Why Does My Stepper Motor Get Hot?
All electric motors heat up during operation, which is simply a product of passing current through a coil of wire. Electric motors use copper wire to form coils that are part of the electromagnetic circuit required to produce rotation. While copper is a very good conductor, it does have resistance that causes the copper to heat up. The amount of current delivered to the motor along with the winding resistance determines how hot it gets. The nature of stepper motor operation requires full rated current to be applied at all times, which differs from a servo motor that provides only the required current to produce the desired motion.

What You Need to Know When Selecting a Drive for Your Stepper Motor
To get the most out of your stepper motor, you need to pair it with the proper drive. There are three critical elements to keep in mind when making your selection: voltage, current and inductance. Each one plays an important part in a motor’s performance, and not accounting for these parameters can lead to poor performance or even cause the motor to overheat and fail—resulting in lost production time and increased maintenance costs.
The Big Debate – Stepper vs Servo
What is the best motor technology to use in a motion control application? There are numerous technologies to create motion, from hydraulic to pneumatic or electromechanical. In the world of precision motion control, many machine designers face a choice between step motor or servo motor technologies to solve their performance requirements. Both stepper motors and servo motors have a place in the motion control world but understanding when to use each has created a big debate
