy's Law, anyone?

The significance of position control accuracy of motors varies depending on the application. For an AGV in a farm with DC motor-driven wheels, position control accuracy is probably not as crucial as a surgical robot where incisions are controlled by servo motors or stepper motors.

Besides load torque, acceleration torque, speed, and load inertia, overlooking certain sizing parameters during the motor sizing process can literally make or break your machine.

Now that we understand the calculations behind load torque and load inertia, we're a little closer to motor selection. You might be wondering why I separated load torque and acceleration torque calculations. That's because in order to calculate for acceleration torque, load inertia and speed must be calculated first.
