    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.
    All motors require a controller and drive (not included).
    8 Wire Leads—Motors with 8 wire leads can be connected to a drive 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.
    2 Shafts—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.
    Maximum Holding Torque—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—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 size and complexity of your stepper motor setup—these motors have a drive built in, so you don’t need to run cable to a standalone drive. The drive 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.
    Maximum Holding Torque—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—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.
    Step Resolution—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.

    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.

    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.
    All motors require a controller and driver (not included).

After that, the controller can store and run programs on its own. The controller communicates to the drive 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.
    Encoders—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.
    Maximum Holding Torque—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—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.
    Step Resolution—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.

    Wet-Environment Stepper Motors

    To precisely position loads in automated systems that are frequently rinsed, these stepper motors are IP65 rated to seal out water. Their shaft turns in small, equal increments, similar to the hands of a clock. When the shaft stops, it holds its position even when force is applied to the load. This means you don’t need to configure encoders or sensors to control the position of the load. All are hybrid bipolar stepper motors, so they have more torque, precision, and efficiency than other stepper motors.
    These stepper motors require a controller and drive (not included).

    Stepper Servomotors with Integrated Drive

    Image of Product. Front orientation. Servomotors. 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.
    Maximum Holding Torque—Holding torque is the force needed to move the shaft out of position when it is stationary. 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.

    High-Temperature Stepper Motors

    The widest temperature range of any stepper motor we offer—these motors were designed with grease and magnets that are particularly good for temperatures up to 212° F. They also work well in low temperatures down to -40° F. 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, sensors, or other position feedback devices. 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.
    All motors require a controller and drive (not included).

    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. You can control the position of the load without having to configure encoders, sensors, or other position feedback devices. 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.
