Housed in a durable steel enclosure, these controls convert AC input voltage into DC output voltage and control the speed of permanent-magnet DC motors.

A heat sink (sold separately) is required with outputs greater than 5 amps.

Vary the speed of three-phase AC motors. Mount these controls inside a machine or control cabinet. They’re often used in packaging machines, conveyors, and vacuum equipment. Operate controls manually or remotely with an electrical signal.

Input adapters (sold separately) allow controls to accept a range of input voltages and current. Mount to the bottom of the control.

Control the speed of low-voltage permanent-magnet DC motors. These controls accept DC input voltage and supply a variable DC output voltage. Set a minimum and maximum speed and adjust the current limit on these controls. Operate controls manually or remotely with an electrical signal.

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.

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.
