1222

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 Model 1222 performs as the steering system controller, interpreting the steering command input and wheel position feedback, then driving the steering motor to move the steered wheel to the desired position.

Designed for 300–1500W AC induction gearmotors. Intended applications are materials handling vehicles such as reach trucks, order pickers, stackers, ‘man up’ warehouse trucks and other similar industrial vehicles.
