<P>PROBLEM TO BE SOLVED: To provide an energization controller which can control currents in all N phases of motor-side armature coils, and which does not pose problems of destabilized operation or oscillation or incur an increase in cost, weight, or dimensions, even if a load current is increased. <P>SOLUTION: A motor is driven as follows: power is supplied from a power supplying means 2 to the armature coils of N phases, in a star connection; the currents in the individual phases are detected, and the power supplying means 2 is controlled by a current feedback circuit 3 to adjust the currents in the individual phases to proper values; a supply voltage is divided by a voltage dividing circuit 4 connected in parallel with a power supply and is outputted to its output end; the voltage dividing circuit 4 is controlled by a midpoint correcting circuit 5 with the voltage at its output end variable; the midpoint of the armature coils of N phases, the output end of the voltage dividing circuit 4 and the midpoint correcting circuit 5 are connected to each other. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
