AC Induction Motor Controllers
AC Induction motors are industry workhorses thanks to their simple and inexpensive construction. They are commonly used in traction for electric vehicles. AC Induction motors are being used increasingly in robotics and automation applications thanks to advanced electronic controls. Roboteq offers a growing line of single and dual channel Variable Frequency Drives for AC Induction motors, ranging from 60A to 500A per channel. Just match the voltage and current rating using our Product Tables below, or the Product Finder.
Ideal for Small EV's and Heavy Robots
AC Induction motors are among the simplest to interface. This is due to their only requiring a 3-wire connection to operate in their most basic mode. More efficient control can be achieved using advanced algorithems, such as Field Oritented Control (FOC).
Roboteq controllers can be used with practically any AC Induction motor within the specified Power and Voltage range.
Guaranteed to Work with Your AC Motor
Scalar / VpH
Simple, open-loop mode where Voltage and
Frequency change together at a fixed ratio
Pro: Simplest, always works with any motor
Con: Inefficient with variable load
Closed loop mode that adjusts Voltage vs
Frequency to keep slip within optimal range
Pro: Simple. Efficient, Easy to tune
Con: Not optimal. Speed control only
FOC - Torque Control
Efficient Closed Loop Torque mode that uses
Field Oriented Control
Pro: Most efficient
Con: Complex tuning
FOC - Speed Control
Efficient Closed Loop Speed mode that uses
Field Oriented Control
Pro: Most efficient
Con: Complex tuning
Four drive modes are available, ranging from the simplest Scalar to the most complex Field Oriented Control modes. Operating your motor will be a plug and play experience. Expert tools and support will allow you to fine tune and get the most of your motor.

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!
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.

Always Ready for the Unexpected
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.
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.
Guaranteed Success and Satisfaction
Our controllers are among the most sophisticated on the market, but also the easiest to use thanks to detailed documentation, software tools and application examples. However, should you run into difficulties you can rest assured that you will get prompt and accurate answers from our superb Support team. After all, we can only succeed if you succeed!
