The Curtis AC F2-T and AC F2-D motor controllers simplify vehicle design by integrating dual AC traction motor control into a single compact, rugged controller. The AC F2-T adds integrated DC hydraulic pump control, enabling OEMs to manage traction and hydraulic functions from one device while reducing wiring, components, and overall system complexity. Designed for dual-drive electric vehicles, these controllers deliver efficient performance, responsive vehicle control, and advanced system management capabilities.

Built on Curtis' proven field-oriented control technology, the AC F2-T/D provides independent, precise control of two AC induction or PMAC traction motors, enabling smooth steering, traction, and maneuverability. The AC F2-T additionally delivers accurate control of DC hydraulic pump motors and proportional hydraulic valves, making it well suited for electric aerial work platforms and other machines requiring coordinated traction and hydraulic operation.

Dual ARM Cortex microprocessors provide high-performance motor control and category 2 functional safety while supporting advanced vehicle management functions. Flexible I/O, CANopen and J1939 communication support, and Curtis Vehicle Control Language (VCL) allow the controller to operate as a vehicle system controller, eliminating the need for additional hardware and simplifying machine integration.

High-efficiency power conversion helps maximize battery runtime, while configurable CAN communication and VCL enable seamless integration with battery management systems and other vehicle subsystems. Advanced diagnostics, fault logging, and CAN-based programming simplify development, commissioning, troubleshooting, and service.

Designed for demanding mobile equipment environments, the AC F2-T/D features a compact IP67-rated housing resistant to oils, solvents, degreasers, and other industrial chemicals. The result is a durable, reliable motor control solution that helps OEMs accelerate development while delivering the performance and functionality operators expect.
