Stepper Motor Controllers and Drivers

Tell your stepper motor how far and fast to go by adding a controller and driver to your system. A controller is similar to a PLC—they store and run programs and send signals to a driver. These controllers have commands specifically for stepper motors such as number of steps and direction. The driver delivers power to the motor based on the signals from the controller. Choose from individual controllers and drivers or a combination controller/driver.

Drivers

Driver

Drivers can be set to different step resolutions. The higher the number of step resolution settings, the greater the flexibility you have for determining the size of the motor’s step.

Choose a driver rated at or below your motor's maximum current.

Step resolution determines the size of the step a motor takes. For example, setting a 1/128 step resolution on your driver divides one full step into 128 smaller steps. The smaller the steps your motor takes the more smoothly and precisely it will move.

Controller/Drivers

Controller/Driver

Simplify setup with these single units. The controller and driver are combined, so you can determine all your settings from one device including number of steps, direction, and step resolution. They have multiple inputs and outputs to communicate with more than just a motor. Connect sensors and switches or link multiple controllers together to coordinate movements between motors.

Choose a controller/driver rated at or below your motor’s maximum current.

Encoder-compatible controller/drivers are best when relative positioning is critical, such as coordinating motion in a multi-axis system. They connect to an encoder (not included), which monitors the position of the motor's shaft and reports back to the controller.

Step resolution determines the size of the step a motor takes. For example, setting a 1/128 step resolution on your controller/driver divides one full step into 128 smaller steps. The smaller the steps your motor takes the more smoothly and precisely it will move.

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.
