<P>PROBLEM TO BE SOLVED: To provide a motor controller having high reliability by certainly preventing the generation of a 200V short circuit line and to provide a garbage disposer using the same. <P>SOLUTION: The motor controller includes one or more sets of forward direction power supply lines 13 wired so that the phase sequence of a three-phase AC power source 2 and a phase sequence of a three-phase AC motor 9 become the same, one or more sets of backward power supply lines 14 wired so that the phase sequence of the three-phase AC power source 2 and the phase sequence of the three-phase AC motor 9 become different, and drive means 16 for respectively separately controlling the power supplies of the three phases of the lines. The motor controller further includes switching means 15 for switching the rotating direction of the three-phase AC motor 9 by switching the forward direction power supply lines 13 and the backward direction power supply lines 14. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
