1222-5101 AC STEERING CONTROL

Description

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.
