<P>PROBLEM TO BE SOLVED: To provide a motor driving system and a motor driving method for surely detecting a position even when switching noise occurs. <P>SOLUTION: The motor driving system 100 has an electric motor 9, a motor driver circuit 2 for driving the electric motor 9 by switching-operation, a position detector 10 for detecting a position of the electric motor 9, and a control part 1 for controlling the motor driver circuit 2 on the basis of the detection result of the position detector 10. The control part 1 has a PWM generation circuit 11, which is connected with the electric motor 9 via a transmission path 6 so as to generate a plurality of drive voltages for driving the electric motor 9, a feedback circuit 12 for feedback-controlling the PWM generation circuit 11 on the basis of a position detection signal from the position detector 10, and a switching stop circuit 13 for temporarily stopping switching of the drive voltages in the PWM generation circuit 11. <P>COPYRIGHT: (C)2009,JPO&INPIT |
