<P>PROBLEM TO BE SOLVED: To provide a motor control device that allows a single drive circuit to drive a three-phase motor and two DC motors. <P>SOLUTION: A telescopic motor 8 is connected between a U-phase wiring 15 and a V-phase wiring 16 through a second feeder circuit 21, 22 and a telescopic relay R1. A tilt motor 9 is connected between the V-phase wiring 16 and a W-phase wiring 17 through a third feeder circuit 22, 23 and a tilt relay R2. In a sixth mode, a first FET 1 and a sixth FET 6 are turned on, a fourth FET 4 and a third FET 3 are alternately turned on and off, and, in synchronization, the telescopic relay R1 and the tilt relay R2 are alternately turned on and off. <P>COPYRIGHT: (C)2012,JPO&INPIT |
