Stepper Motors
These stepper motors are good for precise, repetitive movements, such as those made by the head of a 3D printer. Similar to the hands of a clock, their shaft turns in small, equal increments. When the shaft stops, it holds its position even when a counteracting force is applied to the load. You can control the position of the load without having to configure encoders or sensors. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.
When relative positioning is critical, such as coordinating motion in a multi-axis system, choose a motor with two shafts and mount an encoder (not included) on one of them. The encoder monitors the position of the shaft and reports back to the controller.
Holding torque is the force needed to move the shaft out of position when it is stationary. When the shaft is in motion, torque generally decreases as speed increases. Use a torque-speed curve to confirm which motor will work for your application. Click on a part number and select “Product Detail” to view the curve for a motor.
All motors require a controller and driver (not included).

Stepper Motors with Integrated Motion Control
With a built-in controller and driver, these stepper motors come ready to program and operate. After connecting to a computer for initial setup, the controller can store and run programs on its own. The controller communicates to the driver which directs the motor’s shaft to move in small, equal increments. When the shaft stops, it holds its position even when a counteracting force is applied to the load. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.
When relative positioning is critical, such as coordinating motion in a multi-axis system, choose a motor with an encoder. The encoder monitors the position of the shaft and reports back to the controller.
Holding torque is the force needed to move the shaft out of position when it is stationary. When the shaft is in motion, torque generally decreases as speed increases. Use a torque-speed curve to confirm which motor will work for your application. Click on a part number and select “Product Detail” to view the curve for a motor.
You can adjust the step resolution down to 1/256 of a full step, which translates to 51,200 microsteps per revolution. Increasing the number of steps directs an even more precise position and reduces the step-step-step motion to mimic a smooth, continuous rotation. The higher the number of step resolution settings, the greater the flexibility you have for determining the size of the motor’s step.

This means you don’t need to configure encoders or sensors to control the position of the load.

Compact Stepper Motor Actuators
A lead screw that converts rotational motion to linear motion sits inside the motor body for a compact footprint. Add a driver and controller to these actuators to repeatedly position loads with speed and precision. Moving in small, equal steps, these actuators are good for jobs requiring fine motion control, such as positioning electrical components on a circuit board. Their load stays in position even when a counteracting force is applied, so you don’t need encoders, sensors, or other position feedback devices.
All have bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors. The splined shaft keeps the rod from rotating as it extends and retracts.
Travel distance per full step determines the control you have over the actuator's positioning. The smaller the measurement, the finer positioning control you have, but the more steps it will take to go the same distance.
Dynamic load capacity is the maximum load an actuator can move. If you increase the speed, the dynamic load capacity decreases. Click on a part number and select "Product Detail" to view the load-speed chart and confirm the actuator will work for your application.
