<P>PROBLEM TO BE SOLVED: To provide a motor which can achieve the control of noise radiation from a power cable for supplying power and an AC output cable and the control of torque ripple of a motor. <P>SOLUTION: A power driver 105, which outputs three-phase AC for driving a stator coil 103, is arranged within the stator 109 of the motor, and the stator coil 103 and the power driver 105 are brought close to each other. Consequently, the wiring from the power driver 105 for outputting three-phase AC to the stator coil 103 becomes short, and the noise radiation from the three-phase AC output cable becomes small. Moreover, the cable wire for supplying the power driver 105 with power is constituted of a circular bus bar 106, a hollow part is made inside the stator 109, and the circular bus bar 106 is arranged in the hollow part. As a result, the wiring for power supply from the power cable to the power driver 105 becomes short, so this motor can suppress the noise radiation, too. <P>COPYRIGHT: (C)2004,JPO |
