Choosing between a servo motor and a stepper motor can be quite challenging. The selection of a correct motor for the application involves several parameters.
In this post, we are going to discuss what is the difference between servo motor and stepper motor.
About Motors
Automation is like a new era of automobile industry which is spreading like wildfire across the world. Everyone is looking to accelerate production in an effective and efficient manner. But to accelerate production, each unit assembled in the industry must operate with its full efficiency. And to do this, a project manager like you should take care when choosing parts for a particular unit. If you will choose a part for your plant, then you have to check its pro and cons and you will also have to check its capabilities. So in this section, I am telling you about the pros and cons of servo motor and stepper motor which will help you in the selection of these motors.
Servo Motor Vs Stepper Motor
The main difference between the stepper motor and the servo motor is a pole count. The servo motor has a less number of poles than the stepper motor. Whereas the stepper motor has more poles than the servo.
What Is Stepper Motor?
A motor that runs in discrete steps after powering is called a stepper motor. These motors do not have an encoder inbuilt. But if it is needed it can be added externally.
As the encoder in the stepper motor is not present, the stepper motor is less complex than the servo motor. And as the total pole count is higher, the stepper motor produces higher torque than the servo motor.
The main drawback of stepper motors is that they cannot produce the same torque at high speeds. They miss phases and that is why they are not preferred for applications where high speed is a priority.
What Is Servo Motor?
The servo motor has an encoder inbuilt that monitors the shaft movement because this type of motor has an encoder inbuilt, this motor gives high accuracy at high speeds.
The servo motors are pulsed in the standstill position and this is why they cannot be used in applications where the stability of the motor is higher than the subject.
If you want to know more about the work of servo motor, I request you to check this blog. A friend of mine has explained everything about servo motor in it and I am sure it will help you.
Torque of the Motors
Both the servo motor and the stepper motor produce the same amount of torque. You will generally get higher performance from a servo motor with a more flexible speed curve and an additional time-dependent peak torque rating, but again, an optimized stepper motor can usually do the same job in a more economical way.

Heating Issue In Motor
Stepper motor generates a lot more heat than a servo motor. Therefore stepper motors should not be used in an application where the temperature is a concern.
Conclusion
