<P>PROBLEM TO BE SOLVED: To provide a motor control device that avoids the influence of switching noise. <P>SOLUTION: The motor control device comprises microcomputers 3-1, 3-2 to 3-M that take in currents outputted to a motor to be controlled, output switching signals SW obtained by comparing a voltage command signal that is a modulated signal and a carrier signal, and control the motor to be controlled; and a clock generation IC 5 that generates clock signals. The microcomputers 3-1, 3-2 to 3-M output the switching signals SW in synchronization with the clock signals, and take in the currents at such timing as to except outputs of the switching signals SW of the other microcomputers 3-1, 3-2 to 3-M including one itself. <P>COPYRIGHT: (C)2004,JPO |
