    Stepper Motor Buying Guide

    Stepper motor is one of many motors. Although it is the same as other motors in terms of functional types, it is different from other types of motors in terms of working principle and structural design. The operation form, functional performance, applicable aspects and performance of different stepping motors are different from other types of motors.

    The buying of stepper motors is very complicated. Next, we will introduce 2-phase and 3-phase stepper motors as well as micro stepper motors and linear stepper motors. Allows you to make better choices in your purchases.

    How to choose a 2-phase or 3-phase stepper motor when buying

    The number of phases of the motor refers to the number of coils inside the motor. The 2-phase stepper motor is composed of 2 coils, while the 3-phase stepper motor is composed of 3 coils.

    The torque of a 2-phase motor with the same size will be slightly larger than that of a 3-phase motor. The subdivision function of the 2-phase stepper motor driver is becoming more and more powerful, and the 2-phase can also achieve the accuracy that the 3-phase can achieve.

    Nema 17 stepper motor 2 phase

    Nema 17 stepper motorThe Nema 17 stepper motor is a type of 2-phase stepper motor, Nema 17 means its size is 1.7x1.7 inches. This means that generally the larger the torque model, the more torque the machine can twist.

    Its advantage is that it can rotate synchronously at very low speed just by directly connecting the load to the shaft of the motor. Since the speed is proportional to the pulse frequency, the Nema 17 stepper motor has a relatively wide speed range.

    Depending on the required current or torque, we can provide you with different stepper motors. If you need a larger motor of the same model, we also have Nema 24 stepper motors on sale for you to choose and purchase.

    Nema 23 stepper motor 2 phase closed loop

    Nema 23 closed loop stepper motorThe advantage of the closed-loop Nema 23 stepper motor is that it greatly enhances the high-speed performance of the motor. The effective torque of the motor can be increased by more than 30%. Effectively reduce the heat generated by the motor. The driver output current increases with the load and speed, and decreases with the decrease. If you acquire this product, it will definitely bring great convenience to your work.

    We also distinguish the same type of stepper motors according to the magnitude of the current. If you are interested in a larger closed-loop stepper motor, we also have a closed-loop Nema34 stepper motor for you to buy.

    Nema 42 stepper motor 3 phase

    Nema 42 stepper motorThe 3-phase stepping motor has good high-speed performance (harder characteristics), and has a smaller step angle and better accuracy than the two-phase stepping motor. Since the torque decreases slowly with the increase of speed, it is usually used in occasions where high precision is required.

    This 3-phase Nema 42 stepper motor is characterized by the accuracy of each step of 3% to 5%, and will not accumulate the error of one step to the next step. Therefore, the Nema 42 stepper motor has better position accuracy and motion repetition ability. If you want to know more about it, you can click on Nema 42 stepper motor to buy.

    Micro stepper motor 2 phase

    Micro stepper motorMicro stepper motor is a special type of motor used to accurately control position and speed. Because the stepper motor has low operating cost and the driver is not easy to damage, it is very suitable for microcomputer and single-chip control, and is widely used in all walks of life. Micro stepper motors can achieve higher resolution or smoother motion at low speeds. The micro stepping motor controls the angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning; it can also control the speed and acceleration of the motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation.

    We also have different models of micro stepper motors on sale for you to choose from.

    Linear stepper motor 2 phase

    Stepper motor inearThe linear stepping motor is rotated by the magnetic rotor iron core through the interaction with the pulsed electromagnetic field generated by the stator. The linear stepping motor converts the rotary motion into linear motion inside the motor.

    One of the advantages of linear stepping motors is high-speed responsiveness. Generally speaking, the dynamic response time of mechanical transmission parts is several orders of magnitude larger than that of electrical components. Because some mechanical transmission parts such as lead screws with large response time constants are eliminated in the system, the dynamic response performance of the entire closed-loop control system is greatly improved, and the response is extremely sensitive and fast. The size and current of the linear stepper motor will also achieve different effects. More information on linear stepper motors can be found on our purchase page.

    Overall, stepper motors are a very useful and easy-to-use device. It also has many types and functions. Different currents, models, torques, etc. will have different effects. If you want to know more, you can go to ATO website to find more relevant information.
