<P>PROBLEM TO BE SOLVED: To provide a DC motor control device, which supplies a DC voltage to a DC motor with an AC-DC converter and supplies a DC voltage to a microcomputer with a DC-DC converter operating on an output voltage of the AC-DC converter, the DC motor control device capable of generating a stable DC voltage while suppressing power consumption. <P>SOLUTION: The DC motor control device includes voltage regulators 3, 4, 8 for lowering a first DC voltage Vdc2 supplied from an AC-DC converter 1 to a DC-DC converter 15 on the basis of a voltage switching signal X output from a microcomputer 9 in a standby mode, and a switch 12 for shutting down supply to a motor drive circuit 7 of the first DC voltage Vdc2 on the basis of a control signal DV1 output from the microcomputer 9 in a standby mode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
