The Curtis Model 1220 is a brushed DC permanent magnet motor controller for electric power steering, steer-by-wire systems and only works with Curtis VCL enabled AC traction controllers. The steering motor functions as an actuator to change the angle of the wheel(s) thereby changing travel direction. Model 1220 interprets the steering command input and wheel position feedback, driving the steering motor to move the wheel to the desired position. Intended applications are Class 3 material handling vehicles such as pallet trucks, stackers and other similar industrial vehicles.
