<P>PROBLEM TO BE SOLVED: To provide a unit for switching wire connection patterns suitable for the versatility of a motor by making its characteristics changeable. <P>SOLUTION: The unit is provided with a switch 30 is provided. The switch 30 makes wire connection patterns of coils L<SB>A1</SB>to L<SB>A6</SB>in six inter-electrodes A<SB>1</SB>to A<SB>6</SB>switchable so as to make the reactance of an armature winding 12a variable, makes wire connection patterns of coils L<SB>B1</SB>to L<SB>B6</SB>in six inter-electrodes B<SB>1</SB>to B<SB>6</SB>switchable so as to make the reactance of an armature wining 12b variable, and makes wire connection patterns of coils L<SB>C1</SB>to L<SB>C6</SB>in six inter-electrodes C<SB>1</SB>to C<SB>6</SB>switchable so as to make the reactance of an armature winding 12c variable. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
