Abstract
A control system for reversing the rotation of a field wound motor is used in electric power steering systems. The system responds to control signals from a control means 25 to energize opposite legs of a bridge circuit 14 to direct current through the field winding 10 in the correct direction. At the same time the armature winding is energized. The control system provides a failure detection means 18 for the checking of the various control signals and the operation of the system to determine if there is any system failure to provide for a failsafe operation.
