AC Motor Controllers

This new AC induction motor controller (inverter) uses dual high performance ARM Cortex microprocessors in an compact, package to deliver unmatched performance and a very flexible feature set. Model AC F2-A is fully optimized for use as a traction controller on 1.0 ton-2.0 ton class III pedestrian-operated powered pallet trucks. It provides vehicle designers with the ability to fully define and control the detailed dynamic performance of their vehicle's drivetrain, and also provides comprehensive vehicle management and CAN master capabilities. Model AC F2-A is also suitable for traction or hydraulic pump control on other types of battery powered vehicles.

The Curtis Model 1222 is an AC induction motor controller for 'steer by wire' electric power steering systems. In these systems, the steering motor functions as an actuator to change the angle of the vehicle's steered wheel(s) and so change the direction of travel.

The Curtis model 1232E provides advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties and offers the highest levels of functional safety.

The Curtis 'SE' AC controllers utilize the latest technology to increase the peak current ratings for each size of controller. For a given rating, the SE models are smaller and lower cost than previous Curtis AC controllers, benefits that are highly advantageous for all types of applications.
