PROBLEM TO BE SOLVED: To program an induction armature field corresponding to the speed of an automobile and reduce power consumption of a motor by providing a motor controller to control an induction armature field for the motor as the function of the running speed of the automobile in response to a typical speed signal from the automobile. ;SOLUTION: A speed sensor 118 jointed to the wheel of an automobile provided with a power steering device 1 generates speed information signals fed to an electric controller 120 for the automobile and address signals fed to a magnetic field mapping table to operate a motor 102 in accordance with the speed. The controller 120 operates a relay 124 and generates power steering instruction signals to connect or disconnect power from a power invertor or an induction armature controller 126 for activating or stopping the power steering device 100. An induction field around the armature or rotator of the motor 102 is controlled by a speed following field program contained in the magnetic field mapping table 122.;COPYRIGHT: (C)1997,JPO
