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, so the current can flow in both directions. This helps them deliver higher torque, precision, and efficiency than unipolar stepper motors.
Motors with 8 wire leads can be connected to a driver in two different ways, so you can choose between more speed or more torque. Depending on your application, you could configure the motor for high torque at low speeds or for low torque at high speeds.
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.
Full step increment is the rotation of the shaft from one position to the next. A smaller full step increment means the rotor has more teeth, producing smoother and more precise motion. 1.8° is considered standard.
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. Connect them to a computer and use the free downloadable software to set them up. After that, 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.

Stepper Gearmotors
A stepper motor and gearbox in one, choose these motors when you want high torque but don’t have space for a large motor. Their planetary gearbox efficiently transmits power to increase torque while reducing speed. These motors are great for motion similar to a 3D printer head, using precise, repetitive movements. Like the hands of a clock, their shaft turns in small, equal increments. When the shaft stops, it holds its position, even if there’s a counteracting force on the load. You can control the position of the load without configuring encoders or sensors. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.
Holding torque is the force needed to move the shaft out of position when it’s 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.
Full step increment is the rotation of the shaft from one position to the next. The smaller the increment, the smoother and more precise the motion.
All motors require a controller and driver (not included).

Stepper Motors with Driver
Reduce the size and complexity of your stepper motor setup—these motors have a driver built in, so you don’t need to run cable to a standalone driver. The driver delivers power to the motor based on signals from a PLC, pulse generator, or other controller. These 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 for smooth motion. 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, so the current can flow in both directions. This helps them deliver higher torque, precision, and efficiency than unipolar stepper motors.
Holding torque is the force needed to move the shaft out of position when it’s 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.
Full step increment is the rotation of the shaft from one position to the next. A smaller full step increment means the rotor has more teeth, producing smoother and more precise motion. 1.8° is considered standard.
Reduce the step resolution to break a full step into smaller steps for smoother motion. For example, setting a 1/256 step resolution on your driver divides one full step into 256 smaller steps.

Stepper Motors with Encoder
To improve positioning accuracy, these stepper motors have a built-in encoder that monitors the real-time speed and position of the shaft. It sends that data to a controller (not included), which adjusts or stops the shaft if it isn’t in the right place. This makes them useful when relative positioning is critical, such as when coordinating motion between two motors. Stepper motors are good for precise, repetitive movements. Similar to the hands of a clock, their shaft turns in small, equal increments for smooth motion. When the shaft stops, it holds its position even when a counteracting force is applied to the load.

Clean Room Stepper Motors
Deliver precise, repeatable motion in applications where contamination is a concern, such as semiconductor manufacturing. These motors meet the strictest clean room standards—all components are cleaned and assembled in a clean room and stored in vacuum sealed packaging. Made of treated aluminum, they minimize gas and particle emission in your clean room’s environment. They're often used in vacuum chambers, where low particle emission prevents the vacuum from degrading. Similar to the hands of a clock, the shaft on these stepper motors turns in small, equal increments for smooth motion. When the shaft stops, it holds its position even when a counteracting force is applied to the load.

Stepper Servomotors with Integrated Drive
Simplify your servomotor setup—these servomotors have a built-in drive, removing the need for cable between the motor and drive. They create high torque at low speeds like traditional stepper motors but with greater torque performance and positioning reliability.
These servomotors accept step and direction, position, speed, torque, or sequencing commands. Use a computer to set up and calibrate the motor to your system. After initial setup, use a separate controller, such as a programmable logic controller (PLC), microcontroller, or indexer. You can also store target positions with speeds and accelerations in the drive and then trigger each sequence with minimal input from a controller. The encoder relays distance, direction, and speed back to the servomotor. Based on this feedback, the servomotor dynamically adapts its movements to increase system efficiency.
Holding torque is the force needed to move the shaft out of position when it is stationary. Torque generally decreases as speed increases.
