HPEVS

Rejoice! Curtis's NEW 144 Volt Controller is NOW AVAILABLE!

Affordable, air-cooled AC induction drive systems that are available in six different motor sizes and horse power ratings from 18 to 89 HP peak. The ultimate in power and efficiency, AC drives offer the best regeneration, highest RPM, excellent torque, and are very reliable. Systems start at 36 volts and 75 ft-lbs of torque and go up to 177 volts and 185 ft-lbs of torque. At only a fraction of the cost of the earlier, water-cooled AC drives, these systems are capable of powering a variety of vehicles, including: go-karts, golf carts, motorcycles, cars, trucks, boats, specialty/industrial vehicles, and even some aircraft.

Our electric drive systems are sold as a complete kit that includes an HPEVS motor, Curtis controller, contactor, Spyglass display and your choice of throttle. When we say complete, we mean it! The Spyglass (model 840) displays rpm, controller/motor temperature, volts, and amps. Each Curtis controller is pre-programmed for your unique application. These systems do not require an additional inverter and use a DC battery voltage input. 

If you have any questions regarding your application of an AC motor kit, don't hesitate to call (707) 578-7973 between 9AM-5PM PST to speak with a specialist.
