Difference between Stepper Motor and Servo Motor

Selecting the right motor for different applications depends on some design criteria such as positional accuracy requirements, cost, availability of drive power, torque and acceleration requirements. Overall, the motors like DC, servo, and stepper motors are best for different applications. But, the stepper motor is well suited for high holding torque and lower acceleration applications. Many are under the misunderstanding that there is a huge difference between DC motor, servo motor, and stepper motor. To know the differences between these three motors, this article gives a brief difference between these three motors. Selecting between a DC motor, a Servo Motor, and a Stepper Motor can be quite a task, including the balancing of numerous design factors, namely cost, speed, torque, acceleration, and also drive circuitry all play an essential role in choosing the best electric motor for your application. DC Motor is a two wire continuous rotation motor and the two wires are power and ground.

Choosing the right motor is critical for the efficiency and productivity of your motion control applications. It can be difficult to choose between servo motors and stepper motors as there are so many considerations: cost, torque, efficiency, speed, circuitry and more. It helps to first understand what differentiates these motors and the particular pros and cons each provides. You can then align the capabilities of the motor with the needs of your application. The main difference between these motors comes from the overall pole count.

From security cameras and fans, to DVD players and right down to the vibration in your phone, motors are practically all around us. With so many variables to consider, it is hardly surprising that many find it difficult to choose the right motor for their application and miss out certain important parameters in the process. As such, we have put together a guide to help you with the selection process, so that you may pick the best motor for your application. We will be looking at 3 common motors — the DC, Stepper, and Servo motors, their applications, as well as their advantages and disadvantages. DC motors are electromagnetic devices that use the interaction of magnetic fields and conductors to convert electrical energy to mechanical energy for rotation. There are many types of DC motors out in the market.

A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors. Servomotors are not a specific class of motor, although the term servomotor is often used to refer to a motor suitable for use in a closed-loop control system. Servomotors are used in applications such as robotics , CNC machinery or automated manufacturing. A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position.

Do you need stepper motors or servo motors in your business? Perhaps you need both. Although they are not as different as some might think, there are some significant differences between the two.

This tutorial will help you understand the differences between stepper and servo motors, and how to select the best motor for your application. We will cover motor basics including construction, current, functions and features, questions to ask when selecting a motor, application examples, key terminology, and more. We also provide additional resources for more information. Most industrial stepper motors are hybrid stepper motors that consist of a permanent magnet rotor and a wound electromagnetic stator. The current supplied from the drive creates a magnetic field that is used rotate the shaft of the motor.

To control stepper motor, we need an external control circuit or micro controller e. The closed-loop configuration that Servo Motors offer allows the motor to generate faster speeds and up to three times the torque than their Stepper counterparts.
