Brushless DC Motor Controllers
Servo Motor? Hub Motor? Inrunner or Outrunner? From a few Watts to 30kW, if your motor has permanent magnets and has 3 power wires, Roboteq has one or more controllers that will make it turn. Regardless of your motor’s size or channel configuration, just match the voltage and current rating using our Product Tables below, or use the Roboteq Product Finder.
Roboteq drives have the feature sets that make them well suited in a wide range of advanced motion control applications: precise speed, torque, and position control; exceptional power density, dual‑channel, battery operation support, regenerative braking, fieldbus connectivity, rugged construction, Functional Safety (STO), and advanced protection are some of the enabling technologies found in our RoboG4 drives.
4th Generation Processor Architecture
Helping Make Your Robot Mobile...
Mobile Robots need two motors to move and steer. Only Roboteq can make this work with a single controller. Compared to the traditional One Motor/One Controller approach, the Dual Channel is simpler, cheaper, and easier to integrate and maintain.
Motors are coordinated within the controller, resulting in superior and safer drive characteristics.
...or Make it Move in Every Direction
Two controllers can even team up to drive 4 motors with Mecanum wheels to move Omnidirectional Robots. We can show you how.
Part of Roboteq's Integrated Solution for AGV’s
Add Roboteq’s Magnetic Guide Sensor and you have a fully functional, line following Automatic Guided Vehicle with just two components.
Make it even better with our Battery Management System for Lithium Batteries. You can add our Robot IO eXtender Module (RIOX) with its inertial measurement unit (IMU) for extra stability. Use matching motor/wheel assemblies from our Validated Motor Partners. Download Magnetic Navigation Software and get free, Expert Support from Roboteq to make it all work for you.
Interface with Anything
Our controllers can be operated from practically anything. From simple push buttons, to Joysticks, Radios, PLCs, or Computers, Roboteq can interface with it. A generous number of Pulse/Analog/Digital Inputs are available for limit switches, potentiometers, encoders, buttons or sensors. Digital Outputs provide for braking, lights, or solenoids. Need more IO? Use our RIOX IO eXtender via CANbus and know no limits!
Enjoy the Silence and Efficiency of Sine
Brushless motor controllers work by creating a rotating magnetic field inside the motor’s coils. The rotor’s magnets then follow to cause rotation. In addition to the common, coarse, 6-step Trapezoidal rotation, Roboteq’s controllers are capable of the more refined and quieter running 512-step Sinusoidal rotation. Thanks to advanced Field Oriented Control (FOC), the motor is always operating at optimal efficiency.
All Rotor Sensor Types – Even no sensor
Knowing the Rotor’s position in real-time is essential for making it turn smoothly and efficiently. We support practically all known rotor sensor types from the most common to the most accurate. No sensor? No problem! We also support sensorless operation.
and - if - loop - goto - next
These are some of the keywords all our controllers understand thanks to their built-in MicroBasic programming language. Think of it as having a PLC built right into the controller, at no extra charge. This Roboteq exclusive feature will let you tailor the controller to match your most exotic requirements.
Yes, We CAN!
All our controllers have a 1Mbit CANbus interface. Using a simple wire pair, you can make two or more controllers work together, connect to Joysticks, PLCs, Battery Management Systems, or any other smart sensor. And thanks to four different available CAN protocols, you can be sure that they will be able to understand each other.
Safe and Always Ready for the Unexpected
Much of the functionality of Roboteq's controllers is never used. However, that unused functionality is there because we all know that eventually “what can go wrong, will go wrong”. From excessive amps to over/under voltage, short-circuits to feedback breakdown, the unexpected is no match for Roboteq's Brushless DC Motor Controller!
In mobile robots applications, "Stop" must always mean stop. And "Always" really means always - even if the motor controller is faulty and unresponsive. To do this, a growing number of our controller implement the STO - Safe Torque Off capability.

So Many Operating Modes, So Little Time
Go to and maintain the speed you need, at the acceleration you want. Move forward or reverse with controlled torque. Stop exactly where you need. Consume or regenerate energy. With a fast 1ms Loop Update rate, five main Operating Modes and numerous configurable settings, our controllers will make your motor run as accurately, smoothly and responsively as required by your application.
Never Loses its Cool
High power at low voltage means high current. High current means heat. And excessive heat means trouble! Ultra-high efficiency MOSFET field-effect transistors, high current terminals & wiring, and innovative cooling techniques are just some of the technologies Roboteq utilizes to make our controllers among the coolest running for their size.
Field & Battle Proven Quality
Roboteq controllers have demonstrated durability through rigorous factory life tests and years of operation inside thousands of user applications. However, nothing illustrates our product's toughness quite like this badly bruised unit. It was subjected to absolute brutality while surviving 200+ battlebot fights, during which the robot was regularly hammered, rammed into, and thrown up to 3m in the air!
Guaranteed Success and Satisfaction
Our controllers are among the most sophisticated around, but also the easiest to use thanks to detailed documentation, software tools and application examples. But should you run into difficulties, you can rest assured that you will get timely and accurate answers from out highly skilled Support team. After all, we can only succeed if you succeed!
BEST Product
I've worked with a lot of motor controllers and I have to say that so far these are the BEST I've worked with. Great job on the design and the software.
