<P>PROBLEM TO BE SOLVED: To provide a configuration of a brushless motor system capable of improving an adverse effect of electromotive noise without need for enlarging a filter or high performance. <P>SOLUTION: In this brushless motor system equipped with a brushless motor, an inverter device and a DC power supply, a noise circulation line for circulating noise current is connected to between the brushless motor and the inverter device. The noise current occurs in the inverter device and reaches the brishless motor. Attachment of the noise circulation line can reduce a common mode current leaking from the brushless motor to the ground. <P>COPYRIGHT: (C)2007,JPO&INPIT |
