<P>PROBLEM TO BE SOLVED: To provide a motor driving system for reducing private wiring for supplying power to a peripheral device except for an electric motor. <P>SOLUTION: The motor driving system 100 is provided with the electric motor 6, a driver circuit 4 which is connected to the electric motor 6 through a transmission path 5 and generates a plurality of drive voltages for driving the electric motor 6, and a power supply circuit 8 generating power from the plurality of drive voltages flowing in the transmission path 5 and supplying power to a position detector 7. When the electric motor stops, a phase difference occurs at least in one group of drive voltages. <P>COPYRIGHT: (C)2008,JPO&INPIT |
