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.
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.
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.

To improve positioning accuracy, these stepper motors have a built-in encoder that monitors the real-time speed and position of the shaft.

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.

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.

DC Servomotors with Integrated Drive
A built-in drive simplifies your servomotor setup, removing the need for cable between the motor and drive. DC servomotors are often used for small automation applications, such as pick-and-place machines, because they deliver lots of power in a small package. This system includes a motor, encoder, and drive for accurate positioning and fine control over speed and position.
These servomotors use the same step and direction commands as a stepper motor, so you can upgrade your current stepper motor system with this system. 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. 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.
Power supplies are designed to power servomotors, so they have tightly controlled voltage and high peak current output to support high performance motor control. They are capable of handling or dissipating regenerated energy as the motor slows or stops.

Stepper Servomotors
Combine the high torque at low speeds that traditional stepper motors are known for with the greater torque performance and positioning reliability of a servomotor. They create rotary motion based on signals from a drive (sold separately). As these servomotors move, their encoder relays the shaft’s distance, direction, and speed back to the drive. The drive increases your system’s efficiency by taking the electrical signal from the encoder and dynamically adapting the motor’s movements, also accounting for inconsistent loads and unexpected forces.
Drives have several control modes that power the motor—sequencing, position, speed, or torque. You can program target positions with speeds and accelerations in the drive to trigger sequences with minimal input from a controller. You can also use a computer, programmable logic controller (PLC), microcontroller, or indexer to set motion parameters, tune the motor to your mechanical system, and stream multiple commands to the driver to carry out complex motion sequences.
