AC to DC Motor Speed Controls

Convert AC input voltage into DC output voltage and control the speed of permanent-magnet DC motors.

Reversing Enclosed AC to DC Motor Speed Controls

Use these controls with motors that run forward and backward, such as motors for conveyor belts.

Enclosed AC to DC Motor Speed Controls

Reversing Washdown Enclosed
AC to DC Motor Speed Controls

Use these controls with motors that run forward and backward, such as motors for conveyor belts.

Washdown Enclosed AC to DC Motor Speed Controls

A NEMA 4X rated enclosure protects these controls from corrosion and washdowns.

Three-Phase AC Motor Speed Controls

Programmable Three-Phase AC Motor Speed Controls

Set these controls to automatically adjust motor speed.

Washdown Programmable
Three-Phase AC Motor Speed Controls

Rated NEMA 4, these controls are protected from washdowns.

DIN-Rail Mount Programmable
Three-Phase AC Motor Speed Controls

Mount these controls to DIN rail inside a control panel.

Three-Phase AC Motor Speed Controls

Manually control a motor's speed.

Low-Voltage DC Motor Speed Controls

Control the speed of low-voltage permanent-magnet DC motors.

Electric-Powered Motion and Control

Stepper Motor Controllers and Drivers

Tell your stepper motor how far and fast to go by adding a controller and driver to your system.

Stepper Motors

These stepper motors are good for precise, repetitive movements, such as those made by the head of a 3D printer.

Stepper Motors with Integrated Motion Control

With a built-in controller and driver, these stepper motors come ready to program and operate.

Wet-Location Stepper Motors

To precisely position loads in automated systems that are frequently rinsed, these stepper motors are IP65 rated to seal out water.

Stepper Motors with Linear Actuation

Instead of a shaft, these stepper motors have a lead screw that converts rotational motion to linear motion.

Speed-Control Motors

Maintain speed automatically. These motors come with a speed control with a feedback sensor that adjusts power to maintain your set speed.

Compact Stepper Motor Actuators

A lead screw that converts rotational motion to linear motion sits inside the motor body for a compact footprint. Add a driver and controller to these actuators to repeatedly position loads with speed and precision.
