<P>PROBLEM TO BE SOLVED: To provide a motor control system for power assist capable of responding to sensor output at a high speed. <P>SOLUTION: This system consists of a plurality phases of stators 10, 12, a moving element 14, exciting means 16, 18 which alternately excite the stators into different poles, a control circuit for outputting a load connected with the moving element and an excitement signal to the exciting means, a polarizing means for alternately polarizing the moving element into different poles, and a means for controlling the control circuit so as to output the excitement signal to one phase of the stator of the control circuit when stress is applied to the load and then output the excitement signal to the other phase of the stator to operate the load in the direction of the stress. When an outside stress is applied to the motor, a driving signal is supplied to the motor, thus realizing a required power assist mechanism. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
