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

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.

Mode Feedback Description Advantages/Disadvantages
Scalar / VpH None 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

Controlled Slip Encoder 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 Encoder  Efficient Closed Loop Torque mode that uses Field Oriented Control

 Pro: Most efficient

Con: Complex tuning

FOC - Speed Control Encoder  Efficient Closed Loop Speed mode that uses Field Oriented Control

Pro: Most efficient

Con: Complex tuning

Interface with Anything

connect all tr

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 Output are provided for brakes, 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


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 AC Induction Motor Controllers!

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.
