Quality, Power and Performance
for Optimum System Response

Climbing a hill in a golf car or moving thousands of pounds on a forklift truck, you can depend on Curtis controllers mile after mile, load after load. For decades Curtis motor controllers have set the industry standard for consistently high performance, safety and reliability. That’s why Curtis controllers are on millions of electric vehicles all over the world.

Smooth, precise control sets Curtis apart from other controllers. Accelerating or decelerating, downhill or uphill, half-throttle or full-throttle, Curtis controllers enhance vehicle response with a difference you can feel. Our controllers reflect years of experience working with design engineers of major OEMs worldwide. We listened to the rigorous requirements of your customers, and tailored our controller technology for their special applications. That’s why our motor control software ensures the best throttle response and efficient motor drive. Our hardware designs provide environmental ruggedness and cool, reliable operation.... And our patented power electronic circuits are recognized as the industry’s best.

Curtis set the pace for CAN technology, advanced system integration and created best-in-class SepEx® Separately Excited controllers. We pioneered the use of High Speed MOSFETS in low voltage, high power control. Now we’ve done it again with the new Curtis Vehicle Control Language – VCL. VCL combines the power of an AC motor controller with the flexibility of a Programmable Logic Controller to give you the most adaptable motor speed drive available.

When it comes to motor controllers, we’re perfectionists. You see it in the aesthetic, robust design. You feel it in the solid heft of the cooling plate. You experience it during the simple installation and programming. You enjoy it in the smooth, controlled drive. Exceptional performance tells you it’s a Curtis controller, built to surpass your most exacting requirements.
