When deciding which stepper motor to buy, you should consider the size of your 3D printer. Usually, smaller 3D printers need less torque, meaning a smaller stepper motor will work adequately, while a large 3D printer will need greater torque to move a large print head or bed.
How do I know which stepper motor to use?
A simple way to choose a stepper drive is to look for four things — voltage, current, microstepping, and maximum step pulse rate. Ensure that the drive can handle a wide range of current so that you can test the system at different voltage levels to fit your application.

Are all stepper motors the same?
Two different NEMA 17 motors may have entirely different electrical or mechanical specifications and are not necessarily interchangeable. The next thing to consider is the positioning resolution you require. A 1.8° motor is the same as a 200 step/revolution motor. The trade-off for high resolution is speed and torque.
Why are stepper motors so expensive?
Instead of an armature it has coils arranged around the inside of the stator. Due to the restricted space, the windings on most small in-runners have to be installed by hand. This is a difficult and time-consuming and job, which makes them more expensive than machine wound brushed motors.
How many stepper motors are in a 3D printer?
Most 3D printers utilize NEMA 17 stepper motors. There are many popular variations, each having different physical qualities suitable for different applications. These are primarily distinguished by torque rating, in Newton Centimeters (N⋅cm).
How many stepper motors does a printer have?
There are two stepper motors, one for the printing head to move left and right, on a linear shaft, and one for the paper roll.
What is a stepper motor ender 3?
Motor Model: 42-34 Nema 17, widely work for Most 3D Printer Ender 3 CR-10 CR-10s S5, i3 selece mini, printer etc. High torque -Holding torque up to 0.35Nm. Low loss stators have better high speed performance.
What is NEMA 17 stepper motor?
NEMA 17 stepper motors are those that have a 1.8 degree step angle (200 steps/revolution) with a 1.7 x 1.7 inch faceplate. NEMA 17 steppers typically have more torque than smaller variants, such as NEMA 14 and have a recommended driving voltage of 12-24V. These steppers are also RoHS compliant.
What is NEMA 23 stepper motor?
Nema 23 is a stepper motor with a 2.3 x 2.3 inch faceplate. It is suitable for 3d printer, robot arm, cnc machine,etc. In low-speed applications, the stepper motor can be driven at the desired speed without missing a single step. This stepper motor has different torque, the max torque is 3 Nm.
Why are stepper motors used for 3D printers?
The stepper motors are used for controlling the movement of the axis(all 3) in case of the 3D printer and also for pushing the filament out of the extruding nozzle. The stepper motors are used instead of regular motors as they move in steps and hence control is more and the movement is more precise.
What voltage should a stepper motor run?
Stepper motors have a rated voltage and current. A typical stepper motor like our NEMA 17 might have a rated voltage of 2.8 Volts and a maximum current of 1.68 Amps. This basically means if you hook it up to 2.8 Volts it will draw 1.68 Amps.
Are stepper motors AC or DC?
Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, one step at a time. With a computer controlled stepping you can achieve very precise positioning and/or speed control.
Do stepper motors have high torque?
Stepper motors remain popular for industrial motor applications because they are low-cost, rugged, simple, have high torque at startup and low speeds, require little maintenance, and they can operate in an open loop control system.
What is a 42 stepper motor?
Nema 42 Stepper Motors NEMA 42 stepper motor is the largest step motor of the stepper motor family. This is known to be the finest type of stepping motor. The nema42 stepper motor is mainly used in the applications where precise and efficient motion control is required whether the motion is linear or rotational.
What do stepper motor numbers mean?
The number of steps per revolution ranges from 4 to 400. Commonly available step counts are 24, 48 and 200. Resolution is often expressed as degrees per step. A 1.8° motor is the same as a 200 step/revolution motor. The trade-off for high resolution is speed and torque.
How many wires does a stepper motor have?
While many motors take advantage of 6- and 8-wire configurations, the majority of bipolar (one winding per phase) stepper motors provide four wires to connect to the motor windings.
Which is better stepper motor or DC motor?
The speed range of stepper motors is typically below 2000 RPM, as their torque decreases as speed increases.Table 1: Comparison of brushed motors vs. stepper motors. Characteristics Brushed DC Motors Stepper Motors Torque/speed characteristics High torque at low speeds Maximum torque at low speeds Cost Low Low.
What is the major benefit of a stepper motor?
The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft rotation. Advantages of step motors are low cost, high reliability, high torque at low speeds and a simple, rugged construction that operates in almost any environment.
What is a 12V stepper motor?
The 12V, 1.7A, 416 oz-in Geared Bipolar Stepper Motor has an integrated Planetary gearbox with a 26 103/121 :1 ratio. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler. At 1.7 Amps (maximum current), this stepper motor can produce a maximum torque of 77 kg-cm.
What is the difference between a servo and a stepper motor?
The main difference between these motors comes from the overall pole count. Stepper motors have a high pole count, usually between 50 and 100. Servo motors have a low pole count – between 4 and 12. Servo motors require an encoder to adjust pulses for position control.
What is the difference between full step and half step?
A. In full-step two phases are on and in half-step only one phase is on.
